Extratropical eddy distributions in four months typical of the four seasons are treated in terms of temporal mean and temporal r.m.s. values of the geostrophic relative vorticity.
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.
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.
Denver air pollution is removed in part by what is called the friction-stovepipe effect, a net indraft of air into the city which rises there and then moves outward again; in part by ventilation from winds blowing across town horizontally; and to a smaller extent by vertical turbulence in the middle of the day.
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.
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.
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.
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.
An estimation of the relative importance of various factors to the rainfall in West Central Africa has been attempted. The factors considered were tropical waves, monsoon depressions, the position of the intertropical discontinuity (ITD) and the tropical easterly jet stream (TEJ) of summer.
