Short Summary

This chapter introduces the complex subseasonal variability of the Indian Summer Monsoon (ISM), highlighting the role of intraseasonal oscillations in driving active and break spells and their impact on rainfall distribution and extreme weather events across the Indian subcontinent.

Objective

• To provide an overview of the subseasonal variability of the Indian Summer Monsoon, focusing on the mechanisms and impacts of intraseasonal oscillations, and setting the context for its prediction and associated extreme weather events.

Study Configuration

• Spatial Scale: Indian subcontinent, including central, southwestern, northeastern, and southeastern regions of India.
• Temporal Scale: Subseasonal (1–60 days), encompassing synoptic (1–7 days), quasi-biweekly (10–20 days), and low-frequency intraseasonal (30–60 days) modes within the June to September (JJAS) monsoon season.
