A leading hypothesis relating productivity with climate variability in the California Current Ecosystem (CCE) describes an alternation between warmer, well-stratified periods of...

Using information from the A-Train satellites, the properties and radiative effects of eastern Pacific Ocean boundary layer clouds are evaluated in the Community Atmosphere...

Adaptive mesh refinement techniques offer a flexible framework for future variable-resolution climate and weather models since they can focus their computational mesh on certain...

Monthly means of the global sea surface temperature have been produced in the form of composite charts for use with the NCAR general circulation model. These monthly charts are...

The vertical ozone distribution over Boulder, CO has been routinely monitored by the National Center for Atmospheric Research (NCAR) by taking measurements with balloon-borne...

Accurate knowledge of time variation in meridional flow speed and profile is crucial for estimating the solar cycle's features, which are ultimately responsible for causing...

Observations obtained on a relatively small and isolated storm with radar, an instrumented glider and other tools are described. The winds aloft and the direction of motion of...

Soil moisture predictability on seasonal to decadal (S2D) continuum timescales over North America is examined from the Community Earth System Modeling (CESM) experiments. The...

It is well-known that equatorial plasma bubbles (EPBs) are highly correlated to the post-sunset rise of the ionosphere on a climatological basis. However, when proceeding to the...

Cirrus clouds in mid- and high latitudes are frequently composed of bullet rosette- and column-shaped ice crystals, which can have hollow ends. Bullet rosette-shaped ice...

A cell-integrated semi-Lagrangian (CISL) semi-implicit nonhydrostatic solver for the fully compressible moist Euler equations in two-dimensional Cartesian (x–z) geometry is...

On 22 May 2008, a strong tornado—rated EF3 on the enhanced Fujita scale, with winds estimated between 136 and 165 mi h⁻ ¹ (61 and 74 m s⁻ ¹)—caused extensive damage...

The Quasi-biennial Oscillation (QBO) dominates the interannual variability of the tropical stratosphere and influences other regions of the atmosphere. The high predictability...

This study incorporates aerosol effects into satellite radiance calculations within the Global Data Assimilation System (GDAS) to investigate its impact on the analyses and...

The link at 26.5°N between the Atlantic meridional heat transport (MHT) and the Atlantic meridional overturning circulation (MOC) is investigated in two climate models, the...

The necessity and benefits for establishing the international Earth-system Prediction Initiative (EPI) are discussed by scientists associated with the World Meteorological...

Effective climate sensitivity (EffCS), commonly estimated from model simulations with abrupt 4xCO(2) for 150 years, has been shown to depend on the CO2 forcing level. To...

Recommendations are presented regarding the composition and accessibility of the Facilities for Atmospheric Research and Education (FARE), funded by the U.S. National Science...

The nighttime high-latitude stably stratified atmospheric boundary layer (SBL) is computationally simulated using high–Reynolds number large-eddy simulation on meshes varying...

We develop and implement a novel numerical water tracer model within the Noah LSM with multiparameterization options (WT-Noah-MP) that is specifically designed to track...
