The monsoon season is a weather phenomenon characterized by a shift in wind patterns that brings heavy rainfall to certain regions. Monsoons typically occur in tropical and subtropical areas, and are caused by temperature differences between land and sea. This seasonal rainfall is vital for agriculture and ecosystems in affected regions, but can also lead to flooding, landslides, and other hazards. Scientists study monsoons to better understand their patterns, variability, and impacts on various aspects of society and the environment.
