Alien hovercraft or possibly an Altocumulus lenticular cloud excites Catalina residents

I first noticed the craft as I was driving up Golder Ranch Drive. At first I thought it was just an Altocumulus lenticularis…  Really didn’t think that much about it.  We seem them over there all the time.

But it was unusually smooth, I thought, and had a slightly humped up portion on the top I could see after I zoomed in on it.   Could it be a cloaked alien space vehicle? Time would tell.

A lenticular expands and contracts while hovering over the same spot. This can go on for hours!  But, as you will see, over the next 20 minutes, this cloud, or “craft” did not change in any way, clearly evidence of a cloaked space vehicle!  Way too smooth to be a real cloud!

Since it didn’t seem to be doing anything, maybe just spying on me and us as do virtually all institutional entities these days,  I lost interest in it and continued doing yard work….

12:47 PM.
12:48 PM. Zoomed in….
1:00 PM. Seems to be taking an interest in Charlotte’s house next door, kind of floating over it. Hmmmm.
1:01 PM. After I looked away, it seemed to have leapt back over Charouleau Gap!
1:01 PM. As I zoomed out my camera, the object seemed to be getting smaller, perhaps moving away finally! I felt relieved and went back to raking the fall  leaves.  But, we don’t have leaves here, so what was that about?  Had I been infected?  Taken over?

Later, completely different looking clouds came over, Altocumulus tending toward castellanus variety…making the early afternoon smooth-looking cloud more anomalous.

2:42 PM. Bands of Altocumulus clouds worked their way over Catalina and environs, the craft or lenticular cloud long gone.  Or, wait a minute!  Is that it there on the horizon???
2:42 PM, looking farther to the SW. You can see how different these clouds look compared to the “lenticular.”

PS:  It been said that the UFO craze began with an Altocumulus lenticular cloud in the lee of Mt Rainier in the late 1940s.  Why not see if we can start a new craze right here in Catalina?  Been abducted lately?

 

The End, for now

Cirrus uncinus scenes for a lifetime, well, mine, anyway

I hope you had a chance to venture out late yesterday morning and see some of the most spectacular Cirrus (uncinus) displays with HUGE streamers that you will ever see.

The early Cirrus cloud were nothing very special, not showing clues about what was to happen a few hours later:

7:46 AM. A complex sky with Altocumulus on the right and various species of Cirrus such as Cirrus spissatus, center.

But by mid-morning, racing in from the west, these:

10:58 AM. From the Rillito Bridge at Swan, this amazing scene with Cirrus uncinus and those gigantically long tails of ice!
11:08 AM
11:08 AM. Mimics trees in a way, both reaching upward.
11:14 AM.
11:12 AM. From the Rillito Bridge at Swan again.  Kind of running around like a chicken with its hat off!  The heads of the Ci unc are overhead.
11:11 AM.
11:14 AM. One final shot.

—————

There was an interesting  contrail distraction later that day.  Are these “castellanus” crenelations, or is it perspective?  Those knobs are usually pointed downward due to the action of the wingtip vortices that take them downward behind the plane.  Maybe they’re just sloped down at us, not puffed up.

1:10 PM.

—————-

Late in the day some Altocumulus advanced from the west, providing a nice sunset, but a layer once again impacted by aircraft holes.   Can you find them (with their trails of ice slanting downward?)

5:38 PM.

The End

Well, there is still a chance of some rain late in the month, late or after the TG holiday weekend…..  FIngers crossed.   Poor wildflower seeds.

A day dominated by cold Altocumulus punctuated by aircraft-produced hole punches and ice canals

Hope you saw them and recorded them in your cloud and weather diary.  I’m thinking that at the next Cloud Maven Junior meeting we should devote a lot of time to this issue.  It was a rare day yesterday that the WHOLE day had that phenomenon occurring as aircraft penetrated those clouds, usually on ascent or descent.  Sharp descents/ascents produce holes.  See the sequence below if you don’t believe me (ppt from a recent talk):

Aircraft inadvertent cloud seeding for Julie Mc.

