Rainy season occurs because of changes in wind patterns that bring moisture-laden air over land. Here's a breakdown of why:
The rainy season, particularly in regions like India and Sri Lanka, is triggered by a combination of factors related to ocean temperatures, wind direction, and condensation.
- Evaporation from Warm Water: Warm water in the ocean evaporates, turning into water vapor and rising into the air.
- Changing Wind Direction: This evaporation influences wind patterns, causing the wind to shift direction and blow towards the land. The wind carries the moisture from the ocean.
- Moisture Blows Toward Land: As the moisture-laden wind blows towards the land, it brings a significant amount of water vapor.
- Condensation and Rainfall: When the warm, moist air rises and cools, the water vapor condenses into clouds and eventually falls as rain. This leads to extended periods of humidity and heavy rainfall, lasting for months.
In summary, the rainy season is a result of warm ocean water evaporating, causing winds to change direction and carry moisture-rich air over land, where it condenses and produces heavy rainfall.
