The Asian summer monsoon is a large-scale weather system that brings heavy rainfall to the Indian subcontinent and Southeast Asia during the summer months. It is characterized by a shift in wind patterns that bring moisture-laden air from the Indian Ocean to the Asian landmass, resulting in intense rainfall and often flooding in the region. The monsoon plays a crucial role in the agriculture and economy of the affected countries, as well as influencing regional climate patterns and even global weather systems. Researchers study the Asian summer monsoon to better understand its variability, predictability, and impact on society, as well as its connection to larger climate phenomena such as El Niño and global warming.
