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

This study investigates the characteristic large scale flow patterns associated with fast, slow and looping tropical cyclone motion in the western Atlantic and the western North Pacific.

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.

The phenomenon of vacillation in a rotating annulus is studied as a possible analogue for the atmospheric index cycle.

The development of a mesoscale circulation by the thermal contrast between a fire burned area surrounded by untouched vegetation was simulated by the Regional Atmospheric Modeling System (RAMS) in order to show the circulation's ability to generate clouds and precipitation.
