We’ve been told that the heart of a hurricane or its “eye” is usually placid and streaming with light. But scientists have found that the region surrounding the eye is swathed in the energy it produces.
Around the heart of the hurricane is a “hot tower” or a convective burst. This phenomenon is thought to form just before the storm strengthens significantly. These ferociously tall clouds may be the reason hurricanes grow stronger so quickly. When viewing photos of hurricanes, hot towers appear as heightened rain clouds reaching above the barrier around the eye of the hurricane.
Talkin’ about Another Kind of Battery Here
The powerful energy given off by the hot towers supplants excessive amounts of power in a shortened time frame, right into the center of a hurricane. This scenario gives the impression of a supercharged boost right into the hurricane’s workings. What you get is decreased surface pressure resulting in faster wind acceleration.
Fizzling Out? Don’t Think So
The manner in which the sections of air, or vortices, located in the eye convey warm, water-laden air into the hot tower may explain the hurricane’s force not being lost even when it comes across cooler waters. That excess power of the vortices keeps the storm brewing.
In the late 1950s, a physicist named Joanne Simpson argued that trade cumulus clouds were significant, and analysis using measurements were vital to understanding how the clouds drove tropical cyclones. She and her team were given the first equipped airplane, an old PBY-6A laden with instruments that measured wind motions, humidity, liquid water, air pressure, temperature and several other variables. The trip, their first, solidified Ms. Simpson’s reputation as a pioneering scientist.
Doubtful But True
Along with that success, Ms. Simpson helped move meteorology in a new direction by revealing a process by which energy brought about by the condensation of water inside tall, rhombus-shaped, cumulonimbus clouds gives off the energy required to sustain the Hadley circulation and keep the trade winds blowing. This was called the “hot tower hypothesis”. It was not well-received, yet Ms. Simpson was able to further show that this hot tower of transferred energy is plausible and that it comes to pass continuously in equatorial regions.
