Abstract: The impact of anomalous tropical forcing on the anomalous tropical and extratropical circulation is examined by comparing the response of a global steady state linear primitive equation model with observations for nine ...

Abstract: Two large?scale precipitation datasets, one produced by the Global Precipitation Climatology Project (GPCP) and the other by the Climate Prediction Center of the National Weather Service, and called Climate Prediction ...

Abstract: For the uncoupled atmospheric general circulation model (AGCM) simulations, the quantification of errors due to the lack of coupled ocean?atmospheric evolution on the characteristics of the atmospheric interannual variability ...

Abstract: Three-day accumulations of precipitation for 2.5° long ? 2.0° lat areas along the west coast of the United States are used to rank precipitation events. Extreme precipitation events (those above the 90th percentile) occur ...

Abstract: Tropical intraseasonal convective anomalies (TICA) have a central role in subseasonal changes in the coupled ocean?atmosphere system, but the climatology of TICA events has not been properly documented. This study exploits ...

Abstract: Tropical intraseasonal convective anomalies (TICAs) play a significant role in the coupled ocean?atmosphere system and the Madden?Julian oscillation (MJO) is the primary mode of this variability. This study describes ...

Abstract: Systematic forecast errors associated with active episodes of the tropical Madden?Julian oscillation (MJO) are examined using five winters of dynamical extended range forecasts from the National Centers for Environmental ...

Abstract: The impact of initial conditions on summer precipitation over North America for July?September was examined by comparing long-term simulations of the Atmospheric Model Intercomparison Project (AMIP) runs with the ensemble ...

Abstract: No Abstract Available.

Abstract: The second phase of the North American Monsoon Experiment (NAME) Model Assessment Project (NAMAP2) was carried out to provide a coordinated set of simulations from global and regional models of the 2004 warm season across ...
