“Deception at its finest”….a study in cloud perspective

I am sure that many of you saw this last evening:

4:17 PM. Line of spreading out Altostratus translucidus.
4:17 PM. Line of spreading out Altostratus translucidus.  Many of you might have added, “radiatus” to that cloud name.  “Clearly” it is widening as it passes over.

While I hate to embarrass cloud acolytes, here’s the simultaneous satellite view, courtesy of our Banner University of Arizona Weather Department:

AZC
4:00 PM AST. That line of ice cloud looks pretty straight doesn’t it? Imagine how wide a cloud would have to spread, after seeing that Altostratus photo, to REALLY be radiating, spreading out!

As Einstein wrote, “Things are not always as they seem.”

Now, for the snow report

…from the Lake Tahoe area (after all, we made a BIG DEAL out of the incredible NWS, Reno, forecast in the prior blogulation):

0822 AM     HEAVY SNOW       NORTHSTAR               39.28N 120.12W
01/11/2017  M42.0 INCH       PLACER             CA   PUBLIC

NORTHSTAR AT TAHOE REPORTED 42 INCHES OF NEW SNOWFALL IN  THE LAST 24 HOURS. 48 HOUR TOTAL OF 78 INCHES AND A 7 DAY TOTAL OF 122 INCHES1.

Looks like a bite has been taken out of the Cal drought this water year, a drought it was said would take years to end!  Folsom Lake, near “Sacramenta”, Cal,  has risen 30 feet in the past 30 days! Oh, my.

Now for some more of them cloud pictures…

Been holding out as other chores fill up the day:

7:19 AM, Jan 10. Pretty Altocumulus, some Cirrus above.

7:19 AM, Jan 10th. Time seems to be standing still, as we look a a cloudlet spewing heavy virga.
Also 7:19 AM, Jan 10th. Time seems to be standing still, as we look a a cloudlet spewing heavy virga.
7:22 AM, Jan 10th, time moving ahead again. Close up of that Altocumulus with virga. Top must have been turreted, colder maybe a half hour or hour before this photo to have so much ice compared to its brethren.
7:22 AM, Jan 10th, time moving ahead again. Close up of that Altocumulus cloud with virga. Top must have been turreted, colder maybe a half hour or hour before this photo to have so much ice compared to its brethren.  That’s the learning part of this sequence.  Doesn’t look like an artifact from an aircraft because there is droplet cloud at the top, and not just a clear spot, which usually happens when an aircraft makes ice in a “supercooled” droplet cloud.
5:14 PM, Jan 10th. THought this was a neat scene, Cirrus uncinus, the long trail of ice crystals falling behind, the overhead view.

12:57 PM, Jan 8th. Makes you want to cry... This Cirrus spissatus is trying so HARD to be a precipitator to the ground, and doesn't know that those bottom ice crystals are evaporating 25,000 feet above it.

The weather just ahead

U of AZ latest mod output (from 11 PM AST last night) has a substantial rain on the doorstep.  Starts here in Catalina Saturday afternoon with projected totals over half an inch nu mid-day Sunday.  Check it out:

Totals valid at 11 AM AST, Sunday, Jan. 15th.
Totals valid at 11 AM AST, Sunday, Jan. 15th.

HECK, this storm wasn’t even predicted 10=12 days ago!  The major weather change was indicated about the 20th, plus or minus a day.  Those storms, indicated in the NOAA “spaghetti” plots more than 12 days ago, are still in the pipeline after we have a brief “recovery” from the “surprise” storm about to arrive on Saturday!  Yay.

This sequence of storms is so great for the AZ water situation, too, as well as giving it to Cal good again around the 20th as well.  No doubt, as the humans we are, the peoples of Cal  will be complaining about TOO MUCH WATER!

This will lead to apathy about water issues, you can bet on it!  See the well-known “cloud seeding cartoon” about drought and apathy posted so many decades ago in a journal article on cloud seeding by editorial nemesis1, Bernard A. Silverman, J. Appl. Meteor.,
termed the “Hydro-illogic Cycle”:

Published in 1978, but was around in the cloud seeding culture for many years before that. Used without permission. hahaha
Published in 1978, but was around in the cloud seeding culture for many years before that. Used without permission. hahaha  I believe it was drawn by the founder of Atmospherics, Inc., Tom Henderson’s daughter.  Atmospherics, Incorporated performed numerous cloud seeding operations in the US and around the world beginning in the early 1950s.  Yours truly worked for them on several occasions in the  early 1970s as a “radar meteorologist” directing seeding aircraft.  Later, I became a published critic, mostly with Prof. Peter V. Hobbs,  of a number of cloud seeding projects.

The End
——————————-
1Nothing yours truly submitted during the era of BAS as Editor of the J. Appl. Meteor. “got in”, including the benchmark paper reporting that our own aircraft was creating ice in clouds at temperatures as high as -8° C.   Three sole-authored papers critical of cloud seeding that I submitted were rejected in 1983 alone!  All or parts of them were published years later.

The paper on our aircraft, submitted originally in 1981, was rejected twice before being accepted and published in 1983. The effect was confirmed in experiments conducted in the Mono Lakes area in 1991, by the president of Atmospherics, Inc. mentioned above! Aircraft produced ice particles at unexpectedly high temperatures is a now well-known phenomenon that researchers have to be aware of when re-sampling the same cloud with an aircraft at below freezing temperatures.

Soap box:  It really is the editor of journals that determines whether you’re going to get in or not. They know, or should know, those who are going to keep you out or not, those with axes to grind, and those who are more objective.  However, let me say this, I like Bernie.  Has a great sense of humor. Below, Bernard A. Silverman.  You can see the twinkle in his eye:

Bernard A. Silverman, publisher of the journal article containing the  “Hydro-illogic Cycle” cartoon at the Cape Town, SA, 2006 WMO award ceremony for achievements in weather modification.  He acknowledged in that  1978 article that he was a cloud seeding advocate.
