The research on climate change in polar regions, especially on the role of polar in the global climate system, has gain unprecedented level of interest. It has been the key scientific issue of the International Polar Year program (IPY, 2007–2008). In this paper, we dealt with the debate upon the breakup time of the stratospheric polar vortex in boreal spring. An observational study of the relation between stratospheric polar vortex breakup and the extra-tropical circulation was performed. The… 

The boreal spring stratospheric final warming and its interannual and interdecadal variability

Based on the daily NCEP/DOE reanalysis II data, dates of the boreal spring Stratospheric Final Warming (SFW) events during 1979–2010 are defined as the time when the zonal-mean zonal wind at the

Vertical Structure of the Arctic Spring Transition in the Middle Atmosphere

In the middle atmosphere, spring transition is the time period where the zonal circulation reverses from winter westerly to summer easterly which has a strong impact on the vertical wave propagation

Impacts of stratospheric polar vortex changes on wintertime precipitation over the northern hemisphere

The impacts of Arctic stratospheric polar vortex (SPV) on wintertime precipitation over the Northern Hemisphere are analyzed based on various datasets. Two groups of ensemble climate model

Projected changes of stratospheric final warmings in the Northern and Southern Hemispheres by CMIP5/6 models

Using the historical, moderate emission scenario (RCP45/SSP245), and high emission scenario (RCP85/SSP585) experiments provided by the Coupled Model Intercomparison Project Phases 5 and 6 (CMIP5/6),
