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

Sensitivity of mountain wave drag estimates on separation methods and...
Internal gravity waves (GWs) are ubiquitous in the atmosphere, making significant contributions to the me-soscale motions. Since the majority of their spectrum is unresolved in...- publication PDF
