Atmospheric Superrotation in Warm Earth Climates
(2014-02-25)This thesis considers atmospheric superrotation, a state of westerly equatorial winds which must be maintained by up-gradient eddy momentum fluxes. Superrotation has appeared in simulations of warm climates that generate ... -
Climatic Drivers of Hemispheric Asymmetry in Global Patterns of Ant Species Richness
(Blackwell Science, 2009)Although many taxa show a latitudinal gradient in richness, the relationship between latitude and species richness is often asymmetrical between the northern and southern hemispheres. Here we examine the latitudinal pattern ... -
A High-Latitude Convective Cloud Feedback and Equable Climates
(Royal Meteorological Society, 2008)A convective cloud feedback on extratropical surface temperatures is identified in a zonally averaged two-level atmospheric model. The model contains simplified parametrizations for convection, precipitation, and clouds, ...
