Rain

Rain is one of the most common forms of precipitation and plays a vital role in Earth’s climate, agriculture, and water supply. It occurs when water vapor in the atmosphere cools and condenses into droplets inside clouds. Once these droplets become heavy enough, gravity pulls them to the ground as rain.
 

According to the India Meteorological Department (IMD), rainfall is measured in millimeters or centimeters through a district-wise monitoring system that tracks daily, weekly, monthly, and seasonal rain across the country. The IMD also provides rainfall maps, analysis, and forecasts to help monitor changing weather conditions.


Not all falling water is classified as rain. Rain consists of liquid droplets usually larger than 0.5 mm in diameter. Smaller droplets are called drizzle, while frozen forms such as snow, sleet, or hail are categorized separately. Raindrops can range from 0.5 mm to about 9 mm before they begin to break apart.


Rain is classified by both intensity and duration. Light rain produces little accumulation, while heavy rain can trigger flooding and waterlogging. Rain may also occur as short bursts called showers or as continuous rainfall lasting several hours or days.


India’s monsoon rainfall is measured against a Long Period Average, which helps meteorologists determine whether rainfall is normal, below normal, or above normal in a season. Rain remains central to India’s economy, especially for farming, groundwater recharge, and drinking water supply.
