When the rains hit a hattrick

T. Balaji popularly known as the Telangana Weatherman tweeted that this is the third consecutive year that the average cumulative rainfall during the southwest monsoon has crossed 1,000 mm. "Telangana SWM Average rainfall crosses 1000 mm by today, thus we are having hatrick years of 1000mm+ average rains in Telangana during SWM (2020,21,22). This is the first time this has happened in the last 70years where we are having hatrick years of 1000mm+ rains (sic)," he tweeted.



According to the TSDPS data, the cumulative average rainfall in 2020 was 1,009.7 mm and in 2021, it was 1,078.3 mm. Balaji further said that with 20 days left for the southwest monsoon to end, there are chances that this year's rains will break the 2020 record.

"The excess rainfall this year, similar to the last two years, is due to the La Nina effect and MJO conditions prevailing in our basin area. La Nina refers to temperature variations (cooler than average ocean water) in the Pacific Ocean whereas MJO is a periodic movement of waves around the tropic zone. La Nina is slowly changing (persisting for the last 2 years) whereas MJO is fast changing and occurs every 15-30 days," explained Balaji.

Speaking about the rainfall conditions in the coming days, he said, "There is a low-pressure system prevailing around the Chattisgarh-Vidarbha area. It is gradually moving further into Madhya Pradesh. The rains in Hyderabad will reduce from today (11 September) and in other parts of the state especially Northern Telangana where incessant rains are happening, the rains will reduce from tomorrow (12 September)."