Yesterday’s clouds:  lots and lots of  aircraft-produced ice

(btw, see note below about pop-up ads in this blog, ones that started to appear after downloading latest WP software)

6:44 AM. Altocumulus at sunrise. As we say so many times here in old AZzy, “So pretty.”
Also at 6:44 AM. From a smartphone, color not so great, though not bad either.
U of AZ Wildcats balloon sounding, launched at about 3:30 AM yesterday. Those Altcumulus clouds were way up there for Altocu, 22,000 feet above Catalina, 25,000 feet above sea level.because they were so high, were so cold, AND were composed of supercooled liquid water, they ripe for aircraft to create ice going through them, likely on climb out and descent from TUS and perhaps PHX as well, Davis-Monthan.  What was unusual, was that it was happening most all day as the clouds filled in some.  They remained liquid, high, and cold.

7:23 AM. Wasn’t long before aircraft made their presence known in this cold, cold layer.
6:54 AM. I should point out that a colder topped Altostratus layer was present to the N. Its not represented well in the TUS sounding. That layer was all or mostly all ice (the rosy colored segment of this photo).
7:37 AM. An unperturbed view of Altocumulus perlucidus (“Mackerel sky”). Are there any mackerel left?    Also, from a cloud viewing standpoint, these are much higher than one would guess. The fact that aircraft were making ice in them is a clue that they were higher than we would normally think of a “middle-level” cloud.   I like patterns like this.  I thought you would like to know that about me.
9:03 AM. Slicing and dicing. An aircraft has left a contrail through a Altocumulus line . What’s really unusual here is the ice contrail so far outside the liquid water cloud. It is thought that hole-punch and ice canals are limited to regions where there are liquid droplets, and so this is quite an anomaly, one that suggests the humidity was almost 100% with respect to water outside the cloud boundaries. Also, can you just make out the partial 22° halo, indicating very simple ice crystals like columns and plates?  Streamers of tiny ice crystals are also evident, trailing to the right, below the contrail?  This shows that the wind decreased rapidly with height just below the flight level, but was still from the southwest to west.
9:24 AM. Coming at you, another ice-canal has formed SW-W of Catalina, a favored locale for the formation of these canals on days like this.
9:40 AM. What’s left of it is almost to Catalina.  Note streamers of ice.  Below, a close up of a couple.
9:40 AM. The intensity and narrowness of these streamers point to an artificial origin. So, even if you didn’t see the canal, and here, some of the clouds are reforming at the top of the streamer, you would make a good guess that this was not natural ice.  Sometimes the canals can fill back in if the air is in overall ascent at cloud level.
9:57 AM. Here’s what those contrails in Altocumulus look like as they first appear. Can you spot’em? There are two.
1:45 PM. Another aircraft-produced ice event as the Altocumulus increased and became thicker, making detection of these events less obvious. Sometimes a canal clearing is very muted.
4:12 PM. Aircraft-induced hole punch cloud with ice below the hole. Can you spot it? See close up below.
4:12 PM. Close-up of that hole punch, ice mostly below the Altocumulus layer.
4:35 PM. That hole punch cloud 35 min later. The long trail indicates high humidity well below the Altocumulus layer in which it appeared.
The 3:30 PM balloon sounding from the U of AZ. A study in ambiguity.
The day ended with an unusually bright sun dawg, mock sun, or parhelia. So bright it did, again, suggest a plume of ice from a prior aircraft passage through extra cold Altocu or Cirrocu clouds. But, just wild speculation here.  Hope you don’t mind.
5:41 PM. Nice sunset, but one strongly impacted by clearing from aircraft-produced holes and lines of ice, the ice now mostly gone.

The End

 

——————About those nuisance ads—————

Note to me and the two other people that drop by my cloud or “clod” blogulations:  The embedded pop-up ads are due to a WP third party plug-in that needs to be repaired.  It will likely happen today.

 

After consultations about ads…

Oddly,  those pop-ups and blue highlighting and double underlining do not seem to be present outside of my personal view of my own blog, this according to hoster, “godaddy.”  Even using a different browser other than FIrefox does not show them as I have just verified.

 

Less data; but more filling

A “storm”, one with “rain,” has at last shown up in the numerical prognostics for late on Thanksgiving Weekend.  It appears for the first time on last night’s 11 PM AST model run.  At that time (11 PM AST) we have less global data to work with when the model crunches out its forecast, and so it is generally thought to be less reliable.  But, it has a storm for us….

