1. Introduction Understanding the extratropical atmospheric response to thermal and mechanical forcing is central to a range of current problems in climate dynamics. Midlatitude atmosphere–ocean interaction is a function of the tropospheric response to variations in surface diabatic heating, stratosphere–troposphere coupling is a function of the tropospheric response to changes in the shear of the flow at the tropopause level and/or diabatic heating in the polar stratosphere, and the

advance our understanding of the convective generation of gravity waves. However, gravity waves are relatively small-scale phenomena with wavelengths smaller than a few hundred kilometers, and consequently, very high spatial resolution is needed in order for GCMs to represent them accurately. This means that it is often necessary to parameterize the effects of the gravity waves in GCMs by adding to the equations of the model a term to represent the drag force that would have resulted from the gravity

–aerosol–transport model driven by model simulated/assimilated atmospheric temperature, humidity, and cloud fields. The products include not only the optical thickness but also the single scattering albedo and asymmetry factor, all of which are important for computing the radiative effect of aerosols [or aerosol radiative forcing (ARF)]. The National Aeronautics and Space Administration (NASA) launched the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) satellite on 1 August 1997 to measure global ocean color and to

02 ), but have not addressed the mechanisms by which Kelvin waves might be initially excited. In this paper, we argue that a substantial fraction of convectively coupled Kelvin waves are excited through a distinct forcing from the extratropics. Extratropical forcing has also been suggested to play an important role in initiating lower-frequency MJO events ( Liebmann and Hartmann 1984 ; Hsu et al. 1990 ; Meehl et al. 1996 ; Lin et al. 2000 ; Straus and Lindzen 2000 ). Convectively coupled
