University of Hyderabad (UoH) researchers have discovered that days with anomalously greater temperatures are rising throughout summer season whereas the days with anomalously decrease temperatures are reducing throughout winter yearly.
The prevalence of anomalously greater temperatures for consecutive three days or extra is known as a heat wave occasion and it was discovered heat wave occasions are rising at the price of 0.6 occasions per decade whereas the cold wave occasions are reducing at the price of 0.4 occasions per decade.
The study led by Master of Science in Ocean and Atmospheric Sciences, 2020-2022 batch scholar Aninda Bhattacharya confirmed that heat waves have change into extra frequent in summer season in the latest decade whereas cold waves have much less so frequent in winter in India.
The scholar used each day most temperature and minimal temperature knowledge from 1970 to 2019 to analyze the pattern in the frequency of prevalence of days with anomalously excessive temperatures (known as heat waves) and days with anomalously low temperature (known as cold waves) over completely different climatic areas of India.
The authors additionally in contrast the current-generation laptop fashions used to predict future local weather with India Meteorological Department (IMD) observations. Heat waves are discovered to be extra frequent over the arid and semi-arid climatic area whereas cold waves are much less so frequent over the identical area.
Others who had been a part of the analysis workforce are: Abin Thomas and Vijay Kanawade from Centre of Earth, Ocean and Atmospheric Sciences, School of Physics, UoH; with different collaborators being IIT Madras’s Chandan Sarangi, World Resources Institute’s (WRI) P. S. Roy from and IMD’s Vijay Ok. Soni. The study has been printed in The Journal of Earth System Science (https://www.springer.com/journal/12040)., mentioned a press launch.
