Precipitation
Precipitation encompasses various forms of water released from clouds, such as rain, snow, and hail, each with distinctive characteristics. India experiences substantial seasonal rainfall primarily during the Southwest Monsoon, highlighting the regional variations across the country. Measurement techniques like rain gauges are crucial for consistent data on precipitation patterns, which inform infrastructure planning, hydrology, and agricultural practices.
