Cumulus congestus cloud grows into a Cumulonimbus over Sutherland Heights! 0.45 inches falls in 20 min after transformation!!

Also, I am also posting way below a new (!) not-previously-published. but rather rejected- by-important-scientists-a-long-time-ago-manuscript FYI!

Very exciting! (Hah!)

Its published now, though, isn’t it???!!!

“Online.”

Its about science and how it works, and how it has failed;  examples given.   I put it down toward the bottom of a normal blog because I am shy.

Clouds from a few days ago, August 26th, now that the “choke point” in uploading photos to Word Press  has been, at least temporarily ameliorated.

Here’s the sequence as a great cloud bottom drifted toward us from Pusch Ridge on the afternoon of the 26th.  If you saw this coming, you should have been clearing channels around the house for excessive water flow.  I forgot to.

Unloaded 0.45 inches at this site. 1.69 inches up on there on ol’ lady Lemmon. We sure needed this dump! Below, one of the great cloud bottoms of our time, that of a Cumulus congestus cloud, filled, as we say here, with rainy portent (maybe hail, too):

1:44 PM, August 26th. Note just a tinge of shading on the right side. First drops, the biggest ones, or even hail stones are just coming out.
Attachment1
1:48 PM. Cloud beginning to bust open with rain now; updraft collapsing over there. Now its a Cumulonimbus.
Attachment2
1:53 PM. Nice shafting over there, but will the  cloud base overhead now split open  over us?
1:54 PM. Looks really good almost overhead toward Saddlebrooke! Just don't unload after you go by!
1:54 PM. Looks really good almost overhead toward Saddlebrooke! Just don’t unload after you go by!  Note scruff of lower cloud (called, “pannus”) caused the the outflows of storms to the SW of Catalina.  Not long enough really to be a “arcus” cloud, but clouds like this are almost always associated with a shift in the winds that helps build clouds overhead by acting like a micro-cold front, the rain-cooled air lifting the warmer, humid air ahead of it, and some of that warmer air being cooled to its condensation point producing these lower shelves of cloud.
Attachment 3
2:07 PM. The height of the storm, the visibility down to a hundred yards or two is all. This particular intense period hardly lasted a couple of minutes before it let up noticeably.

Update alert for the posting of new (!) not-published rejected items by this Arthur:

The Cloud Seeding Literature and the Journal Barriers Against Faulty Claims:  Closing the Gaps

(the original title, submitted first in 1997), final rejection in 1999 (Bull. Amer. Meteor. Soc.)

The reviewers, Harold O., Danny R., and someone named “Anonymous Reviewer B”, guessed as, “”B”, for “Bernie S.”

Those in the cloud seeding culture don’t need the names spelled out.  Harold O. is part of the “old guard” cloud seeding culture, while Danny R. is part of the new cloud seeding guard, one that has gone on to be a science superstar since his early work at the Hebrew University of Jerusalem under the leader of the Israeli cloud seeding experiments.   He  did some work there on the clouds of the Mediterranean and satellite interpretations of them (available in Hebrew only the last time I checked).

While Danny R was there during the time of the reporting of the benchmark Israeli 2 randomized experiment by the leader of the experiment  (1976-1986) he himself was not involved in those (ultimately flawed) analyses.  Later, he participated in the unraveling of the 2nd experiment with Israeli statistician, K. Ruben Gabriel in 1990, J. Appl. Meteor.  Half of the 2nd experiment’s results had been previously omitted, an omission which produced an apparent, unambiguous “confirmatory” success of the Israeli 1 experiment, for the short of it.

The 1990 development in Israel, in essence a retraction of what everyone thought was an unambiguous cloud seeding success, plus the fall of the equally important, earlier benchmark randomized experiments in Colorado, at one time also claimed to have proved cloud seeding by the National Academy of Sciences (Malone et al 1973),  were the primary reasons for composing the piece being posted today.  You may also know that your very own Catalina  “cloud-maven” was in Israel in 1986 for 11 weeks, in doubt of those “hard-to-rain” clouds that were being described by the leader of those experiments, resulting in “Rain from Clouds with Tops Warmer than -10° C in Israel”, (1988, Quart J. Roy. Meteor. Soc.).  This was to some degree the first crack in those experiments.  (Of course, I would say that!)

How could such glowing,  but ultimately critically flawed journal papers appear ultimately involving hundreds of journal pages?  What went wrong with peer reviews?

I attempt in this piece to describe in this piece how science is supposed to work, and these pretty amazing chapters of science in cloud seeding,  and offered some possible solutions.

At one time, Prof. Peter V. Hobbs, named to write up a status piece on Clouds-Climate for the World Meteorological Organization (WMO) in 2003 or so, was going to use the “rise and fall” of the Colorado and Israeli experiments  in this piece I have just posted.  He was going  to demonstrate how we scientists can think we have proved something,  but upon closer inspection, find that we have not proved at all!

Peter Hobbs was concerned that the then many unknowns about clouds were not being treated properly in climate models (being parameterized too crudely), and therefore those parameterizations of clouds in climate models could  lead to erroneous conclusions concerning the amount of global warming that might be ahead.

In his take on this MS, and that “rise and fall” section in particular, Peter, who was not one to dole out compliments very often said of it, “This is pretty good.”  Peter had not reviewed it beforehand.

Ultimately, Peter contracted pancreatic cancer and was unable to submit his status summary to the WMO.

  1. Hi, Art! Nice web site. I will read your newly published paper there. Things are mostly okay with me. Just some health problems. But I’m happy. I hope you are doing well, too. I’m living in Boulder (since 1984!). I’ll put my name on your mailing list. We can talk more later. Wow! Nice to see this from you. I can’t wait to talk.

    My “website,” written by me, obviously, in html, is for my math tutoring, which I’m not really doing any more. It won’t be up much longer.

    1. Wow, how great it is to hear from you, Tom, one of my favorite people in our group! I just now saw this, belatedly, as seems to happen more and more. Brain dimming, as I often say.

      Its so great to hear that you’re “mostly OK”, but being “happy” is the best part. I guess me, too, “is mostly happy.”

      Thanks for that link to your website, too. Will check it out as they say, and will e-mail you right after this.

      Well, of course, that paper wasn’t new, but a very old text, cuneiform maybe by now. Have thought about posting the reviews and rebuttals, but then, that would overwhelm all but the MOST interested in that long ago battle.
