RISResponse of the Eastern Tropical Pacific to Meridional Migration of the ITCZ: The Generation of the Costa Rica Dome
Publisher: American Meteorological Society
Abstract: A regional ocean circulation model with fine horizontal resolution has been developed in order to obtain a coherent seasonal picture of the eastern tropical Pacific off Central America. The Costa Rice Dome with a cyclonic ...
Response of the Western Tropical Pacific to the Asian Winter Monsoon: The Generation of the Mindanao Dome
Publisher: American Meteorological Society
Abstract: We have investigated the evolution of the Mindanao Dome off the Philippine coast using the GFDL ocean model. It is found that the model's Mindanao Dome evolves in late fall due to local upwelling when a positive curl ...
Structure of SST and Surface Wind Variability during Indian Ocean Dipole Mode Events: COADS Observations
Publisher: American Meteorological Society
Abstract: A study of the detailed spatiotemporal characteristics of the Indian Ocean dipole (IOD) mode in SST and surface winds using available observations from 1958 till 1997 is reported. The analysis is used to address several ...
Decadal Climate Variability in the North Pacific during the Recent Decades
Publisher: American Meteorological Society
Abstract: Decadal wintertime variability in the North Pacific climate system observed over the last few decades is documented. The decadal sea surface temperature (SST) variability is found to be concentrated around two major oceanic ...
Remote Effects of El Niño and Modoki Events on the Austral Summer Precipitation of Southern Africa
Publisher: American Meteorological Society
Abstract: emote effects modulating the austral summer precipitation over southern Africa during El Niño/El Niño Modoki events are investigated by analyzing the observed events during December?February of the years from 1982/83 to ...
Role of Rossby Waves in the Remote Effects of the North Indian Ocean Tropical Disturbances
Publisher: American Meteorological Society
Abstract: emote effects due to the tropical disturbances in the north Indian Ocean are investigated by analyzing long-lasting (≥5 days) tropical disturbances, which reached at least the strength of tropical storms. The present ...
Unstable Air-Sea Interactions in the Tropics
Publisher: American Meteorological Society
Abstract: During El Niño Southern Oscillation events modest anomalies amplify spatially and temporally until the entire tropical Pacific Ocean and the global atmospheric circulation are affected. Unstable interactions between the ...
Simulation of Interannual SST Variability in the Tropical Indian Ocean
Publisher: American Meteorological Society
Abstract: A 2.5-layer thermodynamic ocean model is used to investigate interannual variability in sea surface temperature (SST) of the tropical Indian Ocean. Simulated SST agrees well with the data. Model and observed SSTs exhibit ...
Tropical Indian Ocean Variability in the IPCC Twentieth-Century Climate Simulations
Publisher: American Meteorological Society
Abstract: The twentieth-century simulations using by 17 coupled ocean?atmosphere general circulation models (CGCMs) submitted to the Intergovernmental Panel on Climate Change?s Fourth Assessment Report (IPCC AR4) are evaluated for ...
Variational Interpolation of Circulation with Nonlinear, Advective Smoothing
Publisher: American Meteorological Society
Abstract: A modified variational algorithm, previously proposed in meteorology, is presented for the interpolation of oceanic hydrographic and velocity data. The technique is anisotropic and involves a variational approach that ...
