The Tropics Heat Up - Along Comes AL97


The tropics are starting to heat up. AL97, a disturbed area of weather north NW of Puerto Rico, is providing some excitement here and at the NHC, and while this morning it doesn't look too interesting, folks in Miami are warily watching it. The latest forecast tracks, seen to the left, leave no doubt about where it is headed - the only question is whether it will be a named strom by the time it gets there on Friday. Hopefully nothing serious develops since Friday is the day I return from Tampa to Miami and we prepare for our trip to Wisconsin next Monday.

At present AOC has been tasked by the Hurricane Center to begin flying its G-IV jet this afternoon at 1:30 pm on a track that is shown here. This will be about an 8 1/2 hour flight at altitudes from 41,000 ft. to 45,000 ft. AOC personnel will be dispensing GPS droopwindsondes at each of the points shown. These devices fall on a small parachute to the surface and radio atmospheric data back to the aircraft for processing and immediate transmission from the aircraft. The profile data (temperature, humidity, pressure and winds) are then utilized in a number of the forecast models used to predict the track of the storm. Since I covered this ground in my 2008 Blog, you may want to link back to it for a wealth of information on our facility, its aircraft and personnel. Just click on the month and posting in the right panel ts, hat may be of interest. The blob starts with the latest posting in that year and works back to the first one in May. For blow-ups of most of the picture and diagrams, just click on them. Remember to hit your back button to return to the blog.

I had promised to talk to you about AL96, but it didn't amount to anything even though we did fly research missions into and around it with one of our P-3s and the G-IV. Hopefully AL97 will have the same fate. More on that later.
