January 30, 2013. Storm named "Villingen" stirs the vast Indian Ocean near the tropical island Madagascar. NASA satellite image shows that the cyclone has a very warm heart, which boils intense storm activity.
Satellite "Suomi" caught "Villingen" night Jan. 28 northeast of Madagascar. The photo shows a very low temperature at the tops of thunderstorm "towers" (? 103 ° C). You can also see interesting atmospheric gravity waves that propagate through the storm.
Pop-up "bubbles" of hot air penetrate the tropopause, where cool and melt into a giant dome, very resembling a blacksmith's anvil. This scenario requires a lot of energy, as is usually the vertical growth of clouds stops just at the level of the transition layer between the troposphere and stratosphere.
Meteorologists say that cyclone greatly intensified over the previous day. January 29 at 10:15 GMT satellite "Aqua" took a picture of him in his prime, when abounding thunderstorms tightly twisted spiral cloud was in the center of the eye is slightly tucked in a diameter of 41 km. Maximum wind speed was estimated at 167 km / h
A tropical cyclone is confident approaching the island of Madagascar at 15 km / h It is assumed that the storm will turn to the south, and continuing to grow, will move parallel to the east coast of Madagascar.
