A new empirical parameterization (EP) for multiple groups of primary biological aerosol particles (PBAPs) is implemented in the aerosol-cloud model (AC) to investigate their...

A theoretical framework has been developed describing nonequilibrium formation and maintenance of mixed-phase clouds. The necessary and sufficient conditions required to...

Improved estimates of NOx from lightning sources are required to understand tropospheric NOx and ozone distributions, the oxidising capacity of the troposphere and corresponding...

Simulation of key features of the Arctic atmosphere in the Community Climate System Model, version 4 (CCSM4) is evaluated against observational and reanalysis datasets for the...

Solar activity during 2007-2009 was very low, and during this protracted solar minimum period, the terrestrial thermosphere was cooler and lower in density than expected....

To investigate the features of the extremely deep atmospheric boundary layer (ABL) over the Taklimakan Desert (TD) and its influence, this paper utilizes sounding data obtained...

Bright auroral emissions during geomagnetic storms provide a good opportunity for testing the proposal that substorm onset is frequently triggered by plasma sheet flow bursts...

Under the protocols of phase 3 of the Paleoclimate Modelling Intercomparison Project, a number of simulations were produced that provide a range of potential climate evolutions...

Recent work suggests that natural variability has played a significant role in the increase of Antarctic sea ice extent during 1979-2013. The ice extent has responded strongly...

Despite the large energy input from surface evaporation, the moist static energy (MSE) of the tropical boundary layer remains relatively constant on large spatial and temporal...

This research evaluates the climatic summertime representation of the diurnal cycle of near-surface temperature using the Weather Research and Forecasting System (WRF) over the...

Frozen cloud particles are an important component of the hydrological cycle and significantly influence the Earth's energy budget. Despite their important role, observational...

Policies for climate mitigation on land rarely acknowledge biophysical factors, such as reflectivity, evaporation, and surface roughness. Yet such factors can alter temperatures...

By using a compressible nonlinear two-dimensional gravity wave model, we simulate the nonlinear interactions between gravity waves (GWs) with three different vertical...

This report explains questions and builds upon previous findings on the comparison of quasi-geostrophic and primitive equation models for stratospheric sudden warming simulations.

Aerosol optical depths (AODs) used for the Edition 4.1 Clouds and the Earth's Radiant Energy System (CERES) Synoptic 1 degrees (SYN1deg) product are evaluated. AODs are derived...

Estimates of the anthropogenic effective radiative forcing (ERF) trend have increased by 50% since 2000 (from +0.4 W m(-2) decade(-1) in 2000-09 to +0.6 W m(-2) decade(-1) in...

Motivated by low-altitude cusp observations of small-scale (similar to 1 km) field-aligned currents (SSFACs) interpreted as ionospheric Alfven resonator modes, we have...

Accurately modeled biogenic volatile organic compound (BVOC) emissions are an essential input to atmospheric chemistry simulations of ozone and particle formation. BVOC emission...
