RISAGCM Precipitation Biases in the Tropical Atlantic
Publisher: American Meteorological Society
Abstract: Many general circulation models (GCMs) share similar biases in the representation of the intertropical convergence zone (ITCZ) in the Atlantic, even when they are forced with the time series of the observed sea surface ...
HITS: Hurricane Intensity and Track Simulator with North Atlantic Ocean Applications for Risk Assessment
Publisher: American Meteorological Society
Abstract: nonparametric stochastic model is developed and tested for the simulation of tropical cyclone tracks. Tropical cyclone tracks demonstrate continuity and memory over many time and space steps. Clusters of tracks can be ...
The Recent Increase in North Atlantic Wave Heights
Publisher: American Meteorological Society
Abstract: The nature and causes of the recent increase in North Atlantic wave heights are explored by combining a numerical hindcast with a statistical analysis. The numerical hindcast incorporates a 10-yr history (1980?89) of North ...
Atmospheric GCM Response to Extratropical SST Anomalies: Synthesis and Evaluation
Publisher: American Meteorological Society
Abstract: The advances in our understanding of extratropical atmosphere?ocean interaction over the past decade and a half are examined, focusing on the atmospheric response to sea surface temperature anomalies. The main goal of the ...
Cross–Time Scale Interactions and Rainfall Extreme Events in Southeastern South America for the Austral Summer. Part I: Potential Predictors
Publisher: American Meteorological Society
Abstract: he physical mechanisms and predictability associated with extreme daily rainfall in southeastern South America (SESA) are investigated for the December?February season in a two-part study. Through a k-mean analysis, this ...
Multiscale Variability in North American Summer Maximum Temperatures and Modulations from the North Atlantic Simulated by an AGCM
Publisher: American Meteorological Society
Abstract: AbstractSix recurrent thermal regimes are identified over continental North America from June to September through a k-means clustering applied to daily maximum temperature simulated by ECHAM5 forced by historical SSTs for ...
Atlantic Climate Variability and Predictability: A CLIVAR Perspective
Publisher: American Meteorological Society
Abstract: Three interrelated climate phenomena are at the center of the Climate Variability and Predictability (CLIVAR) Atlantic research: tropical Atlantic variability (TAV), the North Atlantic Oscillation (NAO), and the Atlantic ...
