1. A wind system that influences large climatic regions and reverses direction seasonally is known as a monsoon.
2. The Bermuda High and thermal lows.
3. Fresh rain and clean roads
4. Traffic jams and bloked roads
5. Flooding happens a lot in India but it often causes deaths and loss of property. Many of the neighborhoods are now destroyed after a drought that had badly damaged their crops.
6. I honestly think it depends on the region. If the region is in drought, it should definantly have a monsoon but if it's always raining there, it doesn't need a monsoon.
