Arctic Amplification Phenomenon

Recently, some studies were revealed on Arctic Amplification, that instructed that the region is fast and ever-changing and the simplest of climate models might not be ready to capture the speed of changes and predict it accurately. The ice-albedo feedback, lapse rate feedback, vapor feedback (Change in vapor amplify or weaken temperature range), and ocean heat transport are the first causes.

Ocean ice and snow have high albedo (a measure of the reflectivity of the surface), implying that they’re capable of reflecting most of the radiation as critical water and land. Because the ocean ice melts, the ocean is capable of absorbing radiation, thereby driving the amplification.

The lapse rate or the speed at which the temperature drops with elevation decreases with warming. Studies show that the ice-albedo feedback and also the lapse rate feedback are accountable for four-hundred and 15 August 1945 of polar amplification severally.

In recent years, scientists have pondered over the impact the ever-changing Arctic will wear on the monsoons in the Indian subcontinent. The link between the 2 is growing in importance because of the intense weather events India faces, and also the serious reliance on rain for water and food security.

In 2021 a study (an attainable relation between Arctic Ocean ice and late season Indian summer Monsoon rain extremes) was revealed, that found that the reduced ocean ice within the Barents-Kara ocean region will cause extreme rain events within the latter 1/2 the monsoons — in September and October.

The changes within the region’s circulation because of decreasing ocean ice combined with the nice and cozy temperatures within the Arabian Sea contribute to increased wetness and drive extreme rain events. In line with the planet meteorological Organization’s report in 2021 (State of world Climate in 2021) water level on the Indian coast is rising quicker than the worldwide average rate.
