Atmospheric convection is the process by which warm air rises and cool air sinks in the atmosphere. When the sun heats the Earth's surface, the air above it warms up, becomes lighter, and rises. As this warm air ascends, it cools down, leading to a cycle of movement that helps distribute heat throughout the atmosphere. This process is essential for weather patterns and can lead to the formation of clouds and storms. Convection currents play a significant role in tropical storms and thunderstorms, as they help transport moisture and energy, influencing local and global climates.
