Who founded the University of Oklahoma's School of Meteorology, and when did this occur?
Since I do not attend OU, I take a guess at the year.
1960 is when OU meteorology program was established.
1960 first meteorology courses offered at OU
1963 first meteorology degree awarded.

Wait a second... what about Guam??
Typhoon Paka has ripped through the island of Guam, causing an estimated $ 200m in damage. Thanks to accurate predictions of its path, however, and efficient evacuation procedures, no deaths have been reported. More than 50 pregnant women had been taken to Guam Memorial Hospital, since the pressure from the storm can induce childbirth in women who are seven or more months pregnant. Nine of them did give birth during the storm.
Local weather stations were out of action after power failures, but a station in Honolulu confirmed a maximum gust of 236mph (380kph) which is the highest wind speed ever recorded. The previous high of 231mph was measured on Mount Washington on 12 April 1934.
The Independent (London), December 19, 1997,
What term was used to define a "wall cloud" before the term "wall cloud" became popular?
Which cloud is the announce of the evolution between cumulus congestus and cumulonimbus? .
I hate to picky but isn't the distinction beween cumulus congestus and a cumulonimbus the initial glaciation of the updraft into an anvil (which implies charge separation).
The cap cloud (Pileus) is just that - a cap cloud - which, IIRC, is a cap of supercooled condensation associated with the rapid displacement of air above a rapidly growing cumulus tower in a sufficiently moist layer.
seiches (sp?)...?
I suppose no one is going to get this, and I don't want this thread to die, because it is fun. The answer can be seen in a newspaper clipping from my private collection of tornado stuff:
How can you expect someone to know that kinda stuff? This should be a weather trivia, not a quiz about people.
To answer Sam's question and to add to Mike's answer, it was Yoshi Sasaki.
Although some people do mistakenly use "collar cloud" as a synonym for "wall cloud" - the collar cloud is something entirely different. The synonym I'm looking for is actually still in use today - although it is quite obscure. Any guesses?
Damnit :!: LOL :lol:
Guess I will ask a question now... This is a term I learned from The Weather Channel way back in the day...

Looks like a shelf cloud. The lowered area could be easily mistaken for a wall were it sloping into the darker area of the photo, and one could determine what the darker area is.
On the evening of May 24, 2004, we saw many wall look-alikes on the leading edge of the line that eventually hammered Beatrice, NE while watching from our second floor window in the Super 8. Weather Practice::

Scud is a term that chasers have used for a long time. What does scud actually stand for? (hint, scud is actually an abbreviation)
"Scud" may be used as an acronym by chasers now, but I'd bet all the money I have that it did not originate that way. In fact, I'll bet that someone decided to make an acronym out of it only within the last 20 years or so, while it's been a word for a lot longer than that.

I should probably also say that for updrafts that do not glaciate (i.e. remain cumuliform) I would make the distiction between cumulus congestus and cumulonimbus being when either the Equilibrium Level is reached/surpassed and/or charge separation has occurred and the cell is electrified.

Sorry, I didn't see that one there. I'll take a guess and say the answer is a storm surge - though I have never heard of such a case. If that is the case, would the "storm surge" be driven by strong outflow as opposed to extreme the low sfc pressure induced storm surge in hurricanes?

We continue with a another question?
scattered cumulus under deck
Okay, this one is kinda easy, but here it goes.... who was the ONLY meteorologist to ever appear on the cover of Time magazine?
What does DPVA mean?
Mike
A little interuption and defense of Mount Washington. After all, I am an intern at the observatory. I'm headed back up for another week on the mountain on Wednesday.
Of course, Mount Washington does have the highest recorded wind speed, 231 mph. Yes, for a few days Guam took the record but it was found that their anemometer was terribly inaccurate. They actually used a thermal device to measure the wind speed. Speed was determined by how quickly the device cooled down. It was never properly calibrated, especially with all that rain.
Back in the day they guys on Mount Washington were using a modified cup-style anemometer. They counted the clicks it made as it rotated around. Today, we use a static pitot anemometer. It is just a modified airplane pitot. The wind pushes on a column of water and we determine the wind speed based on the height of the column. Earlier this month we peaked at around 150mph. We have extreme icing conditions and the primary pitot went down during the storm from ice. So we had to manually hold the backup pitot in the wind. That was fun! Our best guess is the winds were higher as the backup pitot could not be held as high as the primary, plus we could only hold for a few minutes an hour.
Sorry, about the interruption. If anybody has any questions about the weather or life on Mount Washington please send them my way.
I believe that Carl-Gustaf Rossby is the correct answer.

I suppose both Mike and Laura should each get to ask a question now, as your collaboration led to the correct answer: Yoshi Sasaki in 1960.
Good Job, Guys!
Hi Patrick! I think you make a valid point. Pileus clouds don't really tell you that the cumulus congestus will transform into a cumulonimbus. It's just a cap cloud. I think the cloud that should tell you when a cumulus congestus reaches cb stage is when it starts to glaciate, forming an anvil. I don't think pileus will tell you for sure that the cumulus congestus will transform into a cb. I guess it would be a sign that it is growing, but I have seen pileus caps on towers that never did end up glaciating.
Scud is a term that chasers have used for a long time. What does scud actually stand for? (hint, scud is actually an abbreviation)
This scientist was one of the first to suggest that lightning played a roll in the formation of life on earth.
Very good Jeff. Your turn to shoot us a wx question! 8)
I'm going to say collar cloud, but that's a guess...
One of my all-time favorite weather books, the author is John Fuller, who, according to his blurb, is from right near my home town of Westport, Connecticut.
So, someone ask the next question already - so much of this is going to come down to who is at their computer when the question comes up. Maybe there should also be a rule that you can't look up the answer on the web - but books are OK?
Pileus
After realizing that the answers to most of the trivia questions were easily available on the internet, I wanted to go for something devilishly obscure :lol: . I'll be very surprised if anyone gets this.
Name the 18-year-old from Montgomery, Alabama who was in critical condition after a tornado threw him off his motorcycle on Sunday, November 25th, 1979 (this was an AP news release).
Would that be a hail spike, caused be none other than... hail?

Laura, I agree that any glaciated anvil is certainly a CB. The reason I made my second post was that I forgot to add that one should also consider that many (most?) supercells have unglaciated cumuliform anvils and cumuliform overshooting tops (and certainly anvil "knuckles" are unglaciated). In such situations I take it that the cloud matter is still supercooled condensation and these are also certainly CB and not CC (i.e. I take the delineation between CC and CB as the arrival and spreading of convective condensate at the EL and/or having evidence of charge separation).
And yes, the Cap Cloud results from the rapid displacement of air associated with the convective process.
Next question:
What, where, and when was the strongest wind gust ever reported?
 How much does getting a small tattoo on your hip/stomach hurt?
 Do anyone else have an itchy anus? ?
