By Mir Afroz Zaman, POBNEWS24, Dhaka Aug 31, 2022 : Another global climate anomaly is looming. The ‘La Nina’ prevailing over the Pacific Ocean since September 2020 is entering its third year. La Niña is a climate pattern characterized by the influence of cold ocean currents.
According to India Meteorological Department data, since 1950 La Nina effects have lasted for more than two years only six times.
Colder-than-normal sea surface temperatures in the central and equatorial Pacific are typically called La Nina. Experts say La Nina is conducive to summer rainfall in the Indian region. But the dangerous aspect of La Nina is that it is also responsible for frequent cyclones in the Atlantic Ocean and Bay of Bengal.
India has received 740.3 millimeters of rain this year till August 30; Which is 7 percent more than normal. Of India’s 36 states/UTs, 30 received normal or excess rainfall.
The opposite of La Nina is El Nino. It shows the effect of warm ocean currents.
In mid-August, meteorologists from Australia’s Bureau of Meteorology (BOM), US National Oceanic and Atmospheric Administration (NOAA) and India’s Monsoon Mission Climate Forecast System (MMCFS) confirmed that La Niña would last until the end of 2022.
In April this year, these agencies had predicted that the La Niña situation would end by August.
