How do violent storms form?

Answer 1

That depends on the type of violent storm. Tropical cyclones develop are a result of clusters of thunderstorms, called tropical disturbances, gaining energy from the moisture that evaporates from warm ocean water. The storm cluster intensifies and organizes as a result. Severe thunderstorms usually develop in an unstable, warm, moist air mass. This air may be lifted by the advance of a cold front or dry line, which triggers the storm development. Wind shear alters the manner in which air flows in these storms such that they do not "choke" on their own rain-cooled air. Severe wind gusts in these storms usually occur when masses of rain-cooled air, which are denser than their surroundings, descend rapidly and spread out at ground level. Tornadoes usually develop from a special type of severe thunderstorm called a supercell. In these storms, in addition to the previously mentioned effects, wind shear sets them rotating. In some cases this rotation can tighten and intensify to form a tornado.

Answer 2

Violent storms, such as hurricanes and tornadoes, form when warm, moist air rises rapidly and interacts with cooler air. The rotation of the Earth and other atmospheric factors contribute to the development and intensification of these storms. As the storm system grows in strength, it can produce strong winds, heavy rainfall, and sometimes hail or tornadoes.
