RISGeographical Dependence Observed in Blocking High Influence on the Stratospheric Variability through Enhancement and Suppression of Upward Planetary-Wave Propagation
Publisher: American Meteorological Society
Abstract: revious studies have suggested the importance of blocking high (BH) development for the occurrence of stratospheric sudden warming (SSW), while there is a recent study that failed to identify their statistical linkage. ...
Observed Temperature Two-Day Wave and Its Relatives near the Stratopause
Publisher: American Meteorological Society
Abstract: The two-day wave is observed in the Upper Atmosphere Research Satellite Microwave Limb Sounder temperature data around 40?58 km. Between December 1991 and September 1994, the two-day wave temperature signature is most ...
A Numerical Simulation of the Two-Day Wave near the Stratopause
Publisher: American Meteorological Society
Abstract: The middle atmosphere version of the National Center for Atmospheric Research Community Climate Model 2 (MACCM2) mechanistic model is used to simulate several aspects of the observed two-day wave near the stratopause and ...
An Observational Study of the Final Breakdown of the Southern Hemisphere Stratospheric Vortex in 2002
Publisher: American Meteorological Society
Abstract: The 2002 Southern Hemisphere final warming occurred early, following an unusually active winter and the first recorded major warming in the Antarctic. The breakdown of the stratospheric polar vortex in October and November ...
The Relevance of the Location of Blocking Highs for Stratospheric Variability in a Changing Climate
Publisher: American Meteorological Society
Abstract: revious research shows that blocking highs (BHs) influence wintertime polar stratospheric variability through the modulation of the climatological planetary waves (PWs) depending on the BH location. BHs over the Euro-Atlantic ...
The Atlantic Multidecadal Variability Phase Dependence of Teleconnection between the North Atlantic Oscillation in February and the Tibetan Plateau in March

Polarized Response of East Asian Winter Temperature Extremes in the Era of Arctic Warming
Publisher: American Meteorological Society
Abstract: AbstractIt has been argued that fewer cold extremes will be expected to occur over most midlatitude areas, because of anthropogenic-induced global warming. However, East Asia repeatedly suffered from unexpected cold spells ...
