RISThe Curious Case of Indian Ocean Warming
Publisher: American Meteorological Society
Abstract: ecent studies have pointed out an increased warming over the Indian Ocean warm pool (the central-eastern Indian Ocean characterized by sea surface temperatures greater than 28.0°C) during the past half-century, although ...
Extended ENSO Predictions Using a Fully Coupled Ocean–Atmosphere Model
Publisher: American Meteorological Society
Abstract: Using a fully coupled global ocean?atmosphere general circulation model assimilating only sea surface temperature, the authors found for the first time that several El Niño?Southern Oscillation (ENSO) events over the past ...
Decadal Modulations of the Indian Ocean Dipole in the SINTEX-F1 Coupled GCM
Publisher: American Meteorological Society
Abstract: The decadal variation in the tropical Indian Ocean is investigated using outputs from a 200-yr integration of the Scale Interaction Experiment-Frontier Research Center for Global Change (SINTEX-F1) ocean?atmosphere coupled ...
Experimental Forecasts of the Indian Ocean Dipole Using a Coupled OAGCM
Publisher: American Meteorological Society
Abstract: The Indian Ocean Dipole (IOD) has profound socioeconomic impacts on not only the countries surrounding the Indian Ocean but also various parts of the world. A forecast system is developed based on a relatively high-resolution ...
Seasonally Stratified Analysis of Simulated ENSO Thermodynamics
Publisher: American Meteorological Society
Abstract: Using outputs from the SINTEX-F1 coupled GCM, the thermodynamics of ENSO events and its relation with the seasonal cycle are investigated. Simulated El Niño events are first classified into four groups depending on during ...
The Role of the Western Arabian Sea Upwelling in Indian Monsoon Rainfall Variability
Publisher: American Meteorological Society
Abstract: The Indian summer monsoon rainfall has complex, regionally heterogeneous, interannual variations with huge socioeconomic impacts, but the underlying mechanisms remain uncertain. The upwelling along the Somalia and Oman ...
Control and Stabilization of the Gulf Stream by Oceanic Current Interaction with the Atmosphere
Publisher: American Meteorological Society
Abstract: he Gulf Stream (GS) is known to have a strong influence on climate, for example, by transporting heat from the tropics to higher latitudes. Although the GS transport intensity presents a clear interannual variability, ...
Subtropical Dipole Modes Simulated in a Coupled General Circulation Model
Publisher: American Meteorological Society
Abstract: he growth and decay mechanisms of subtropical dipole modes in the southern Indian and South Atlantic Oceans and their impacts on southern African rainfall are investigated using results from a coupled general circulation ...
Role of Tropical SST Variability on the Formation of Subtropical Dipoles
Publisher: American Meteorological Society
Abstract: nterannual variations of sea surface temperature (SST) in the midlatitudes of the Southern Hemisphere play an important role in the rainfall variability over the surrounding countries by modulating synoptic-scale atmospheric ...
Reducing Climatology Bias in an Ocean–Atmosphere CGCM with Improved Coupling Physics
Publisher: American Meteorological Society
Abstract: The cold tongue in the tropical Pacific extends too far west in most current ocean?atmosphere coupled GCMs (CGCMs). This bias also exists in the relatively high-resolution SINTEX-F CGCM despite its remarkable performance ...
