Web28. feb 2024. · To see how, lets look to the jet stream. The jet stream is a river of air that circles the globe. It also carries storms from west to east around the globe. The polar jet stream separates the frigid polar air from the more temperate mid-latitude air. In the Northern Hemisphere summer, the air is warmer because the Earth is tilted toward the … WebThe amplified warming of the Arctic is one of several factors influencing atmospheric dynamics. In this work, we consider a series of numerical experiments to identify the role of Arctic sea ice reduction in affecting climate trends in the Northern Hemisphere. With this aim in mind, we use two independent mechanisms of ice reduction. The first is … edna zestiria
