Association of winter weather variability in Central and Eastern North America with tropical Pacific sea surface temperature.
(2006)
The analysis of North American daily precipitation and temperature distributions during warm and cold TP SSTA events identified unique changes. In the southeastern U.S., increased precipitation during January-March warm ...
Northwest Australian Tropical Cyclones: Variability and Seasonal Prediction
(2009)
Global teleconnections, involving geopotential height, air temperature, and sea surface temperature, are found for the interannual variability of tropical cyclone (TC) activity in Northwest-Australian (NWAUS) basin of the ...
Measurements and modeling of the Great Plains low-level jet.
(2003)
This dissertation describes a project to elucidate the turbulent and momentum structure of the Great Plains Low-Level Jet (LLJ), primarily by the use of Doppler radar. Simple theoretical and numerical models of the LLJ are ...
A Regional Modeling Study Of Climate Change Impacts On Warm-Season Precipitation In The U.S.
(2009)
Changes in the character of precipitation have already been observed over much of the United States. In a warming climate, the impacts of these changes will likely be felt most strongly through changes in the intensity and ...
North Atlantic winter surface extratropical cyclone track variability on interannual-to-decadal time-scales.
(2004)
The variability of cyclone activity at interannual and decadal-to-multidecadal time-scales is examined. First, interannual cyclone variability is classified into three major modes based on a VARIMAX Rotated Principal ...
Ensemble Kalman filter assimilation of Doppler radar data for the initialization and prediction of convective storms.
(2006)
Finally, the EnSRF is applied to the May 29-30, 2004 central Oklahoma tornadic thunderstorm case. The initial storm environment is either horizontally homogeneous as defined by a single sounding or is three dimensional as ...
The impact of radar data assimilation on the Chorwon-Yonchon 1996 heavy rainfall event.
(2003)
One of the most effective tools for observing the atmosphere at fine scales is the Doppler radar. In recent years, considerable research has been directed toward using radar data as a component of numerical prediction model ...
Closures of the surface energy budget.
(2000)
Results outline appropriate procedures for limiting instrument and system error in measurement of the surface energy budget. A systematic error was identified from an examination of closure at ten OASIS sites, and a ...
Intraseasonal variability of the North American monsoon over Arizona.
(2004)
Another aspect of intraseasonal variability is the daily persistence of regimes. DR is the most persistent regime, followed by CEMR, NDR, EMR, and CEMSR. Occasionally, sharp changes in storm coverage precede or follow a ...
Ensemble cloud model applications to forecasting thunderstorms.
(2000)
A cloud model ensemble forecasting approach is developed to create forecasts which describe the range and distribution of thunderstorm lifetimes that may be expected to occur on a particular day. Such forecasts are crucial ...
