The Martian Zonal-Mean Circulation: Angular Momentum and Potential Vorticity Structure in GCM Simulations

Creator:: Barnes, Jeffrey R. and Haberle, Robert M.
Abstract:: Analysis of simulations performed with the NASA/Ames Mars GCM shows that under dusty conditions the Northern Hemisphere winter solstice circulation becomes characterized by a zonally averaged state in which the potential vorticity at upper levels is very small outside of high latitudes. The available observational data-in particular the 15-µm observations...

A simplified three-dimensional model for Martian climate studies

Creator:: Haberle, Robert M., Houben, Howard, Barnes, Jeffrey R., and Vong, Richard E.
Abstract:: We described a simplified physics approach to generating time-varying global wind and temperature fields suitable for conducting transport studies on Mars. The goal is to develop a computationally fast algorithm that will enable long-term simulations of the planet’s climate system. Thus we use a three-dimensional log-pressure global spectral model forced...

Low-level jets in the NASA Ames Mars general circulation model

Creator:: Joshi, M. M., Haberle, Robert M., Barnes, Jeffrey R., Murphy, J. R., and Schaeffer, J.
Abstract:: Previous simulations of the Martian atmosphere have shown how topography acts to confine the low-level Hadley cell flow into intense jets on the eastern flanks of Tharsis and Syrtis Major. We now conduct detailed studies of these jets using the NASA Ames Mars general circulation model (MGCM). The structure of...

Meteorological predictions for the Mars Pathfinder lander

Creator:: Haberle, Robert M., Barnes, Jeffrey R., Murphy, James R., Joshi, Manoj M., and Schaeffer, James
Abstract:: The NASA Ames Mars general circulation and boundary layer models are used as guides to forecast the meteorological environment of the Pathfinder lander site. Based on these models we predict that for a Viking-like atmospheric dust loading, significant vertical wave structure will be seen in the entry temperature profile above...

Mars atmospheric dynamics as simulated by the NASA Ames general circulation model, 3. Winter quasi-stationary eddies

Creator:: Barnes, Jeffrey R., Haberle, Robert M., Pollack, James B., Lee, Hilda, and Schaeffer, James
Abstract:: A set of simulations with the NASA Ames Mars general circulation model (GCM) has been analyzed to define the basic properties and dynamics of quasi-stationary eddy circulations in the winter hemisphere. These circulations, differing substantially from those in low latitudes and the summer hemisphere, extended from the surface to the...

Agonistic behavior in three species of Microtus (M. canicaudus, M. oregoni, and M. townsendii)

Creator:: Weil, James Wayne
Abstract:: Agonistic behavior among three species of Microtus live-trapped near Corvallis, Oregon was recorded in order to interpret habitat segregation by the species in areas of syrnpatry. The method used to measure agonistic interaction was similar to that of Colvin (1970). Agonistic behavior was recorded under red light in a neutral...

General circulation model simulations of the Mars Pathfinder atmospheric structure investigation/meteorology data

Creator:: Haberle, Robert M., Joshi, Manoj M., Murphy, James R., Barnes, Jeffrey R., Schofield, John T., Wilson, Greg, Lopez-Valverde, Miguel, Hollingsworth, Jeffrey L., Bridger, Alison F. C., and Schaeffer, James
Abstract:: The NASA Ames Mars General Circulation Model is used to interpret selected results from the Mars Pathfinder atmospheric structure instrument/meteorology (ASI/MET) experiment. The present version of the model has an improved soil thermal model, a new boundary layer scheme, and a correction for non-local thermodynamic equilibrium effects at solar wavelengths....
