WebJan 28, 2024 · Therefore, NAO can be regarded as a useful precursor for determining the type of forthcoming SSW events. Most sudden stratospheric warming (SSW) events initiate with their centers being displaced from the pole. Some retain their displaced form until termination but some split into two vortices during their course. WebScientists have long recognized that, on average, air pollution in the lower atmosphere is worse in the Northern Hemisphere than in the Southern Hemisphere. That’s because nearly 90 percent of the global population, and a majority of urban and industrial pollution sources, are located north of the equator. A new study has found that the northern stratosphere is …
