RIS1997: The El Niño of the Century and the Response of the Indian Summer Monsoon
Publisher: American Meteorological Society
Abstract: The year 1997 was characterized by the rapid development of an El Niño whose strength exceeded any previously observed this century. The basic understanding of the influence of El Niño on the Asian summer monsoon suggested ...
The Diurnal Cycle of Convection and Atmospheric Tides in an Aquaplanet GCM
Publisher: American Meteorological Society
Abstract: The diurnal cycle of tropical convection and its relationship to the atmospheric tides is investigated using an aquaplanet GCM. The diurnal and semidiurnal harmonics of precipitation are both found to contribute significantly ...
The Mean Evolution and Variability of the Asian Summer Monsoon: Comparison of ECMWF and NCEP–NCAR Reanalyses
Publisher: American Meteorological Society
Abstract: The behavior of the Asian summer monsoon is documented and compared using the European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis (ERA) and the National Centers for Environmental Prediction?National Center ...
The Relationship between Convection and Sea Surface Temperature on Intraseasonal Timescales
Publisher: American Meteorological Society
Abstract: The relationship between tropical convection, surface fluxes, and sea surface temperature (SST) on intraseasonal timescales has been examined as part of an investigation of the possibility that the intraseasonal oscillation ...
Simulation of Crop Yields Using ERA-40: Limits to Skill and Nonstationarity in Weather–Yield Relationships
Publisher: American Meteorological Society
Abstract: Reanalysis data provide an excellent test bed for impacts prediction systems, because they represent an upper limit on the skill of climate models. Indian groundnut (Arachis hypogaea L.) yields have been simulated using ...
Modeling Diurnal and Intraseasonal Variability of the Ocean Mixed Layer
Publisher: American Meteorological Society
Abstract: The intraseasonal variability of SST associated with the passage of the Madden?Julian oscillation (MJO) is well documented; yet coupled model integrations generally underpredict the magnitude of this SST variability. ...
Toward a Combined Seasonal Weather and Crop Productivity Forecasting System: Determination of the Working Spatial Scale
Publisher: American Meteorological Society
Abstract: A methodology is presented for the development of a combined seasonal weather and crop productivity forecasting system. The first stage of the methodology is the determination of the spatial scale(s) on which the system ...
Representing El Niño in Coupled Ocean–Atmosphere GCMs: The Dominant Role of the Atmospheric Component
Publisher: American Meteorological Society
Abstract: A systematic modular approach to investigate the respective roles of the ocean and atmosphere in setting El Niño characteristics in coupled general circulation models is presented. Several state-of-the-art coupled models ...
Toward a New Generation of World Climate Research and Computing Facilities
Publisher: American Meteorological Society
Abstract: ding threat of global climate change and its regional manifestations is among the most important and urgent problems facing humanity. Society needs accurate and reliable estimates of changes in the probability of regional ...
