Extended rainy season likely: Experts

Weather experts have predicted that the current rainy season may get extended up to early December in Marathwada and other parts of the state. The intensity of rainfall during such extended period, however, may be not as vigorous as witnessed during past instances of protracted rainy season.

Shriniwas Aundhkar, director of city based APJ Abdul Kalam Astro Space and Science Centre, on Tuesday said that the average Equatorial Pacific Sea Surface Temperature may go down in near future producing La Niña conditions. “La Niña is a complex weather system that occurs every few years and causes extended rainfall in parts of the country. As per early forecast, the weather systems concerned may evolve in such a manner that Marathwada and other parts of the state witness rainfall beyond the stipulated period,” he said.

The Indian Ocean Dipole (IOD), the difference in sea surface temperature between a western pole in the Arabian Sea and an eastern pole in the eastern Indian Ocean, gradually becoming negative may reduce the amount of showers during the possible extended period of the rainy season, Aundhkar said.
Echoing the possibility of extended rainy season, physicist and meteorologist Prof Kirankumar Johare said the current cloud conditions also give a hint that the rainy season was here to stay for a longer period that usual. “Going by the current weather systems, the monsoon has now just settled over Marathwada and other parts. We can observe Nimbus clouds at present which imply that extended rainy season is likely,” he said.

Marathwada observes rainy season from June to September during which the region gets average 679 mm rainfall. The region, so far, received 94% of total expected showers, shows official data.
