Context. Recent observations have revealed loop-like structures at very small scales visible in observables that sample the transition region (TR) and even coronal temperatures....

Two high-resolution (4 km) regional climate simulations over a 10-yr period are conducted to study the changes in wintertime precipitation distribution across mountain ranges in...

The impact of atmospheric boundary layer (ABL) interactions with large-scale stably stratified flow over an isolated, two-dimensional hill is investigated using turbulence-...

We quantified the combined effects of mineral dust nonsphericity and size on snow albedo reduction using the MOPSMAP (Modeled optical properties of ensembles of aerosol...

This study evaluates the impact of land surface models (LSMs) and urban heterogeneity [using local climate zones (LCZs)] on air temperature simulated by the Weather Research and...

As the world's population increases, so will the demand for food and timber resources. Though carbon dioxide (CO2) fertilization and, to a lesser extent, nitrogen (N) deposition...

An observed trend in the Southern Hemisphere annular mode (SAM) during recent decades has involved an intensification of the polar vortex. The source of this trend is a matter...

An important source of heating in the mesosphere is the exothermic reaction of ozone with atomic hydrogen, which generates hydroxyl in a vibrationally excited state. Some of the...

We describe the primary observational features of solar cycles, as seen in the photosphere, and review progress made over the past sixty years to simulate and predict these...

Extratropical SSTs can be influenced by the reemergence mechanism, whereby thermal anomalies in deep winter mixed layer persist at depth through summer and are then reentrained...

Monsoon low pressure systems (MLPSs) are among the most important synoptic-scale disturbances of the South Asian summer monsoon. Potential changes in their characteristics in a...

Large wind shears around the mesopause region play an important role in atmospheric neutral dynamics and ionospheric electrodynamics. Based on previous observations using...

A 62-member ensemble of coupled general circulation model (GCM) simulations of the years 1940 - 2080, including the effects of projected greenhouse gas increases, is examined....

Predictions of the Earth system, such as weather forecasts and climate projections, require models informed by observations at many levels. Some methods for integrating models...

Radiative forcing by reflecting (e.g., sulfate, SO₄) and absorbing (e.g., black carbon, BC) aerosols is distinct: the former cools the planet by reducing solar radiation at...

University faculty joined the Developmental Testbed Center (DTC) for a live, virtual 3-day workshop to learn about the capabilities of the DTC's containerized end-to-end NWP...

North American Monsoon (NAM) rainfall is a vital water resource in the United States Southwest, providing 60-80% of the region's annual precipitation. However, NAM rainfall is...

Despite substantial reductions in anthropogenic emissions, ozone (O3) pollution remains a severe environmental problem in urban China. These reductions affect ozone formation by...

This study focuses on the analysis of the extreme precipitation event in Central Nepal on 19 July 2007 which was part of a sequence of rain events leading to the devastating...
