Pune: Three Latest Research from Indian Institute of Technology Bhubaneswar, Indian Institute of Science of Education and Research Pune, Indian Institute of Technology Kharagpur, and the Ministry of Earth Science Indian National Center for marine information services has linked Covid-19 locking last year in March to an increase in abnormal At surface temperatures from both water bodies.
The study of Iit Bhubaneswar and Iiser Pune, explored the impact of locking, said the decline in aerosol pollution over Bay Bay last year caused sea level (SST) to heat up 0.3 degrees Celsius and up to 1.5 degrees Celsius in a certain time of the bag.
V VINOJ, researching researchers at IIT Bhubaneswar, told TII, “Strict locking measures last year reduced pollution which caused 30% heating in Bengal Bay.
The ocean has long memory and heating events can have implications for regional weather, including increasing events Extreme rainfall.
“When aerosols spread solar radiation, they have cooling effects because they reflect some sun radiation back into space.
“With this aerosol reduction during locking because there are fewer industrial and transportation activities, more solar radiation can reach sea level, causing warming,” Vino said.
“The existing high summer SST, climate change increases the ocean heat content and induced decline in aerosols and clouds, can be the perfect ingredients for any cyclone activity intensification.
We are still studying this aspect and may come with more findings Conclusive immediately, “Vino said.
The cyclone is far more likely to collect intensity above warmer waters.
Heating Arabic Sea and Bay Bengal are very connected to the recent intense cyclone and extreme rainfall events in India, scientists and inter-governmental panels regarding climate change have said.
IIT Bhubaneswar also studied the locking effect at Amphan Typhoon drawn through West Bengal in May 2020.
Heating sea level temperatures in the locking period in both Arab Sea and Bay Bay was also studied by IIT Kharagpur and Incois.
Kuttippachanan Kuttippurh, scientists from the center of the ocean, river, land atmosphere and science of land in Iit Kharagpur, said the main productivity of the Indian Ocean declined during the locking period due to increased sea level in the Arab Sea and Bay Bay.
The increase in SST also affects chlorophyll blooms and primary productivity of the sea.
The main author of this study, Sunana N, said the primary productivity was very important in the dynamics of web food, including sea fisheries.
“The decline in productivity in the ocean can have a major impact on marine life and those who depend on it and affect the ocean ecology,” he said.
Kunal Chakrabort, senior scientist from Incois, said that less aerosol pollution can reduce the deflection of solar radiation which can then increase the temperature of the Hindown Ocean during the locking period.
This study analyzed the main productivity of the Indian Ocean for the period 2003-2019, and for 2020 to test the effect of Covid-19 locking.
The researchers divided 2020 to pre-lockdown (1 January – March 24), Lockdown (March 25 to June 7) and post-lockdown (8 -30) time frames.
Both of these studies were published in international journal Frontiers in Marine Sciences.
