Phase IFoundation

Background

Overview

Understanding monsoon dynamics and its changes is vital for India's agriculture, water security, disaster management, and economic planning. Climate change impacts on the monsoon are a critical area of study for policy formulation and national resilience.

The Indian Monsoon is a crucial seasonal wind system that dictates the climate and economy of the Indian subcontinent, bringing the majority of its annual rainfall. Its variability, influenced by global climate patterns and human-induced climate change, leads to significant socio-economic impacts, including extreme weather events.

Facts & tables

Key facts

Observed Changes

Recent studies show increased frequency of deep convective clouds and intense, short-duration extreme rainfall over India, with a rising trend in extreme events and a decreasing trend in moderate events over central India.

Climate Change Link

Human-induced global climate change is identified as a factor influencing regional climate and monsoon patterns, extensively studied by MoES scientists.

Research Focus

Mission Mausam aims to strengthen climate modelling, satellite observations, and atmospheric research to improve understanding of changing monsoon patterns.

Data & Analysis

NCMRWF develops high-resolution climate reanalysis datasets (NGFS, IMDAA) for climate diagnostics and variability studies, including extreme events.
