Web1 de ago. de 2024 · Abstract The latitudinal position of the Northern Hemisphere jet stream (NHJ) modulates the occurrence and frequency of extreme weather events. Precipitation anomalies in particular are associated with NHJ variability; the resulting floods and droughts can have considerable societal and economic impacts. This study develops … Web21 de ago. de 2013 · Much of the current focus centers around the jet stream, which is a channel of fast-flowing air at high altitudes that helps steer weather systems from west to east across the Northern Hemisphere, and it is powered by the huge difference in air temperatures between the equator and the poles.

WebActually atmospheric scientists had theorized the existence of jet streams at least as early as 1937. The bomber pilots just confirmed it. Now many television weathercasts mention the positions of jet streams and their impact on daily weather events. Jet streams are relatively strong winds concentrated as narrow currents in the upper atmosphere.

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 … hac triathlon
