El Nino & major crops

On Thursday, IMD assigned 33% probability to below-normal rainfall and ~ 25% probability to deficient rainfall this year due to El Nino. Monsoon rainfall is likely to be 95 per cent of the normal with a margin of plus- minus five per cent error. One thing about El Nino is that all El Nino years are not drought years but all drought years are El Nino years 

India witnessed droughts in 2002, 2004 and 2009 and El Nino. A strong El Nino can cause droughts in India, Southeast Asia and Australia and heavy rainfall in other parts of the world like the US and Brazil.
