Rainfall from June 1 to June 12 measures 4% lower than the long-term average
From June 1st to June 12th, rainfall was 4% below the long-term average. The Long Period Average (LPA) represents the average precipitation over a span of 30 to 50 years, aiding in more accurate forecasting by mitigating fluctuations in rainfall across regions and timeframes.
What is Long Period Average Rainfall?
The Long Period Average (LPA) signifies the mean volume of rainfall observed across a designated area throughout a specified timeframe, typically a month or a season.
About
LPA represents the average precipitation levels aggregated over an extensive duration, commonly ranging from 30 to 50 years.
Significance
Given the substantial variations in annual precipitation among regions, months, and even within the same geographical area or timeframe, the LPA serves to mitigate these fluctuations, facilitating more reliable forecasting.
