Statistics of extreme events in weather and climate (e.g. rare floods or strong wind storms) are commonly based on the assumption of Gaussian statistics. Sixty-two years of National Centers for Environmental Prediction / National Center...
Improving lightning cessation forecasts is important to operations of the 45th Weather Squadron (45WS) at Kennedy Space Center (KSC). If lightning advisories can be cancelled closer to the time that cessation actually occurs without...
Past binary logistic regression (BLR) and perfect prognosis schemes have shown skill for predicting the probability of one or more cloud-to-ground (CG) lightning flashes for regions such as Florida. This study examines the ability of the...
The El Nino-Southern Oscillation (ENSO), the North Atlantic Oscillation (NAO), the Pacific Decadal Oscillation (PDO), and the Polar Vortex Oscillation (PVO) produce conditions favorable for monthly extreme temperatures and precipitation....
This study investigates the changes in skewness and kurtosis of five atmospheric variables due to a change in the forcing of a primitive equation global circulation model. First, the average, variance, skewness, and kurtosis are...
During the austral spring months of September and October when biomass burning is prevalent in the Southern Hemisphere, long-range transport can move the biomass burning byproducts from southern Africa to the Pacific Basin....
Scatterometer observations of vector winds are used to examine the amplitudes of synoptic and diurnal cycles. Scatterometers have the advantage of providing global coverage over water; however, irregular temporal sampling complicates the...
This dissertation consists of two complementary major sections. The first is an examination of summertime cyclone transport processes during NASA's Intercontinental Chemical Transport Experiment (INTEX-A) field campaign during Summer...
This study examines the degree of uncertainty that occurs in atmospheric transport and dispersion (ATD) modeling due to using different parameterizations of physical processes such as shortwave and longwave radiative processes, ...
Fourteen years of cloud-to-ground lightning data from the National Lightning Detection Network, and radiosonde releases from Miami and West Palm Beach, are used to develop statistical guidance equations that forecast the amount of warm...
This study presents a new method for assimilating lightning data into numerical models that is suitable for cloud-resolving scales (e.g., 3 km). The study utilized data from the Earth Networks Total Lightning Network at 9 km grid spacing...
This study diagnoses the anomaly fields of the Southern Hemispheric stratosphere in the period from 1 January 2006 to 28 February 2007 and examines the forecasting skill of the NCEP GFS model for the Southern Hemisphere (SH) during this...