But, a storm here helps fill dreams of a green desert washed of dust, and stimulates the thought of wildflower seeds springing to life for the spring to come.  So, to HECK with opinions on a 11 PM run having less skill!  Let us dream of rain and poppies!  Here it is below, from IPS Meteostar:

Valid on Saturday, November 25th, at 11 PM AST. As shown, rain would be imminent or underway with this upper level configuration. If it verified, might produce half an inch or so in Catalinaland.  That next trough would tend to follow in its path for a second rain a few days later.  This is so far out from now, we often call these kinds of depictions, “mythical.”  Take under advisement.  Also, this kind of depiction of a deep trough marching across old AZy wasn’t there on the prior run at 5 PM AST.  Going on a  hunch is all , that something will come through then.
From the NOAA spaghetti factory: Not a lot of support, either. Those blue lines (contours of the flow) should be bunched down in the SW if the forecast above, so far out in time, is going to have any reliability at all. It really doesn’t. Going on a hunch based on wishful thinking, like thinking Washington (former company team) was going to defeat Stanford last night….   🙁

 

Pretty Cirrus lately, often at multiple levels, as here:

12:13 PM yesterday. What’s a cloud-maven site without a cloud, at least one shot?  Can you tell that there are Cirrus clouds at different levels?  Notice crossing patterns, one clue.

The End

Some recent pretty clods

Been busy as a briefly unretired science worker (gave a stressful talk at a university last week) and thought maybe a lot of usual drop ins to this site might not anymore.   So, in the title for today,  am reaching out to a new demographic: persons interested in congealed soil matter.  They might later, after stopping by, discover a new interest; that in clouds, pretty ones.  Most of the cheap tricks I try like this don’t have any effect, though.  Oh, well.

Let us go forward after backing up:

November 3rd

8:01 November 3rd. OK, I’m way behind! Flock of Cirrus uncinus overruns Catalina and environs.
8:02 AM. Looking SW from Catalina. So pretty with the deep blue skies we have at this time of year due to sun’s lower angle in the sky.
9:16 AM. Look how different, even unreal, that flock of Cirrus looked when leaving us. Looking NE toward the Charouleau Gap.

But the Cirrus kept coming and more odd sights were seen:

10:06 AM. Two levels of Cirrus can be seen. This vertical white patch is likely a few thousand feet lower than the crossing faint strands center and right side,  which are likely above 30,000 feet above the ground.  The heavier Cirrus (spissatus) in the distance is also lower than the strands.

Heavier Cirrus, increasing and lowering to Altostratus finished off the day as a heavy shield of middle and upper clouds raced toward southern Arizona from the Pacific:

3:08 PM. Cirrus spissatus here, too splotchy in coverage to be Altostratus. Nice subtle lighting effect on the Catalinas…

 

“Due to time constraints, we move ahead in the action…”

November 4th

7:27 AM. Classic A row of Altocumulus floccus and castellanus underlie an Altostratus layer.  Where the bases have disappeared, at right, are termed “floccus”, if you care.
8:00 AM. Altostratus, some lower Altocumulus  castellanus with graniteen boulders and a coupla saguaros.
8:59 AM. Bird collective watches in hopes that the darkening, lowering Altostratus layer  (with some Altocumulus) will bring rain. It didn’t. “Dang”, we say here.
4:51 PM. All of the higher layers were gone, leaving only a lowest, but thin scattered to broken Stratocumulus clouds. 🙁  All in all, it was a good day for hiking and other outdoor activities.

Sunday, November 5th:

6:01 AM. Flock of CIrrus uncinus and spissatus again advances on Catalina.
6:21 AM. a closer view. Here they seem to be uncinus with fibratus. Stratocumulus clouds were topping the Catalinas, too, indicating more humidity than we have been seeing most of the past few weeks.
8:38 AM. I thought this was an especially spectacular scene, this lattice of Cirrus racing toward us.  Hope you did, too.

4:26 PM. Perhaps the brightest example of iridescence I have ever seen! Just spectacular for a few seconds in this patch of Cirrocumulus. Iridescence is caused by diffraction around the tiny of droplets, less than 10 microns in diameter, as are present when a cloud just forms.

5:09 PM. Seeing this scene of Altocumulus, you KNEW you were in for a superb sunset.  It didn’t disappoint.
5:39 PM.
5:40 PM. There is no virga here.
5:44 PM. Super!

