The characteristics of the equatorial symmetric instability that develops if the mean flow is horizontally sheared at the equator are investigated.

Two basic experiments are shown: the first is a perturbation in the geopotential field, and the second is a perturbation in the rotational part of the wind field.

Results of several cloud simulations under different environmental and initial conditions are presented. These illustrate the capability of the model in simulating the entire life-cycle of cumulus clouds subject to different forcing conditions.

The sensitivity of mesoscale features with respect to large scale tropical profiles of wind and temperature and to small scale parameterizations is investigated through a linear, spectral, non-hydrostatic model.

A dry, two-dimensional version of the Colorado State University Multi-Dimensional Cloud/Mesoscale Model was used to simulate the cross-valley dynamic and thermodynamic structure in deep mountain valleys during the morning transition period when the nocturnal inversion is destroyed.

VHF wind profiler data were used to study the vertical draft structure within 13 tropical Mesoscale Convective Systems (MCSs) near Darwin, Australia during the wet season of 1989-1990 and 1990-1991.

This paper discusses the observational evidence for and the probable causes of the large diurnal variability of the atmosphere over the Inter Tropical Convergence Zone (ITCZ) region of the tropical eastern Atlantic Ocean.

In this paper an analysis is performed on a "minor breakdown" of the stratospheric circulation which occurred during a period of general intensification of the polar vortex (15 November to 15 December 1958).
