How are storms formed?

Answer

Storms are formed when several different prerequisites are met; there must be an abundant amount of moisture in the air, the presence of electrical charges in the area and a high temperature. These factors not only help the formation of a storm, but as they become more accentuated, the storm has the capacity to become more powerful. For these reasons, there are different areas that are more susceptible to storms.

A thunderstorm is rain that has some level of thunder and lightning present, according to the National Severe Storms Laboratory. They can range in severity from mostly harmless to very dangerous. There are several different factors that contribute to the formation and severity of a storm and can be used to predict them.

Moisture, or water in the air, is required for storms to form. This is why storms are more frequent in the summer and spring months and in areas that are more naturally wet. The process of air rising and bringing moisture with it contributes to the formation of storms. Heat helps this process because it facilitates the rising of the moist air to where it condenses into a storm. As it gets higher, the concentration of moisture rises as well. Eventually, the water condenses, and rain begins. If there is also the presence of electrical charges in the area, the forming storm can become a thunderstorm.

Ask.com Answer for: how are storms formed
The action of warm air rising and cold air sinking (convection) plays a key role in the formation of severe thunderstorms. If the warm surface air is forced to rise, it will continue to rise, because it is less dense than the surrounding air.
Two of the most important ingredients for thunderstorm formation are instability (unstable air) and moisture.
