RISTropical-Extratropical Interaction Associated with the 30–60 Day Oscillation and Its Impact on Medium and Extended Range Prediction
Publisher: American Meteorological Society
Abstract: An observational and modeling study is made of tropical-extratropical interactions on time scales relevant to medium and extended range forecasting. First, an empirical orthogonal function (EOF) analysis is made of outgoing ...
Diagnosis of Extratropical Variability in Seasonal Integrations of the ECMWF Model
Publisher: American Meteorological Society
Abstract: Properties of the general circulation simulated by the ECMWF model are discussed using a set of seasonal integrations at T63 resolution. For each season, over the period of 5 years, 1986?1990, three integrations initiated ...
Low-Frequency Variability of the Indian Monsoon–ENSO Relationship and the Tropical Atlantic: The “Weakening” of the 1980s and 1990s
Publisher: American Meteorological Society
Abstract: The Indian monsoon?El Niño?Southern Oscillation (ENSO) relationship, according to which a drier than normal monsoon season precedes peak El Niño conditions, weakened significantly during the last two decades of the twentieth ...
The European Centre for Medium-Range Weather Forecasts (ECMWF) Program on Extended-Range Prediction
Publisher: American Meteorological Society
Abstract: Results from a 3 1/2-yr experimental program of extended-range integrations of the European Centre for Medium-Range Weather Forecasts (ECMWF) numerical weather prediction model are summarized. The topics discussed include ...
