RISOcean–Atmosphere Coupling on Different Spatiotemporal Scales: A Mechanism for Intraseasonal Instabilities
Publisher: American Meteorological Society
Abstract: The possibility of interactions between oceanic and atmospheric oscillations with different temporal and spatial scales is examined with analytical solutions to idealized linear governing equations. With a reasonable choice ...
Impact of Northward-Propagating Intraseasonal Variability on the Onset of Indian Summer Monsoon
Publisher: American Meteorological Society
Abstract: he onset of the Indian summer monsoon (ISM) has a pronounced interannual variability, part of which originates from the large-scale circulation and its thermodynamic properties. While the northward-propagating intraseasonal ...
Internal Variability of Indian Ocean SST
Publisher: American Meteorological Society
Abstract: A 40-yr integration of an eddy-resolving numerical model of the tropical Indian Ocean is analyzed to quantify the interannual variability that is caused by the internal variability of ocean dynamics. It is found that along ...
Temperature Advection by Tropical Instability Waves
Publisher: American Meteorological Society
Abstract: A numerical model of the tropical Pacific Ocean is used to investigate the processes that cause the horizontal temperature advection of tropical instability waves (TIWs). It is found that their temperature advection cannot ...
The Role of Negative Buoyancy in Surface-Based Convection and Its Representation in Cumulus Parameterization Schemes
Publisher: American Meteorological Society
Abstract: everal warm season, late-afternoon precipitation events are simulated over the Chesapeake Bay watershed using the Weather Research and Forecasting (WRF) model at three different resolutions. The onset and peak of surface-based ...
Kinetic Energy Budget for the Madden–Julian Oscillation in a Multiscale Framework
Publisher: American Meteorological Society
Abstract: kinetic energy budget for the Madden?Julian oscillation (MJO) is established in a three-scale framework. The three scales are the zonal mean, the MJO scale with wavenumbers 1?4, and the small scale with wavenumbers larger ...
Seasonal Influence of Indonesian Throughflow in the Southwestern Indian Ocean
Publisher: American Meteorological Society
Abstract: The influence of the Indonesian Throughflow (ITF) on the dynamics and the thermodynamics in the southwestern Indian Ocean (SWIO) is studied by analyzing a forced ocean model simulation for the Indo-Pacific region. The warm ...
Dynamics of the Intraseasonal Oscillations in the Indian Ocean South Equatorial Current
Publisher: American Meteorological Society
Abstract: The spatial and temporal features of intraseasonal oscillations in the southwestern Indian Ocean are studied by analyzing model simulations for the Indo-Pacific region. The intraseasonal oscillations have periods of 40?80 ...
Why Are There Tropical Warm Pools?
Publisher: American Meteorological Society
Abstract: Tropical warm pools appear as the primary mode in the distribution of tropical sea surface temperature (SST). Most previous studies have focused on the role of atmospheric processes in homogenizing temperatures in the warm ...
Interannual to Interdecadal Variabilities of the Indonesian Throughflow Source Water Pathways in the Pacific Ocean
Publisher: American Meteorological Society
Abstract: ome of the possible interannual to interdecadal variabilities of the Indonesian Throughflow (ITF) source water pathways in the Pacific Ocean are identified from an ocean reanalysis product provided by the European Centre ...
