Abstract: An analysis is made of low-latitude, large-scale, zonally asymmetric motions that result from the influence of stationary extratropical disturbances. A linear, two-layer, primitive-equation model in spherical coordinates ...

Abstract: A simple model is used to study the mechanisms which control the local and remote (teleconnection) response of the atmosphere to the thermal forcing resulting from sea surface temperature (SST) anomalies located at various ...

Abstract: Two apparently contradictory situations are provided by observations of the atmospheric response to sea surface temperature anomalies. These are: (i) The extratropical regions of the winter hemisphere appear to possess ...

Abstract: Observations indicate that monsoon systems are characterized by orderly large-scale and low-frequency variations. With a time scale of two weeks and sometimes longer, regions of ascending motion are observed to form to the ...

Abstract: The response of the tropical atmosphere to steady forcing for all four seasons is computed using a simple two-layer linear primitive-equation model allowing an arbitrary basic flow with two-dimensional shear. The character ...

Abstract: Linear shallow water equations are employed to study the effects of basic zonal flows on equatorially trapped waves. Analytical solutions are obtained for constant basic zonal flows. It is shown that changes in the wave ...

Abstract: Atmospheric equatorial perturbations generated by extratropical transient forcing are simulated numerically in a linear model. Impacts of mean zonal wind on such lateral forcing processes are emphasized. The extratropical ...

Abstract: Most attempts at predicting south Asian monsoon variability have concentrated on seasonally averaged rainfall over the Indian subcontinent some months in advance using regional and remote boundary effects as predictors. ...

Abstract: Despite significant progress in the Tropical Ocean?Global Atmosphere (TOGA) program, a number of major hurdles remain before the primary objective, prediction of the variability of the coupled ocean?atmosphere system on ...
