Glacial changes in tropical climate amplified by the Indian Ocean
The mechanisms driving glacial-interglacial changes in the climate of the Indo-Pacific warm pool are poorly understood. Here, we address this question by combining paleoclimate...- publication PDF

Modeling near-surface turbulence in large-eddy simulation of a tornado: An...
Unsteadiness and horizontal heterogeneities frequently characterize atmospheric motions, especially within convective storms, which are frequently studied using large-eddy...- publication PDF

Description of the UCAR/CU soil moisture product
Currently, the ability to use remotely sensed soil moisture to investigate linkages between the water and energy cycles and for use in data assimilation studies is limited to...- publication PDF

Inhibited upper ocean restratification in nonequilibrium swell conditions
Diurnal restratification of the ocean surface boundary layer (OSBL) represents a competition between mixing of the OSBL and solar heating. Langmuir turbulence (LT) is a mixing...- publication PDF

Toward a physically based gravity wave source parameterization in a general...
Middle atmospheric general circulation models (GCMs) must employ a parameterization for small-scale gravity waves (GWs). Such parameterizations typically make very simple...- publication PDF

Improving ionospheric predictability requires accurate simulation of the...
The mesospheric polar vortex (MPV) plays a critical role in coupling the atmosphere-ionosphere system, so its accurate simulation is imperative for robust predictions of the...- publication PDF

Low‐latitude zonal ion drifts and their relationship with subauroral...
We analyze horizontal plasma drifts measured by the Defense Meteorological Satellite Program satellites during two intense magnetic storms. It is found, for the first time, that...- publication PDF

Improving vortex position accuracy with a new multiscale alignment ensemble filter
A multiscale alignment (MSA) ensemble filtering method was introduced by Ying to reduce nonlinear posi-tion errors effectively during data assimilation. The MSA method extends...- publication PDF

An updated Antarctic melt record through 2009 and its linkages to...
A 30-year minimum Antarctic snowmelt record occurred during austral summer 2008-2009 according to spaceborne microwave observations for 1980-2009. Strong positive phases of both...- publication PDF

North Atlantic climate far more predictable than models imply
Current models are too noisy to predict climate usefully on decadal timescales, but two-stage post-processing of model outputs greatly improves predictions of decadal variations...- publication PDF

BVOC-aerosol-climate interactions in the global aerosol-climate model ECHAM5.5-HAM2
The biosphere emits volatile organic compounds (BVOCs) which, after oxidation in the atmosphere, can partition on the existing aerosol population or even form new particles. The...- publication PDF

Modulation of shallow-water equatorial waves due to a varying equivalent...
The dynamics of convectively coupled equatorial waves (CCEWs) is analyzed in an idealized model of the large-scale atmospheric circulation. The model is composed of a linear...- publication PDF

Can atomic oxygen production explain the ionospheric annual asymmetry?
The causes of the ionospheric annual asymmetry, which refers to a larger averaged electron density at geomagnetic conjugate latitudes in December than in June, remain an...- publication PDF
