Pulsation frequencies of acoustic modes are calculated for realistic rotating stellar models using both a perturbative and a two-dimensional approach. A comparison between the...

Sulfur dioxide (SO2) is one of the primary source gases for aerosols in the atmosphere. Even at low concentrations, its presence in the upper troposphere and lower stratosphere...

Mineral dust contributes up to one-half of surface aerosol loading in spring over the southwestern United States, posing an environmental challenge that threatens human health...

The nitric oxide (NO) 5.3 mu m radiative emission is the dominating and most efficient cooling agent in the thermosphere above 100 km. The NO 5.3 mu m radiative cooling is an...

Early radar echo development in trade wind cumulus clouds is studied using the equivalent reflectivity factor Ze combined with the differential reflectivity Zdr. The clouds...

The problem is posed and solved for the oceanic surface boundary layer in the presence of wind stress, stable density stratification, equilibrium wind-waves, and remotely...

We compare new observationally-based data sets of Antarctic near-surface air temperature and snowfall accumulation with 20th century simulations from global climate models...

Tropical carbon emissions are largely derived from direct forest clearing processes. Yet, emissions from drought-induced forest fires are, usually, not included in national-...

A three-dimensional simulation of a supercell storm is performed with a nonhydrostatic model based on a hybrid isentropic-sigma vertical coordinate. The coordinate is a terrain-...

A merger-formation bow echo (MFBE) in southeast China during the pre-summer rainy season (PSRS) was simulated using three microphysics schemes including Thompson (THOM),...

A three-dimensional (3-D) cloud-scale chemical transport model that includes a parameterized source of lightning NOₓ on the basis of observed flash rates has been used to...

This study presents a CO source contribution analysis for the atmosphere of South Asia during January-February 2008. The approach includes into the Weather Research and...

Present-day control and 1% yr⁻¹ increasing carbon dioxide runs have been made using two versions of the Community Climate System Model, version 3.5. One uses the standard...

Convectively induced turbulence (CIT) is an aviation hazard that continues to be a forecasting challenge as operational forecast models are too coarse to resolve turbulence...

Synoptic-scale cyclones in the Arctic are an important source of short-term sea ice variability during the melt season. This study examines whether recent changes to the Arctic...

Identifying the contributions of chemistry and transport to observed ozone pollution using regional-to-global models relies on accurate representation of ozone dry deposition....

This paper describes the effects of time step on the simulation of tropical climate in the NCAR-Community Atmosphere Model version 3 (CAM3). A set of multi-year integrations are...

Emissions of aerosols and their precursors are declining due to policies enacted to protect human health, yet we currently lack a full understanding of the magnitude,...
