While it has been an irregular, at times unusuallywarm winterso far for parts of the United States, the nation can start bracing for some cold temperatures and snow later this month. AccuWeather reports that a mid-January shift in thepolar vortexwill send waves of cold air southward, upping ...

In summer, the reduced pole-to-equator temperature gradient (as compared to winter) leads to weaker and more-narrow upper-level westerlies, and the stratospheric polar vortex is absent all together (Fig.2). The role of the stratosphere in influencing boreal summer weather is therefore considered ...
January is a time when many of us pause to reflect on the previous year and look ahead to the one before us. It is also a time of year when we feel balanced between late fall work and the promise of a new spring. Here are some of our highlights from 2023. We share…Continue readi...
The first Q16DW may make a little contribution to polar vortex intensification due to small EP flux divergence. However, the Q16DW in the SSW has a strong negative divergence almost in the whole polar stratosphere, implying an important role in the stratospheric zonal wind reduction in the SSW...
被引量: 0发表: 2023年 Stretched polar vortex increases mid-latitude climate variability during the Last Glacial Maximum The Arctic stratospheric polar vortex (PV) is a key driver of winter weather, and has been found playing role in winter climate variability and its predict... Zhang, Yurui,Re...
第33题B 细节理解题。根据第三段的"Arctic blasts(北极寒流),like those in January 2019, happen when the polar vortex becomes unstable,allowing frigid air to spill south."可知,像2019年1月份波士顿的天气一样,极地涡旋变得不稳定,导致冷空气...
