Why in the news?
- IMD noted that India received the highest rainfall in August 2020 since 1926. India received 32.7 cm rainfall in Aug 2020 which was almost 27% more than normal rainfall.
- The reason for huge rainfall was found to be long-lasting low-pressure systems, or rain-bearing winds, that formed in the Bay of Bengal and were vigorous enough to travel all the way from the south-eastern coast up to north-west India.
- Long periods of heavy rain followed by extended dry periods are a feature of climate change and are part of a general change in monsoon patterns over India.
