This study investigated the dust radiative effects on atmospheric thermodynamics and tropical cyclogenesis over the Atlantic Ocean using the Weather Research and Forecasting...

For the first time, vertical column measurements of nitric acid (HNO₂) above Eureka (80.1°N, 86.4°W), Canada, have been made during polar night using lunar spectra recorded with...

We examine hemispheric asymmetry of the annual and semiannual variation of the ratio of O and N-2 concentrations (O/N-2) using observations by the Global Ultraviolet Imager...

Controls on pristine aerosol over the Southern Ocean (SO) are critical for constraining the strength of global aerosol indirect forcing. Observations of summertime SO clouds and...

The interactions surrounding the coupling between surface energy balance and a boundary layer with shallow cumuli are investigated using the National Center for Atmospheric...

A new framework is proposed for the bulk parameterization of rain microphysics: the Bayesian Observationally Constrained Statistical-Physical Scheme (BOSS). It is designed to...

A climatology of cold air outbreaks (CAOs) over North America is presented on the basis of a 50 year simulation of the Whole Atmosphere Community Climate Model (WACCM). This...

A method to predict the bulk density of graupel ρg has been added to the two-moment Milbrandt-Yau bulk microphysics scheme. The simulation of graupel using the modified scheme...

Relationships between rainfall and river discharge are important for governing flood characteristics and predicting flood impacts. Previous studies have examined these...

Small-scale mixing drives the diabatic upwelling that closes the abyssal ocean overturning circulation. Indirect microstructure measurements of in situ turbulence suggest that...

The National Science Foundation's Daniel K. Inouye Solar Telescope (DKIST) will revolutionize our ability to measure, understand, and model the basic physical processes that...

A large-scale model of ocean dynamics finds intermittent behavior that may have implications for how the ocean's energy budget is assessed.

We report a new estimation of the injection of iodine into the stratosphere based on novel daytime (solar zenith angle < 45°) aircraft observations in the tropical tropopause...

Hydrological signatures are now used for a wide range of purposes, including catchment classification, process exploration, and hydrological model calibration. The recent boost...

This document addresses the many issues and problems of online user documentation for supercomputers, specifically, problems of delivering online information in a heterogeneous...

Global ensemble forecasts from The Observing System Research and Predictability Experiment (THORPEX) Interactive Grand Global Ensemble (TIGGE) are used to quantify the magnitude...

Radar imagery of some double-eyewall tropical cyclones shows that the inner eyewalls became elliptical prior to their dissipation during the eyewall replacement cycles,...

Cumulus clouds are common over maritime regions. They are important regulators of the global radiative energy budget and global hydrologic cycle, as well as a key contributor to...

The ionospheric variabilities due to planetary waves (PWs) are complicated due to their nonlinear interaction with tides (migrating diurnal and semidiurnal tides [DW1 and SW2])...
