In such thunderstorms prevail strong updrafts. That's why ? that showed the radar recordings? The smaller raindrops that formed in the lower layers were carried upward. During the climb, they came across "oncoming traffic". Because the frozen larger drops, which were formed higher up, fell down because of their weight. Due to the friction of the two types of droplets together electrical charges were separated, which eventually caused lightning.
The task of this NASA flight was to collect supplementary data on the measurement results of the TRMM (Tropical Rainfall Measuring Mission) satellite. The tropical thunderstorms are of particular interest to the scientists because they transport considerable amounts of heat into the upper atmospheric layers. This maintains the temperature gradient between the tropics and the poles, which drives global wind circulation.Axel Tilleman's ad
