In light of rapid environmental change, quantifying the contribution of regional- and local-scale drivers of coral persistence is necessary to characterize fully the resilience...

Hybrid error covariance models that blend climatological estimates of forecast error covariances with ensemble-based, flow-dependent forecast error covariances have led to...

Observed changes in intense precipitation (e.g., the frequency of very heavy precipitation or the upper 0.3% of daily precipitation events) have been analyzed for over half of...

Atmospheric modeling with element-based high-order Galerkin methods presents a unique challenge to the conventional physics-dynamics coupling paradigm, due to the highly...

Numerical experiments in this study show that the tidal wind may have strong impacts on the stability of the gravity wave and therefore significantly affects the breaking of the...

This study reports a very high-resolution (400 m grid-spacing) operational air quality forecasting system developed to alert residents of Delhi and the National Capital Region...

The Terrain-Induced Rotor Experiment (T-REX) is a coordinated international project, composed of an observational field campaign and a research program, focused on the...

Observations from the third campaign of the National Aeronautics and Space Administration Airborne Tropical Tropopause Experiment (ATTREX 3) field mission and Cloud-Aerosol...

It is well established that increasing greenhouse gases, notably CO2, will cause an acceleration of the stratospheric Brewer-Dobson circulation (BDC) by the end of this century....

The National Center for Atmospheric Research (NCAR) Community Climate Model, version 3.6 (CCM3) simulation of tropical intraseasonal variability in zonal winds and precipitation...

Research has suggested that the structure of deep convection often consists of a series of rising thermals, or "thermal chain," which contrasts with existing conceptual models...

Despite the potential influence of iodine chemistry on the oxidizing capacity of the troposphere, reactive iodine distributions and their impact on tropospheric ozone remain...

The authors describe a recent development and some applications of a spectral element dynamical core. The improvements and development include the following: (i) the code was...

A new type of radio occultation (RO) data, recorded in open-loop (OL) mode from the SAC-C satellite, has been tested for monitoring refractivity in the Atmospheric Boundary...

We quantify historical and projected trends in the population exposure to climate extremes as measured by the United States National Center for Environmental Information Climate...

Subgrid information from land models has the potential to be a powerful tool for investigating land-atmosphere interactions, but relatively few studies have attempted to exploit...

Observational data sets in the polar middle atmosphere are extremely valuable for understanding the polar dynamics and coupling between lower and middle atmosphere. Using the...

The National Aeronautics and Space Administration (NASA) has initiated a major program to assess the impact of tropospheric aircraft on the atmosphere. The Subsonic Assessment...

Production of new particles over forests is an important source of cloud condensation nuclei that can affect climate. While such particle formation events have been widely...
