Dr. Suppresso

The tropical Atlantic remains quiet. A non-tropical low pressure system off the coast of North Carolina today is expected to intensify and move northeastward this week. This low should remain non-tropical, but could gain some tropical characteristics and give Nova Scotia heavy rain on Friday. None of the computer models are forecasting any tropical storm development in the Atlantic this week, and the flow pattern reminds me more of November than October.

Interview with Hurricane Specialist Dr. Jack Beven
With hurricane season winding down, it's time to pay tribute to the forecasters at the National Hurricane Center that have done such an excellent job over the years. You've seen the familiar signatures at the bottom of the National Hurricane Center advisories--Avila, Beven, Stewart, Franklin, Pasch, and Knabb (and this year, joined by five new names!) It's these hurricane specialists that form the bedrock of the superb NHC hurricane forecasts. They are fantastic at what they do, and I rely heavily on their expertise. I'll be doing profiles of two of the forecasters this hurricane season, so you can see the faces behind the names.

"Beven" is Dr. John L. Beven II, one of the six senior hurricane specialists at the NHC. Jack, 45, has been working at the Hurricane Center since 1988. He started then as an intern while working on his Ph.D., and landed one of the coveted hurricane specialist jobs in 1993.

Jack graduated in 1984 from Louisiana State University with a Bachelor's in Physics. He got his Masters degree in Meteorology in 1988 from Florida State, and continued on for his Ph.D. in 1994. His advisor was Dr. T.N. Krishnamurti, famous for his numerous research achievements in tropical meteorology, including development of the FSU Superensemble tracking model for hurricanes. Jack's Ph.D. thesis was titled, "Tropical Cyclone-Environmental Interactions During Recurvature - A Modeling and Observational Study".



I got a chance to catch up with Jack this April at a conference in Monterey, and asked him a few questions:

Q:What is your most memorable experience with a hurricane on the ground?

A: Well, back in 1985 while I was in graduate school at FSU, Hurricane Kate came ashore. A bunch of us grad students found a place by the west door of the Love Building sheltered from the wind, and took turns running into the wind.

Q: What do you do in your free time?

I like to go storm chasing! I take a yearly trip out to Oklahoma and chase tornadoes. I'm also a big Dr. Who fan, and enjoy sports, particularly college football, college basketball, and college baseball.

Q: Do you have any comments you'd like to make about the global warming issue?

A: I think there's a lot of room for both natural and man-made effects in the current way the climate is changing.

Jack has the nickname "Dr. Suppresso" among his storm chaser friends, thanks to the tendency for promising supercell thunderstorms to suddenly die out when he approaches--or for an expected outbreak of severe thunderstorms to completely fail, due to a strong capping inversion. With that kind of ability, we need to have him intercepting hurricanes at the coast, instead of writing advisories!

OK gotto go to work now the correct answer is...

The answer is (b); the ball will float higher out of the water after the mineral spirits is poured onto the water.
The ball floats at a higher level because the mineral spirits in which the upper part of the ball is floating provide an additional buoyant force on the ball. If the ball is floating on water alone, the top part of the ball is immersed in air, which has a much smaller density.

Thanks to all who participated...
Nash and Ricderr and cbbeachbum got the correct answers...smarty pants.

Its been a long time Gatorx, but I will give you an answer after coffee..LOL Yes, for an undergraduate degree in Meteorology you have to take two semesters of Physics.

I noticed that Dr. Beven in Dr. Masters blog has his degree in Physics...I wonder if most meteorologist have that as an undergrad degree...for those of you that think physics is not weather related perhaps you would care to read Dr. Masters above post.

One of the strange tings that was found after Katrina here was hundreds of black rubber balls. As inquireing minds often drive ambition reasearch found that the pile of crushed concrete from our old grain elevator had these balls in it to help in the solidtation of the concrete when it was poured due to the Monolithic pour of its nature.
