Over the past few decades, Southeast Australia has experienced severe regional climatic events, including devastating floods and some of the most extreme droughts on record, linked in part to influences from both the El Niño Southern...
Late spring or early summer brings an abrupt onset of a wet season to Peninsular Florida (PF). High daily rain rates are sustained throughout the summer until the demise of the wet season in autumn. Prediction of the Peninsular Florida...
Mesoscale convective systems (MCSs) provide much of the annual rainfall over central equatorial Africa (CEA) during the March-April-May (MAM) and September-October-November (SON) rainy seasons. The characteristics and propagation of...
A combination of observational and numerical analyses is used to investigate hurricane boundary layer (BL) structure in the context of intensity change. These analyses refer to hurricanes in three modes of intensity change: intensifying ...
The state of Florida annually approves 7.4×105 hectares (1.8×106 acres) of prescribed fires, and the production of particulate matter (PM) may cause health issues for neighboring communities. Incomplete combustion of biomass leads to the...
Mesoscale precipitation bands were investigated in 38 winter storms that impacted the northeast US between 2004 and 2015 in the GridRad reflectivity mosaic dataset and compared to simulated bands in the 12 km North American Mesoscale...
The African Easterly Jet (AEJ) is one of the phenomena driving regional as well as global atmospheric circulation. Specifically, within the Sahel region, the AEJ and African Eastern Waves (AEWs) are main features that are linked and...
This study explores extreme surface temperature events in Southern Hemisphere winter (June – August) from 1979 to 2011 and their relation with meridional mass circulation by using daily ERA-interim Re-Analysis data from European Center...
Over the past few decades, numerical weather prediction (NWP) models (and by extension human forecasts) have evolved markedly due to better meteorological understanding, improved observations, data assimilation, physics parameterization, ...
Disorganized, weakly forced convection is a routine summertime occurrence in the Southeast United States. Pulse severe storms are single cell thunderstorms that produce severe wind and/or severe hail for a brief period of time. These...
The impact of including Sea Surface Temperatures (SSTs) of differing horizontal grid spacings in simulations of river and sea breeze related weather has not been studied extensively in the Cape Canaveral area of Florida. This study...
New England (NE) Tropical Cyclones (TCs) can produce significant damage, as well as provide increased forecast track and intensity complexity for forecasters. This is the result of the fact that these TCs recurve, often undergo...
Interactions of Atlantic tropical cyclones (TCs) with upper tropospheric flow are identified in 37 years of ERA-Interim reanalysis data and analyzed from multiple perspectives. Upper tropospheric troughs are identified in a more...
Global models have certain biases that are not yet fully understood. Since they are used to representtropical cyclones (TCs), we need to have a solid understanding of these biases in order to accurately study TCs. The motivation behind...
There is an operational need for accurate tropical cyclone (TC) genesis forecasts. Global numerical models are an important genesis guidance tool, but each model has biases. Further, the interpretation of when genesis occurs in a model...
The size of a tropical cyclone (TC) is a critical structure parameter that is associated with the greatest extent of societal impacts, and it can be estimated by several different metrics depending on the variable used. In this study, a...
Advanced Technology Microwave Sounder (ATMS) has been flying on the Suomi National Polar-orbiting Partnership (NPP) satellite since October 28, 2011. A striping phenomenon contained in the global distribution of O (observations) minus B ...
Physical processes that enhance heavy rainfall in association with warm season (April-September) fronts are investigated over western North Carolina. In this region of complex terrain encompassing the basins of the Upper Catawba River, ...
Lightning inhibits normal operating conditions at the Kennedy Space Center (KSC) and other locations, leading to inconvenience and detrimental economic impacts. Lightning cessation guidance must safely protect lives and infrastructure....
Interactions between clouds, water vapor, radiation, and circulation influence the organization of tropical convection, and the development of tropical cyclones (TCs). This includes the self-aggregation (SA) of convection in idealized...
Interactions between the lower atmosphere and upper ocean on diurnal time scales are assessed in the tropical Atlantic Ocean by combining over 20 years of observations from the Prediction and Research Moored Array in the Tropical...
Florida, in the southeast US, is vulnerable to heatwaves due to its unique geolocation, exacerbated by both high temperature and humidity. To better understand the future impact on heatwave events over Florida we first conduct a...
Electric Potential Gradient Behavior under Shallow Cumulus Clouds Using Electric Field Mills and Cumulus Cloud Top Vertical Growth at Kennedy Space Center and Cape Canaveral Air Force Station
Kennedy Space Center (KSC) at the Cape Canaveral Air Force Station (CCAFS) launches spacecraft for NASA and private companies throughout the year. Since spacecraft are expensive to build and launch, a complicated set of guidelines has...
The ability to construct radial wind profiles of tropical cyclones (TC) from limited observations is crucial to the initialization of TC simulations and predictions. A minimum requirement for constructing a reasonable radial wind profile...
Prescribed fires and wildfires are widespread sources of air pollutants. Prescribed fires, which are used for agriculture, fire hazard reduction, and land clearing, last only several hours and their locations change from one day to the...
Precipitation from atmospheric fronts accounts for a significant portion of the total precipitation in the mid-latitudes, with some locations receiving the majority of their precipitation from atmospheric fronts. In addition, a...
The movement of precipitation around the Earth has an integral impact on fresh water availability, vegetation, and the occurrence of natural disasters, and therefore human society at large. In the African Sahel, the rainfall is the...
The northern Australian rainy season is part of the Asian-Australian monsoon system and occurs during the Austral summer across the northern regions of the continent. The Australian monsoon is responsible for most of the annual rainfall...
ABSTRACT The bias adjustment of visually estimated ship winds in the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) is addressed through the comparison to the QuickSCAT scatterometer equivalent neutral winds. We assume...
The understanding of the evolution of a Tropical Cyclone (TC) has been a topic of research for several years. During the hurricane season not all thunderstorm events embedded in the African easterly waves or otherwise evolve into...
