Abstract: An analysis of the radiative damping of slowly modulated sinusoidal wave disturbances is presented. It is shown that it is possible to incorporate scale-dependent effects in a manner no more difficult than that used in the ...

Abstract: The mesospheric radiative damping rates for temperature perturbations with vertical wavelengths less than 6 km are calculated, based on previous works of Spiegel and Fels. Effects due to the breakdown of local thermodynamic ...

Abstract: Analytic functions which approximate six commonly used standard temperature profiles (the AFGL set, and the 1976 U.S. Standard) are described. These provide a uniform way of rounding off the sharp corners of the original ...

Abstract: We describe a semianalytical method for calculating solar tides in an atmosphere whose zonal mean velocity need not be close to solid-body rotation, but which varies slowly in the vertical direction. The scheme is closely ...

Abstract: The ?trapeze instability? of Orlanski is investigated in the absence of a reflecting lid above the fluctuating layer. An expansion of the exact solution as a power series in a parameter representing the ratio of the ...

Abstract: The scattering of two-dimensional, hydrostatic, Boussinesq, internal gravity waves by orographic features is considered, with special attention paid to energy and momentum fluxes. A general integral equation for the ...

Abstract: Because of the requirement of geostrophic balance, mechanical inertia can affect the thermal response of the atmosphere to transient heating. We examine some very simple linear models of this ?flywheel effect,? and discuss ...

Abstract: A new scheme for the efficient calculation of longwave radiative heating rates is proposed. Its speed and accuracy make it attractive for use in large atmospheric circulation models. The approximation suggested iswhere q ...
