What causes week or below average monsoon in India ?
Plz answer fast

Dear Student,

a. EL Nino is the event where the waters of the tropical central and Eastern pacific become warmer than normal. This has the effect of increasing rainfall in this general area, but over the Western Pacific air pressures tend to increase and suppress rainfall thus it is typically drier than average in that region.
b. El Nino in India makes Monsoon weak, and kills it.
c.  El Nino weakens the trade winds, may even lead to reverse wind direction that allows the warmer water from the western Pacific to flow toward the east. 
d. Shift of warm waters from eastern south Indian ocean may impact the rainfall in South east Asia.
