About Long Period Average (LPA) of Rainfall:

  • LPA represents the average rainfall measured over a specific area for a defined duration, typically spanning several decades such as 30 or 50 years.
  • This metric serves as a reference point for predicting the expected amount of rainfall in a particular region for a given month or season.
  • The India Meteorological Department (IMD), responsible for monitoring rainfall across the nation, establishes this rainfall norm using data accumulated over 50 years. It undergoes periodic updates approximately every decade by integrating the latest information from rain gauge stations.
  • Presently, the LPA for the entire country’s southwest monsoon rainfall, based on data from 1971 to 2020, stands at 868 cm.
  • Historically, IMD has computed LPAs at 88 cm for the period 1961-2010 and at 89 cm for 1951-2000.
  • Nationally, the annual LPA has experienced a marginal decrease from 117 cm to 116 cm.
