The very stable boundary layer on nights with weak low-level jets
The light-wind, clear-sky, very stable boundary layer (vSBL) is characterized by large values of bulk Richardson number. The light winds produce weak shear, turbulence, and...- publication PDF

Influence of continental ice retreat on future global climate
Evidence from observations indicates a net loss of global land-based ice and a rise of global sea level. Other than sea level rise, it is not clear how this loss of land-based...- publication PDF

Improvements in a half degree atmosphere/land version of the CCSM
A decadal climate projection between 1980 and 2030 using a nominal 0.5° resolution in the atmosphere and land components has been performed using the Community Climate System...- publication PDF

Exploring the radial evolution of interplanetary coronal mass ejections...
Context. Coronal mass ejections (CMEs) are large-scale eruptions coming from the Sun and transiting into interplanetary space. While it is widely known that they are major...- publication PDF

Climatology of the planetary boundary layer over the continental United...
Although boundary layer processes are important in climate, weather and air quality, boundary layer climatology has received little attention, partly for lack of observational...- publication PDF

The future of the El Niño-Southern Oscillation: Using large ensembles to...
Future changes in the El Nino-Southern Oscillation (ENSO) are uncertain, both because future projections differ between climate models and because the large internal variability...- publication PDF

A study of aerosol impacts on clouds and precipitation development in a...
Aerosols influence cloud and precipitation development in complex ways due to myriad feedbacks at a variety of scales from individual clouds through entire storm systems. This...- publication PDF

Attribution of decadal variability in lower-stratospheric tropical ozone
The variability of ozone in the lower stratosphere in a climate-chemistry model is investigated by multiple regression analysis. The model includes forcing due to changes in...- publication PDF