The weather just ahead

The Wildcat Weather Department model is foretelling perhaps a measurable rain event between this afternoon and tomorrow morning at 7 AM!  Heavier rain is foretold to be south of us, but just a slight error would mean something more substantial.  Hoping for error!  A sky covering Altostratus layer is just about assured with a lowering tendency as the day goes on.  Should see some Altocu , too, a day a lot like last Saturday.

The End

Raindrops fall on Catalina ending rainless October

A trace of rain was officially recorded in Catalina at this site ending prospects of a rainless October.  It fell from high-based Cumulonimbus clouds in a band, partially lining the NW horizon that could be seen as the sun rose yesterday.  Some ants were injured by the falling drops, ones that reached millimeter sizes and fell at 5-8 mph, though in some areas, winds of 10-15 mph added to drop impacts.  Flying insects, while  obliged to avoid the watery missiles, were able to do so with ease due to the appreciable spacing between the drops of several feet.

Due to the short-lived hydrometeor events, many humans were unaware that rain had fallen in Catalina on more than one occasion yesterday.  That’s why we blog here.  Weather and cloud news you can rely on.

How high were the bases of those precipitating clouds spewing snow virga that melted to rain?  Higher than the freezing level! Haha..  The balloon sounding profile started with the Altocumulus perlucidus layer at 18,000 feet above sea level, 15,000 feet above Catalina, bases at -11°C.  By evening the lowest moist level had lowered to 14,000 feet ASL (11,000 feet AGL) and -3°C.  However, that last moist level had to be a bit lower than those snowy cloud bases IMO–we know that the moist level almost always lowers.

So cloud maven person will make the definitive call that the rainy (well, sprinkly) cloud bases were at 16,000 ASL (13,000 feet AGL) when they passed over, if that makes any sense or is anything you really care about.

Yesterday’s clouds

6:42 AM. Altocumulus perlucidus at -11°C (12°F). No ice evident.
6:43 AM. High-based Cumulonimbus erupts to the distant NW. Altocumulus castellanus layer from which it erupted can also be seen. The snow falling from cloud base is also evident, melting to rain just above the horizon.
6:54 AM. By this time the full band to the NW whose tail was to pass over us about mid-day is evident. Plenty of snow can be seen falling from these modest, high-based Cumulonimbus clouds.

 

As rain fell……this sky, 12:30 to 1 PM:

Kind of pathetic really; no shafting whatsoever, much less virga than on the horizon yesterday morning.  So our end of that band was so weak it was just barely able to get some drops to the ground.

Looks like this is it for rain in October 2017.  However, November 2017 appears to look much brighter for substantial, dust-removing rains in Catalina beginning in the first 10 days!

The End (I missed the sunset due to a social engagement–hope you saw it wherever you were).  Probably was pretty nice.

A study in cold Altocumulus and about a balloon mistaken for a space object

Balloon sounding released from the U of AZ about 3:30 PM AST. Altocumulus clouds were no less than 21,000 feet above Catalina at -20°C (4°F).  Sounding courtesy of IPS Meteostar.  BTW, it wasn’t this balloon–see below.
11:15 AM. A stationary balloon that hovers SE of Tucson.  Can you find it?  I had never noticed it before and at first thought it was in space, above the Cirrus!  How crazy was that?  Likely to be a device up there  to monitor the US Border.
2:55 PM. Cirrocumulus with an aircraft produced ice canal in it , tight half of photo (that ice cloud now termed, “Cirrus anthropogenitus”).
4:02 PM. A complex sky for sure. Little tufts of Altocumulus way up at 21,000 feet above ground level, with Ac castellanus turrets (e.g., left above horizon).  SInce those turrets are reaching up to temperatures well below -30°C (-22°F)  they’re converting to all ice (such as center right).   Those icy ones would be called, “Cirrus spissatus.”  It would also not be untoward, and I know you don’t want that, to just call those deeper clouds with turrets on the left, “Cirrus castellanus.”

5:56 PM. Lines of Altocumulus make for an OK sunset.

Another pretty cloud day ahead.  Though most of the Altocumulus clouds are flat, there are some whoppers off to the north now, Ac cas so large they might have to be called Cumulonimbus, certainly large enough to produce radar echoes, maybe a sprinkle at the ground.

