Tropical Dust Cyclones on Mars
Introduction: Atmospheric dust plays an important role in regulating the climate of Mars and strongly influences the deposition of incoming solar energy and outgoing infrared radiation, thereby affecting atmospheric dynamics through heating. The lifting of dust from the surface is fundamentally a result of atmospheric circulations, and this provides an opportuntity for feedback between atmosphe...
متن کاملThe Extratropical Transition of Tropical Cyclones
The objective is to investigate the physical processes that occur as a tropical cyclone interacts with the environment such that intensity and structure changes occur. Specific interactions being studied are with baroclinic environments in the midlatitudes during extratropical transition. During extratropical transition, radical changes to the storm structure occur as vertical wind shear and in...
متن کاملThe Dynamics of Extratropical Oceanic Cyclones
A temperature structure appropriate for maritime areas is employed to find exact solutions to the non-linear quasi-geostrophic omega and vorticity equations, using a procedure similar to that used in a quasigeostrophic model by Sanders (1971). Results are qualitatively similar to those found in the latter model, and thus, are consistent with the traditional baroclinic stability theory. The prin...
متن کاملCyclones, tides, and the origin of a cross-equatorial dust storm on Mars
[1] We investigate the triggering mechanism of a crossequatorial dust storm observed by Mars Global Surveyor in 1999. This storm, which had a significant impact on global mean temperatures, was seen in visible and infrared data to commence with the transport of linear dust fronts from the northern high latitudes into the southern tropics. However, other similar transport events observed in nort...
