Cosmic Raindrops Scan to Help Meteorologists


NASA experts for the first time managed to obtain 3D images of rain drops inside thunderclouds via satellite. It turned out that all the drops have different sizes, the largest of them are located in the center of the cloud, and small ones are on the edges. Monitoring the distribution of drops will make weather forecasts more accurate.

In the 3D images droplets of 0.5-3 mm are indicated as blue, and 4-6 mm are yellow, orange and red. Analyzing this data, scientists can determine how long the storm will last and how much precipitation will fall, which will help prepare for possible floods. It will also be possible to determine the strength of the coming storm, as the fine droplets quickly evaporate, cooling the air, and it often causes damaging winds.