Lots of wind tomorrow, as you likely know,  but no rain in sight still.  So, October almost surely will end as a rainless month.  Our average for October is just over an inch of rain!

The End

Pretty sunrises/sunsets ahead and that’s about it for October

Footnote


A warm, rainless October appears to be our fate, much like last year when only 0.01 inches fell.  Oh, me.  Our dryness since the end of July,  with so many cloudless skies, continues on and on.  Tough to take  if you’re cloud-centric.

However, this month, though likely rainless, promises to deliver some great sunrises and sunsets as weak regions of rising air  pass above  us in the days ahead, that rising air showing up as lots of middle and upper level clouds like Altocumulus,  Altostratus with virga, and CIrrus over many of the remaining days.  Those kinds of clouds can be associated with the most spectacular ones sunrises and sunsets.

I guess that’s something.

Below, a sample pretty scene for cloud-starved readers.

Taken by the Arthur on a University of Washington research flight in the early 1990s. The scene is the Willapa Bay Wildlife Refuge, Washington. We were studying the lifecycle of Cumulus clouds and the aerosol environments affecting them. On this calm day, Cumulus could form over the tiniest strips of warmer land. You would not see this scene on a windy day. So, the shot is not only “pretty”, but an unusual one.  I was so lucky to have seen so many pretty scenes in research!

Clouds continue to beguile, even when they’re tiny

As here,  just to reinforce that assertion a bit.  Its a link to a recent blog by my cloud-obsessed friend and author, Maria Mudd Ruth.  I strongly recommend buying a few of her books.  Really,  I do!

But in viewing our deep blue skies, pocked with little fluffy Cumulus clouds over the past two or three days, you would not need convincing that even tiny clouds are beguiling, a wonderful attribute for a planet to have.  Having mountains on a planet is great, too, and watching the interplay of clouds and their shadows on them is a never ending pleasure.  We’re pretty lucky when you think about it to be on a planet like this one.  Hope you think so, too.

No rain ahead, glumly, though some sprinkles are out there this morning as frontal cloud band passes over.  Just a little too high off the ground for real rain.  And the cloud tops aren’t quite cold enough to form much ice, too.  Those cloud tops get colder going to the NE, and so higher terrain up thataway (e.g., Show Low) are getting some light rain this morning.  Right now, there’s a little sprinkle just beyond Romero Canyon, so we got a little ice this morning in them clouds.

What was interesting is that I never saw no ice yesterday, to continue the slang of rock and roll, in another cheap attempt to reach out to another demographic.   The clouds were just a bit too warm for ice-formation, tops running in the -4°C to -5°C range according to yesterday afternoon’s Banner University of Arizona’s balloon sounding.  Some may have bulged up to nearly -10°C, but still not quite there.  I looked constantly for signs of ice and never saw none, and neither did you, of course.

The U of AZ balloon sounding for yesterday afternoon, released about 3:30 PM AST.
The U of AZ balloon sounding for yesterday afternoon, released about 3:30 PM AST, courtesy of MeteoStar., I hope.

Bases were cool, at about 4°C, at 11, 000 feet above sea level, or 8,000 feet above Catalina.  Tops, about 15,000 feet above sea level.  So, they were running around 3,000-4,000 feet thick with no ice.   This was a situation where dropping dry ice  into those clouds would have created snowfall, then sprinkles, that would not have fallen naturally.  Doubtful anything would have reached the ground anywhere near our elevation, however, but up  at Ms. Mt. Lemmon, something would have likely even measured from doing that far enough upwind.

In summary, yes, there are some fairly rare times you can get some precip out of clouds by seeding them and yesterday was one of them1.

Today the clouds are thicker, drop sizes therefore larger in those tops of a cloud band similar to the one we had yesterday evening.  As drop sizes increase, the temperature at which they freeze also increases.  Well, at least that’s what we found over and over again at the U of Washington.

The balloon sounding launched about 3:30 AM this morning from the U of AZ. Our cloud band is almost twice as thick as it was yesterday afternoon as bases lowered and tops went up some.
The balloon sounding launched about 3:30 AM this morning from the U of AZ. Our cloud band is almost twice as thick as it was yesterday afternoon as bases lowered and tops went up some.  The sounding, too, went right up into the middle of that band, now exiting the area.

The result, some ice has formed even though they’re hardly colder than just -9°C or -10°C (14°F).  Check the radar:
