Extreme events will intensify and grow to be more frequent if present projections are taken into account, stated India Meteorological Department Director-General Dr. Mrutyunjay Mohapatra. Speaking to The Indian Express, He attributed the rise in international temperatures for the enhanced frequency of such events.
Dr. Mohapatra stated international temperatures had risen about 1.2 degrees Celsius from one hundred years ago. The corresponding rise in India has been about .6 degrees Celsius, with the peninsular portion experiencing a reduced transform compared to the country’s eastern, central, and northern components.
The Met division chief stated throughout his interview with The Indian Express that the troposphere was also heating up, alongside the surface temperature, top to larger capacity for water holding. According to research, a 1-degree Celsius rise in temperature corresponds to A 7-per cent larger moisture-holding capacity. Dr. Mohaptara stated rainfall will go up if the atmosphere’s water-holding capacity goes up.
According to the climate bureau chief, the probability of heavy rainfall has gone up. Studies also pointed to an enhanced frequency of heavy rainfall events — the cumulative rainfall more than a 24-hour period getting larger than 15 cm. Such events are on the rise in international tropical belts, like India exactly where the trend is evident in Gujarat, Maharashtra, West Bengal, and Odisha.
Dr. Mohapatra stated the quantity of light or moderate rainfall on an typical was decreasing, although events of intense rainfall had been growing. However, total monsoon rainfall has remained largely unchanged, which means that it rains heavily when it rains or not at all when it does not.
He pointed to the country’s central belt exactly where the trend is more pronounced. The IMD has observed declining rainfall more than Jharkhand and Kerala and adjoining places. However, rainfall activity has seen a rise in western Uttar Pradesh, West Bengal, and components of Karnataka.
While heat waves have gone up in central and northern India, coldwave circumstances are probably to decline due to larger temperatures. Lightning strikes have also seen an enhance, Dr. Mohapatra stated, as have thunderstorms due to larger atmospheric moisture content.
The climate specialist added the intensity of Bay of Bengal cyclones has not seen any important transform, but Arabian Sea cyclones have displayed growing intensity.
