Building on recent observational evidence showing disproportionate increases in temperature and aridity over land in a warming climate, this study examines simulated land-ocean...

Forced interannual-to-decadal variability of annual tropical cyclone (TC) track density in the western North Pacific between 1979 and 2008 is studied using TC tracks from...

In a seminal paper, E. N. Lorenz proposed that flows with many scales of motion in which smaller-scale error spreads to larger scales and in which the error-doubling time...

The tornado outbreak of 21-23 January 2017 caused 20 fatalities, more than 200 injuries, and over a billion dollars in damage in the Southeast United States. The event occurred...

e test the current generation of global chemistry–climate models in their ability to simulate observed, present-day surface ozone. Models are evaluated against hourly surface...

In this paper, the impact of outer loop and partial cycling with the Weather Research and Forecasting Model's (WRF) three-dimensional variational data assimilation system...

Volcanic sulfate aerosols in the stratosphere produce significant long-term solar and infrared radiative perturbations in the Earth's atmosphere and at the surface, which cause...

Over the 21st century changes in both tropospheric and stratospheric ozone are likely to have important consequences for the Earth's radiative balance. In this study, we...

The NCAR Whole Atmosphere Community Climate Model, version 3 (WACCM3), is used to study the atmospheric response from the surface to the lower thermosphere to changes in solar...

The Tibetan Plateau (TP) region experiences strong land-atmosphere interactions, and as an elevated heating source, significantly influences the formation of the Asian monsoon....

Aerosol particles undergo physical and chemical changes during cloud processes. In this work, we quantified the changes in aerosol mixing state using a particle-resolved model....

As climate change increases the frequency and severity of extreme weather events, communities are facing growing vulnerability. Addressing this urgent challenge requires...

In the U.S., over 38,000 fatalities occur every year due to automotive accidents where 24% of these accidents are attributable to inclement weather. Automated driving systems...

The impacts of assimilating meteorological observations on source emissions estimate and chemical simulations are investigated. Using 6-hr Global Forecast System (GFS) analyses...

Four model-error schemes for probabilistic forecasts over the contiguous United States with the WRF-ARW mesoscale ensemble system are evaluated in regard to performance....

Historically, time-split schemes for numerically integrating the nonhydrostatic compressible equations of motion have not formally conserved mass and other first-order flux...

We have derived an analytic form of the thickness redistribution function, Psi, and compressive strength of sea ice using variational principles. By using the technique of...

Land surface models (LSMs) predict how terrestrial fluxes of carbon, water, and energy change with abiotic drivers to inform the other components of Earth system models. Here,...

Extraordinary heat extremes occurred in the 1930s in areas of the Northern Hemisphere far from the record setting heat over the US associated with the Great Plains Dust Bowl...
