CHENNAI: Basic difference

The existing models, including the one developed by the IMD, can accurately predict the onset of the southwest monsoon over Kerala

The new method proposed by the German scientists can predict both the onset and withdrawal of monsoon over central India

The new one uses air temperature and relative humidity unlike current methods

 

Spot on

May 6: researchers predict monsoon will hit Telangana on June 10 +/-  4 days

June 8: monsoon hits Kerala, will reach Telangana on Friday 

 

Ghats, North Pak link

As per the German approach, Eastern Ghats in Central India and North  Pakistan serve as “tipping elements” in more accurately predicting the arrival and departure of the southwest monsoon

Cyclonic circulations start in the Eastern Ghats as a local weather phenomenon  and serves as a tipping element due to the collision of the two branches of monsoon  (Arabian Sea and Bay of Bengal)

 

Why is it crucial?

The summer monsoon contributes around 80% of India’s annual rainfall

Despite services and industry contributing the most to the gross domestic product, agriculture still employs almost half of the working population, says 2011 Census

The long-range accurate prediction of the monsoon is a matter of life or death both in terms of employment and farm output.  Even the stock markets reacted positively when the IMD predicted a higher than normal monsoon this year
