RISImpacts of Assimilation of Satellite and Rawinsonde Observations on Southern Hemisphere Baroclinic Wave Activity in the NCEP–NCAR Reanalysis
Publisher: American Meteorological Society
Abstract: In this study, the impacts of the assimilation of satellite and rawinsonde observations on Southern Hemisphere (SH) baroclinic wave activity in the NCEP?NCAR reanalysis are examined by comparing analyses made with and ...
Dynamics of the Stationary Anomalies Associated with the Interannual Variability of the Midwinter Pacific Storm Track—The Roles of Tropical Heating and Remote Eddy Forcing
Publisher: American Meteorological Society
Abstract: The leading mode of interannual variability of the midwinter Pacific storm track is such that the storm track is weaker during the winters when the Pacific jet is strong, and stronger when the jet is weak. In this paper, ...
Is Pacific Storm-Track Activity Correlated with the Strength of Upstream Wave Seeding?
Publisher: American Meteorological Society
Abstract: n this paper, the relationship between upstream seeding over north Asia and downstream storm-track activity over the North Pacific in midwinter and spring/fall has been analyzed using 45 years of variance and feature-tracking ...
Modulation of the Convectively Coupled Kelvin Waves over South America and the Tropical Atlantic Ocean in Association with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: n this study, evidence of the strong modulation of the convectively coupled Kelvin wave (CCKW) activity by the Madden?Julian oscillation (MJO) is presented, with a particular focus over the South America and tropical ...
Comments on “The Source of the Midwinter Suppression in Storminess over the North Pacific”
Publisher: American Meteorological Society
Abstract: n a recent paper, Penny et al. employed feature tracking to investigate why there is a relative minimum in storminess during winter within the Pacific storm track. They concluded that reduced upstream seeding, especially ...
A Systematic Relationship between the Representations of Convectively Coupled Equatorial Wave Activity and the Madden–Julian Oscillation in Climate Model Simulations
Publisher: American Meteorological Society
Abstract: he relationship between a model?s performance in simulating the Madden?Julian oscillation (MJO) and convectively coupled equatorial wave (CCEW) activity during wintertime is examined by analyzing precipitation from 26 ...
Variations of Northern Hemisphere Storm Track and Extratropical Cyclone Activity Associated with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates the intraseasonal variations of the Northern Hemispheric storm track associated with the Madden?Julian oscillation (MJO) during the extended boreal winter (November?April) using 36 yr ...
Storm-Track Activity in IPCC AR4/CMIP3 Model Simulations
Publisher: American Meteorological Society
Abstract: he climatological storm-track activity simulated by 17 Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4)/phase 3 of the Coupled Model Intercomparison Project (CMIP3) models is compared to that ...
Statistical Relationship between Atmospheric Rivers and Extratropical Cyclones and Anticyclones
Publisher: American Meteorological Society
Abstract: Statistical relationships between atmospheric rivers (ARs) and extratropical cyclones and anticyclones are investigated on a global scale using objectively identified ARs, cyclones, and anticyclones during 1979–2014. ...
