Thunderstorms form when rapidly rising warm air brings moisture to higher parts of the atmosphere, then water vapor cools and condenses into droplets that fall to the Earth as rain. The process of rising warm air is call... More »

Thunderstorms originate in cumulonimbus clouds. Warm, humid air rises then cools, creating moisture to form the cloud. Thunderstorms produce heavy rain, strong winds and sometimes hail. More »

A thunderstorm is a storm with heavy rainfall accompanied by wind, thunder and lightning. These storms occur when air that is moist and close to the ground heats up and rises to form cumulonimbus clouds that produce prec... More »

Tornadoes form out of thunderstorms, where moist air rises, cools and condenses into clouds that release heat and force cooler air back down. If the updrafts are strong enough, the feedback loop forms an air vortex that ... More »

The Coriolis parameter is a postulate that explains the forces acting on objects, such as a fixed volume of air, as it moves through the atmosphere of a spinning Earth. The equation describing it takes into account the r... More » Science Earth Science

The sun provides the Earth with energy in the form of heat, which it uses to warm the Earth's surface, oceans and atmosphere. The heat energy found in the atmosphere is one of the major components of the Earth's climate ... More »

Precipitation occurs when water-laden air cools, causing the water to condense back into its liquid form and fall as rain. In order to acquire the water in the first place, warm air must flow over a body of water. When t... More »
