Abstract: The behavior of large-scale patterns of sea level pressure is documented using a simple composite analysis over the period 1951?85. One interpretation of the maps shows that anomalies of a given sign appear sequentially ...

Abstract: Ensemble forecasts of global climate conditions during the seven largest Pacific warm/cold events of the last 23 years have been made with a new two-tiered climate forecast technique. The internal model variability (IMV) ...

Abstract: The relative roles of heat and freshwater fluxes in forcing the tropical Pacific on interannual timescales are investigated using sophisticated atmospheric and oceanic general circulation models. Interannual density flux ...

Abstract: Seasonal climate anomalies over North America exhibit rather large variability between years characterized by the same ENSO phase. This lack of consistency reduces potential statistically based ENSO-related climate ...

Abstract: This study summarizes results of an analysis of the TOGA drifting buoy observations in the Southern Hemisphere. The data were first quality controlled for gross errors and then screened against climatology and products ...

Abstract: The signature of ENSO in the wintertime frequencies of heavy precipitation and temperature extremes is derived from both observations and atmospheric general circulation model output for the contiguous United States. ENSO ...

Abstract: Two different sea-level pressure datasets for the strip between 20° and 40°S are intercompared. At large space-time scales the sets are virtually identical. However, for studies of short-term, regional changes caution must ...

Abstract: When a numerical model's representation of a physical field is to be compared with a corresponding real observed field, it is usually the case that the numbers of realizations of model and observed field are relatively ...
