An evaluation of two NEXRAD wind retrieval methodologies and their use in...
Two entirely different methods for retrieving 3D fields of horizontal winds from Next Generation Weather Radar (NEXRAD) radial velocities have been evaluated using radar wind...- publication PDF

The circulation response of a two-dimensional frontogenetic model to...
An analysis of the influence and sensitivity of moisture in an idealized two-dimensional moist semigeostrophic frontogenesis model is presented. A comparison between a dry...- publication PDF

Waldmeier effect in stellar cycles
One of the most robust features of the solar magnetic cycle is that the stronger cycles rise faster than the weaker ones. This is popularly known as the Waldmeier Effect, which...- publication PDF

Sensing climate change using the Global Positioning System
Using simulated atmospheric data from the National Center for Atmospheric Research (NCAR) community climate model (CCM), we test the hypothesis that the global positioning...- publication PDF

Delineating the effect of upward propagating migrating solar tides with the...
Introduction: The vertical coupling of the lower and upper atmosphere via atmospheric solar tides is very variable and affects the thermosphere and ionosphere system. In this...- publication PDF

Flight planning and execution with multiple weather hazards
Today's flight planning aims for safety and efficiency based on the airspace structure, available air routes, and weather. For long-distance flights, wind is of primary interest...- publication PDF

Interaction of superinertial waves with submesoscale cyclonic filaments in...
High-resolution, nearly Lagrangian observations of velocity and density made in the North Wall of the Gulf Stream reveal banded shear structures characteristic of near-inertial...- publication PDF

Multidecadal signal of solar variability in the upper troposphere during the...
Studies based on data from the past 25-45 years show that irradiance changes related to the 11-yr solar cycle affect the circulation of the upper troposphere in the subtropics...- publication PDF

The influence of snow on sea ice as assessed from simulations of CESM2
We assess the influence of snow on sea ice in experiments using the Community Earth System Model version 2 for a preindustrial and a 2xCO2 climate state. In the preindustrial...- publication PDF

Normal modes of atmospheric variability in observations, numerical weather...
MOTIVATION. Normal modes, which we deal with here, are eigensolutions to the linearized primitive equations of the atmosphere. Known as the solutions of the first and second...- publication PDF

Altitude variations of the horizontal thermospheric winds during geomagnetic storms
It is generally assumed that viscosity smooths out vertical gradients of the horizontal thermospheric winds in the upper thermosphere, and thus observations of neutral winds at...- publication PDF
