Answer 2

These disturbances bring heavy rainfall and snow to the areas.

• The phenomena deliver moderate to heavy rain to low lying areas and significant snow to the Indian Subcontinent's hilly highlands.  
• They are responsible for the majority of rainfall in the northwest area of the country.
• Crop damage, landslides, frequent floods, and avalanches can all be caused by excessive precipitation caused by it.
• It also brings chilly waves and dense fog to the Indo-Gangetic plains.  Until another disturbance occurs, these possible circumstances stay steady.
