RISClimate Regime Variability for Past and Present Time Slices Simulated by the Fast Ocean Atmosphere Model
Publisher: American Meteorological Society
Abstract: This paper presents an analysis of Northern Hemisphere climate regime variability for three different time slices, simulated by the Fast Ocean Atmosphere Model (FOAM). The three time slices are composed of present-day ...
Toward Understanding the Dynamical Origin of Atmospheric Regime Behavior in a Baroclinic Model
Publisher: American Meteorological Society
Abstract: Dynamical mechanisms of atmospheric regime behavior are investigated in the context of a quasigeostrophic three-level T21 model of the wintertime atmospheric circulation over the Northern Hemisphere. The model, driven by ...
Circulation Regimes due to Attractor Merging in Atmospheric Models
Publisher: American Meteorological Society
Abstract: From a dynamical systems theory perspective, the mechanisms of atmospheric regime behavior in a barotropic model, a pseudobarotropic model, and a baroclinic three-level model, where all of them show quite realistic regimes, ...
Winter Weather Patterns over Northern Eurasia and Arctic Sea Ice Loss
Publisher: American Meteorological Society
Abstract: sing NCEP?NCAR reanalysis and Japanese 25-yr Reanalysis (JRA-25) winter daily (1 December?28 February) data for the period 1979?2012, this paper reveals the leading pattern of winter daily 850-hPa wind variability over ...
The Arctic Cloud Puzzle: Using ACLOUD/PASCAL Multiplatform Observations to Unravel the Role of Clouds and Aerosol Particles in Arctic Amplification
Publisher: American Meteorological Society
Abstract: AbstractClouds play an important role in Arctic amplification. This term represents the recently observed enhanced warming of the Arctic relative to the global increase of near-surface air temperature. However, there are ...
