The South Asian monsoon is a seasonal weather pattern that brings heavy rainfall to countries like India, Bangladesh, and Pakistan. It typically occurs from June to September, driven by the temperature difference between the land and the ocean. This shift in temperature causes moist air from the Indian Ocean to move inland, resulting in significant precipitation. The monsoon is crucial for agriculture in the region, as it replenishes water supplies and supports crop growth. However, it can also lead to flooding and landslides, causing damage to infrastructure and communities. Understanding the monsoon is essential for managing its impacts on society and the economy.
