What is the Accumulation of Rain?

Rain accumulation refers to the total amount of rainfall measured over a specific period, typically in inches or millimeters. This parameter is a crucial input into understanding the volume of water added to reservoirs, soil moisture levels, potential flooding risks, or whether to take actions as simple as deciding to water a lawn. This measurement is given for the amount of precipitation that has accumulated over the hour before the specified time. 

What is the impact of the Accumulation of Rain?

Significant rain accumulation can lead to flooding, impacting agriculture, urban infrastructure, and water management systems. In contrast, low accumulation levels over extended periods can indicate drought conditions, affecting water supply and ecosystem health.
