What Causes Jet … WebJet streams are formed where cold air from the poles meets warm air from the tropics. The temperature difference creates a pressure gradient, which in turn creates high-speed winds. These winds move in a wavy pattern known as Rossby waves, which can be amplified or weakened by various factors, such as the location of high and low-pressure systems. 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 traditionally … how to say lydia in japanese
