RISOnset of Circulation Anomalies during Stratospheric Vortex Weakening Events: The Role of Planetary-Scale Waves
Publisher: American Meteorological Society
Abstract: o highlight the details of stratosphere?troposphere dynamical coupling during the onset of strong polar vortex variability, this study identifies stratospheric vortex weakening (SVW) events by rapid deceleration of the ...
Wave Events: Climatology, Trends, and Relationship to Northern Hemisphere Winter Blocking and Weather Extremes
Publisher: American Meteorological Society
Abstract: AbstractDiagnostics of finite-amplitude local wave activity (LWA) are applied to the 500-hPa geopotential height field to diagnose persistent synoptic weather events of anomalously large wave activity in the Northern ...

Modulations of North American and European Weather Variability and Extremes by Interdecadal Variability of the Atmospheric Circulation over the North Atlantic Sector
Publisher: American Meteorological Society
Abstract: The dominant mode of wintertime interdecadal covariability between subseasonal surface air temperature (SAT) variability and midtropospheric circulation over the North Atlantic sector is identified through maximum covariance ...
The Role of Transient Eddies in North Pacific Blocking Formation and Its Seasonality
Publisher: American Meteorological Society
Abstract: The mechanism of North Pacific (NP) blocking formation is investigated by conducting a reanalysis-based budget analysis of the quasigeostrophic geopotential tendency equation. It is confirmed that the amplification of NP ...
