Flooding rainfall may occur!
Post-Monsoon to be very active!
La-Nina returning with a “+ phenomena”?
Will the Indian monsoon-friendly phenomena return back? Some experts at the Tokyo-based Regional Institute for Global Change (RIGC) have forecasted that La-Nina will return from August.These were the same experts who said that the La-Nina of 2010 would be completely over in June, which proved true. Last year, La-Nina brought above normal monsoon to many parts of Indian Sub continent with worst flooding in decades in Pakistan.
They have also said that flooding rainfall may occur in most parts of Indian-Sub continent from August till October due to the return of La-Nina and emergence of positive Indian Ocean Dipole along with it
Similar forecast was issued by U.S experts few days back. Already the La-Nina is being blamed for heat waves in United States and worst drought in Africa. US says La-Nina will return in later this year. Question is, Will it affect the South-West Monsoon? If La-Nina occurs in September or October than most of its effect will be on North-East monsoon, which does not occur in Pakistan. So La-Nina must start in August for it to increase the intensity of South-West monsoon. But it is also worth mentioning that most weather models does not forecast any La-Nina or +IOD, they say that conditions are likely to be neutral till 2012. So will the Japanese be proved right?
