In this study, the relationship between statistical properties (including zonal span, duration, and propagation speed) of warm-season cloud episodes in Hovmollder space and...

Soil moisture is a critical land surface variable, affecting a wide variety of climatological, agricultural, and hydrological processes. Determining the current soil moisture...

The Community Climate System Model, version 4 has revisions across all components. For sea ice, the most notable improvements are the incorporation of a new shortwave radiative...

We use the Multiple Element Limitation (MEL) model to examine responses of 12 ecosystems to elevated carbon dioxide (CO2), warming, and 20% decreases or increases in...

An unprecedented dataset of category-5 Hurricane Isabel was collected on 12-14 September 2003. This two-part series focuses on novel dynamical and thermodynamical aspects of...

The Community Earth System Model, version 1 (CESM1) is evaluated with two coupled atmosphere-land simulations. The CTRL (control) simulation represents crops as unmanaged...

The South Asian summer monsoon is associated with a large-scale anticyclonic circulation in the upper troposphere and lower stratosphere (UTLS), which confines the air mass...

Science gateways provide easy access to domain-specific tools and data. The field of Geographic Information Science and Systems (GIS) uses myriad tools and datasets, which...

Here we describe an updated parameterization for prescribing stratospheric aerosol in the National Center for Atmospheric Research (NCAR) Community Earth System Model (CESM1)....

Precipitation data assimilation has been developed in the Weather Research and Forecasting model data assimilation system (WRFDA) using four-dimensional variational (4D-Var)...

A state-of-the-art Lagrangian microphysics scheme is used in a large-eddy simulation to investigate the stratocumulus transition from closed to open cell structure. Processes...

We use an interannually forced version of the Parallel Ocean Program, configured to resolve mesoscale eddies, to close the global eddy potential energy (EPE) budget associated...

Coral reef ecosystems are threatened by both climate change and direct anthropogenic stress. Climate change will alter the physico-chemical environment that reefs currently...

Simulations with the Global Ionosphere-Thermosphere Model (GITM) show that both Poynting flux and soft electron precipitation are important in producing neutral density...

Since the discovery of the dry ice and silver iodide effects on clouds by Shaefer and Vonnegut in the late 1940s and early 1950s, artificial weather modification operations that...

Organic nitrate (RONO2) formation in the atmosphere represents a sink of NOx (NOx = NO + NO2) and termination of the NOx/HOx (HOx = HO2 + OH) ozone formation and radical...

Seasonal changes in plant leaf area have a substantial impact on global climate. The presence of leaves and the time when they appear affect surface roughness and albedo, and...

The Seoul Metropolitan Area (SMA) has a population of 24 million and frequently experiences unhealthy levels of ozone (O3). In this work, measurements taken during the Korea-...

Organic peroxy (RO2) and hydroperoxy (HO2) radicals are key intermediates in the photochemical processes that generate ozone, secondary organic aerosol and reactive nitrogen...

A lee-wave--rotor system interacting with an approaching cold front in the lee of Pike's Peak near Colorado Springs, Colorado, on 1 April 1997 is studied observationally and...
