1. Convection
Convection is the upward movement of warm air, which is less dense than the surrounding cooler air. As the warm air rises, it cools and condenses, forming clouds. When the updrafts are strong enough, they can carry water droplets and ice particles high into the atmosphere, where they freeze and become hailstones. When these hailstones fall back to the ground, they can cause damage to property and injury to people.
2. Moisture
The amount of moisture in the air also plays a role in thunderstorm development. Warm air can hold more moisture than cold air, so the warmer temperatures of summer allow for more moisture to be evaporated from the ground and into the atmosphere. This increased moisture provides more fuel for thunderstorms to develop.
3. Instability
The final factor that contributes to the increased frequency of thunderstorms during the summer is instability. Instability refers to the amount of energy that is available to drive thunderstorms. The difference in temperature between the surface and the upper atmosphere is a measure of instability. The greater the difference in temperature, the more unstable the atmosphere is, and the more likely it is to produce thunderstorms.
In addition to these three main factors, other factors can also contribute to the development of thunderstorms, such as the presence of mountains or large bodies of water, and the movement of weather fronts.
