PBL plays a critical role in the atmosphere by transferring heat, moisture, and momentum. The warm PBL has a distinct diurnal cycle including daytime convective mixing layer...

Atmospheric models used for weather prediction and future climate projections rely on landmodels to calculate surface boundary conditions. Observations of near-surface states...

To help understand potential effects of urbanization on climates of varying scales and effects of climate change on urban populations, urbanization must be included in global...

Climate change affects the dynamics and thermodynamics of moist convection. Changes in the dynamics concern, for instance, an increase of convection strength due to increases of...

In this paper we show how multiple data sets, including observations and models, can be combined using the "three-cornered hat" (3CH) method to estimate vertical profiles of the...

Chemical and biological (CB) defense systems require significant testing and evaluation before they are deployed for real-time use. Because it is not feasible to evaluate these...

Uncertainties in aircraft inertial navigation system and radar-pointing angles can have a large impact on the accuracy of airborne dual-Doppler analyses. The Testud et al. (THL)...

Advanced microphysics schemes (such as Eulerian bin and Lagrangian superdroplet) are becoming standard tools for cloud physics research and parameterization development. This...

Collisionless shocks can be nonstationary with periodic reformation shown in many simulation results, but direct observations are still tenuous and difficult to conclusively...

As part of the WINTER (Wintertime Investigation of Transport, Emissions, and Reactivity) campaign, a Particle-into-Liquid Sampler with a fraction collector was flown aboard the...

Each day the Global-scale Observations of the Limb and Disk imager observes the equatorial ionization anomaly (EIA) near sunset from similar to 10 degrees E to similar to 80...

In recent years, severe haze events often occurred in China, causing serious environmental problems. The mechanisms responsible for the haze formation, however, are still not...

Conditional composites of dropsondes deployed into eight tropical Atlantic weather systems during 2010 are analyzed. The samples are conditioned based on cloud-top temperature...

A recently developed chemical ionization mass spectrometer for detecting neutral molecular clusters in the atmosphere (the Cluster-CIMS) is described. This instrument is unique...

Lagrangian Cloud Model (LCM) is a mixed Eulerian/Lagrangian approach to atmospheric large eddy simulation (LES), with two-way coupling between Eulerian dynamics and...

The extratropical upper troposphere and lower stratosphere (Ex-UTLS) is a transition region between the stratosphere and the troposphere. The Ex-UTLS includes the tropopause, a...

In this study, the influence of climate change to California and Nevada regions was investigated through high-resolution (4-km grid spacing) dynamical downscaling using the WRF...

Geophysical fluid flows are predominantly turbulent and often strongly affected by the Earth's rotation, as well as by stable density stratification. Using direct numerical...

This study quantifies future changes in tropospheric ozone (O3) using a simple parameterisation of source–receptor relationships based on simulations from a range of models...

Catastrophic failures in the built and natural environment resulting from climate extremes such as flooding have become all too familiar. Limit state design under changing...
