What is a Jet Stream? Live Science

The strongest jet streams are the polar jets around the polar vortices, at 9–12 km (5.6–7.5 mi; 30,000–39,000 ft) above sea level, and the higher altitude and somewhat weaker subtropical jets at 10–16 km (6.2–9.9 mi; 33,000–52,000 ft). The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet. The northern hemisphere polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oce… 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.

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. WebJet streams occur in both the Northern and Southern Hemispheres. The actual appearance of jet streams result from the complex interaction between many variables - such as the …
