What is thunderstorm?process of formation

Warm, moist air near the ground begins to rise due to convection (e.g., from solar heating). As this air rises, it cools and the water vapor within it condenses, forming cumulus clouds. The condensation releases latent heat, which further warms the air parcel, making it more buoyant and enhancing the updraft. During this stage, there is primarily upward movement of air, and usually no precipitation or lightning.

The updrafts continue to strengthen, causing the cloud to grow vertically into a towering cumulonimbus cloud. Water droplets and ice crystals within the cloud grow larger. When they become too heavy for the updrafts to support, they begin to fall as precipitation, creating downdrafts. At this stage, both strong updrafts and downdrafts coexist within the storm cell. This is the most intense stage, characterized by heavy rain, strong winds, frequent lightning and thunder, and sometimes hail.

The downdrafts become dominant and spread throughout the storm cell, effectively cutting off the supply of warm, moist air that fuels the updrafts. Without the continuous supply of rising warm air, the storm loses its energy source. Precipitation begins to weaken, and the cloud gradually dissipates as it loses its structure and evaporates.
