Thunderstorm Sounds APP
Thunderstorms are caused by rapid upward movement of warm, humid air, sometimes along the front. However, some sort of cloud effect is needed, whether it is a trough forward or a short wave, or some other system for the air to accelerate rapidly upwards. As warm, humid air moves upward, it cools, condenses, and forms a cumulative cloud that can reach a height of more than 20 kilometers (12 miles). When the rising air reaches the dew point temperature, the water vapor condenses into water or ice droplets, reducing the pressure locally in the thunderstorm cell. All precipitation falls at long distances through the clouds to the earth's surface. When the drops fall, they collide with other drops and become larger. The falling drops create a descent that draws cold air with it, and this cold air spreads over the earth's surface, sometimes causing strong winds that are usually associated with thunderstorms.
