The repeat La Nina conditions in the east equatorial Pacific are growing, and would continue do so in the following months, according to Japanese researchers.
The La Nina may die out during the northern hemisphere summer of 2012, according to researchers at the Tokyo-based Regional Institute for Global Change (RIGC) attached with the Japan Agency for Marine-Earth Science and Technology.
EARLIEST FORECAST
RIGC was the earliest global model to come out with a forecast for La Nina as far back as late last year.
In regional forecasts for the next few months, the RIGC said the developing La Nina would bring cool to wet conditions over southern Africa, Australia, Brazil, and India.
It would also help bring down surface temperatures over many parts of the globe except northern Eurasia and eastern US.
Eastern China, Korea and western Japan are likely experience colder weather during this winter, the RIGC said.
Meanwhile, back home, India Meteorological Department (IMD) extended the outlook for a brewing low-pressure system in the Bay of Bengal to Tuesday.
‘LOW' BY TUESDAY
Isolated heavy rain or thundershowers have been forecast over the Andaman and Nicobar Islands on Monday and Tuesday.
Extended outlook valid until Friday said that the ‘low' over east-central Bay might intensify further.
A short-term outlook until valid Wednesday said that fairly widespread rain or thundershowers would also lash Tamil Nadu, Kerala, Lakshadweep, Karnataka, Konkan, Goa and south Madhya Maharashtra.
Isolated rain or thundershowers are expected over east and northeast India, Gujarat, and Andhra Pradesh. Rainfall activity will scale up over the Northeastern States from Wednesday.
This could likely indicate a north-northeasterly movement of a well-marked ‘low' from east-central Bay.
WIDESPREAD RAIN
Fairly widespread rainfall activity has been forecast over the Northeastern States, the west coast and extreme south peninsular India during the period until Wednesday.
Meanwhile, the 24 hours ending Sunday morning saw fairly widespread rainfall being recorded over interior Karnataka, Kerala, Tamil Nadu and the Andaman and Nicobar Islands.
It was scattered over Meghalaya, Konkan, Goa and Madhya Maharashtra and isolated over sub-Himalayan West Bengal, Sikkim, Arunachal Pradesh,
Assam, Orissa, Telangana, coastal Andhra Pradesh and coastal Karnataka, the IMD said.
