Tropical Storm / Hurricane / Tropical Storm Isaac is gone, but it generated numerous tornadoes along the East Coast; from Florida to the Carolinas, in Alabama, Mississippi and Louisiana. In my area of Northwest Florida, there were many public reports of tornadoes on Tuesday, Wednesday and Thursday. Unfortunately, the large majority of these tornadoes were never reported to the proper authorities. This creates a huge problem for everyone.

Guessing where a hurricane is heading is not an exact science. Those predictions are much better today than in the past due to better hurricane modeling. Via television, everybody can get constant updates on The Weather Channel. As Tropical Storm Bonnie approaches the oil drenched areas of the Gulf of Mexico, I wanted to share a few Internet sites I visit to quickly get an idea about what is going on and, if I have time, some fun.

Why
Rocco Calaci

Why do people forget that the atmosphere reacts to weather changes at all levels besides the standard heights of 1000, 925, 850, 700, 500, 300, 250 and 200 millibars? If someone doesn’t evaluate the entire column of air at all levels, how can an accurate analysis be performed? How can you trust algorithmic results from incomplete data?

We Are Using the Wrong Ruler
Rocco Calaci

Whenever a hurricane strikes a community, we obsess over the maximum wind speed and storm surge depth. In my last blog, I mentioned many other weather elements within a hurricane that can cause damages. Now I want to speak my mind on how we need to look at hurricane damage from another perspective.

Is a hurricane only wind and water? (Part 2)
(Rocco Calaci)

Besides mesocyclones, there were numerous microbursts during Hurricane Ike. A microburst can best be described as strong downward (vertical) winds that result from a strong thunderstorm cell collapsing. The outflowing wind pattern is omni-directional, creating an elongated horizontal vortice along the leading edge of the winds.

This diagram obtained from the Internet (generated by the 45th Weather Squadron, USAF) depicts the wind pattern of a microburst as it hits the ground.
