The Steepening of Hydrostatic Mountain Waves
Publisher: American Meteorological Society
Abstract: The nonlinear effects in the flow of a Boussinesq stratified fluid over two-dimensional sinusoidal topography are examined in this paper using second-order perturbation theory. The waves generated by finite-amplitude ...
Transient Dynamics of Airflow near a Local Heat Source
Publisher: American Meteorological Society
Abstract: The response of a stratified atmosphere to local heating is a common element in several problems in mesoscale dynamics. To investigate this response, a time-dependent linearized problem is solved analytically for an elevated, ...
Water Vapor Transport and the Production of Precipitation in the Eastern Fertile Crescent
Publisher: American Meteorological Society
Abstract: The study presented here attempts to quantify the significance of southerly water vapor fluxes on precipitation occurring in the eastern Fertile Crescent region. The water vapor fluxes were investigated at high temporal ...
Orographic Precipitation in the Tropics: Experiments in Dominica
Publisher: American Meteorological Society
Abstract: The ?natural laboratory? of mountainous Dominica (15°N) in the trade wind belt is used to study the physics of tropical orographic precipitation in its purest form, unforced by weather disturbances or by the diurnal cycle ...
Orographic Enhancement of Precipitation inside Hurricane Dean
Publisher: American Meteorological Society
Abstract: On 17 August 2007, the center of Hurricane Dean passed within 92 km of the mountainous island of Dominica in the West Indies. Despite its distance from the island and its category 1?2 state, Dean brought significant total ...
