Question

short note on variation in rainfall​

Answer 1

Answer:

Rainfall Variability. The degree to which rainfall amounts vary across an area or through time is an important characteristic of the climate of an area. This subject area in meteorology/climatology is called "rainfall variability." There are two types (or components) of rainfall variability, areal and temporal.

Both temporal and areal variability of precipitation may be measured in various ways. The resulting numerical value can be used to characterize the climate of a region in various ways.
