A Japanese forecaster has said that the unique combination of a negative Indian Ocean Dipole (IOD) and an El Nino in the Pacific may lead to major shortfall of rain for India during this monsoon.

Updated forecasts by the Tokyo-based Regional Institute for Global Change show that the poor rain trend of June is likely to extend into July, August and September.

Combined Period

The deficits apply even if one were to take combined quarterly performance of the monsoon for June-July-August and July-August-September.

The developing El Nino is expected to peak during the next two months and would continue at least through the winter.

The Tokyo Centre, which is under the Japanese national forecaster Jamstec, said that the probability of a negative IOD is ‘very high’ in the tropical Indian Ocean during the summer and the autumn.

IOD, with a negative and positive phase, mimics El Nino-La Nina conditions in the Indian Ocean. A positive IOD has been found to support the cause of a concurrent Indian monsoon.

Autumn Warmer

Most part of Europe, Africa, West Asia, Russia, India, and Southeast Asia will experience a warmer-than-normal summer owing to the development of El Nino. But the Far East will experience a cooler summer.

The warm summer conditions will continue into the autumn for most parts of Europe, Africa, West Asia, Russia, India, Southeast Asia, and Mexico.

It will be cooler in most parts of China, eastern-central part of the US, southeast Canada, Korea and Japan.

In the Southern Hemisphere, most parts of Australia and South Africa will experience a colder winter. But most parts of Africa and South America will likely have a warmer winter.
