Determining the Characteristics of Anvil and Thunderstorm Lightning for Use in the Lightning Launch Commit Criteria at Cape Canaveral Air Force Station and Kennedy Space Center
The 45th Weather Squadron (45WS) provides weather support to America's space program at Florida's Cape Canaveral Air Force Station (CCAFS), Kennedy Space Center (KSC), and Patrick Air Force Base (PAFB). Since CCAFS/KSC lies within...
The global climate has been experiencing significant warming at an unprecedented pace in the past century1, 2. This warming is spatially and temporally non-uniform, and one needs to understand its evolution in order to better evaluate...
The growth of a locally isolated strain of green algae, Chlorella sp., selected for its promise as a biodiesel feedstock, was studied in wastewater effluent from the municipal wastewater treatment plant in Tallahassee FL. Nutrient...
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...
The sporadic nature of lightning in tropical cyclones (TCs) is a topic of great interest to researchers and forecasters. This study explores relationships between lightning, cloud microphysics, and TC storm structure in rapidly...
In the western North Pacific basin, several agencies archive "best track" data of tropical cyclones. The Joint Typhoon Warning Center (JTWC) in Hawaii is responsible for the issuance of tropical cyclone warnings for United States...
Gravity measurements from the Gravity Recovery and Climate Experiment (GRACE) satellite measuring system show that Greenland is losing mass as water is lost to the ocean. Past work has suggested that the freshwater flux from Greenland, ...
This study presents a new algorithm to dealias folded Doppler velocities in S, C, and X-Band radars using a new boundary detection technique on the raw velocity field as a whole, rather than the traditional gate by gate methodology used...
The Cartersville area in Georgia lies at the junction between the Alabama Recess and the Tennessee Salient. The rocks here are the easternmost exposures in the foreland fold and thrust belt of the southern Appalachians. It is bounded to...
To evaluate the influence of dietary carbon on fish otoliths, juvenile red drum (Sciaenops ocellatus) were raised for 6 and 9 months in tanks with flow-through ambient seawater and fed diets differing by 2.12‰ (p < 0.001) in carbon...
In the uppermost millimeters of shallow marine sands, photosynthesis by microalgae can cause oxygen supersaturation, leading to formation of oxygen bubbles and subsequent ebullition of the gas from the sediment. The role of ebullition...
Naturally-occurring radioisotopes are ubiquitous in nature, and as such, there are many opportunities for researchers to use them as environmental tracers. Their associated radioactive decay rates provide an inherent time clock that...
Warm seclusions are large midlatitude storms that have the potential to substantially influence the turbulent heat fluxes and global energy budget. These storms have not been previously investigated from an energy and flux perspective....
The goal of this investigation was to determine whether highly accurate sampling and dating methods could be employed to develop a high-resolution history of barrier evolution and sea-level change. The focus of the study was St. Vincent...
The δ13C value of foliage respiration has been considered a constant in the past and modeling efforts have assumed that the δ13C value of foliage respiration is constant and is directly related to substrate without any fractionation....
Rates of U(VI) release from two field-aggregated and contaminated composite sediments were collected from the seasonally saturated lower vadose zone of the US Hanford 300 Area were examined in stirred flow-cell reactors. Kinetic U(VI)...
This study focused on the combined use of radon and radium isotopes as tracers of near-shore geophysical processes including submarine groundwater discharge (SGD), water exchange rates, and atmospheric evasion. Methods were developed for...
The Asian summer monsoon is a dominant feature of the global circulation. The upper-level anticyclone (ULAC) associated with the Asian summer monsoon circulation stands out vividly in satellite observations of trace gases. The ULAC also...
A robust dune system is one of the principal factors in the protection of recreational and residential property within barrier islands. Storm surge from significantly large storm events may remove some or all of the dunes during overwash...
The isotopic composition of species-specific atmospheric mercury (Hg) was investigated in the coastal environment of Grand Bay, Mississippi, USA. Hg0(g), HgII(g) and Hg(p) were concurrently separated and collected, and subsequently...
Calcareous nannofossils are used as biostratigraphic indicators integral for age control in both petroleum industry and academic settings. The Oligocene and Late Cretaceous are especially problematic for nannofossil biostratigraphers due...
The need for a high-resolution precipitation database over Florida is evident by the ever-increasing impact of water resources on society. The Multisensor Precipitation Estimator (MPE) software was developed by the National Weather...
The ice shelves in the Western Antarctic have seen an increase in melt over the past decade, mainly due to basal melting induced by underlying warm, salty Circumpolar Deep Water. Seal data in the Bellingshausen Sea provides extensive...
ABSTRACT High-resolution biostratigraphic data were collected from two cores drilled in 2007 and 2009 by the United States Geological Survey at the South Dover Bridge (SDB) and the Cambridge-Dorchester (Cam-Dor) Airport in eastern...
Trace metals are important compounds in aquatic environments. In low concentrations, they can be very beneficial to aquatic life. However, they can be toxic if present in moderate to high concentrations. A growing interest has occurred...
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...
Large amplitude internal waves are a long recognized feature of the South China Sea. Remote sensing imagery often shows the sea-surface manifestation of these waves as they radiate from the Luzon passage into the deep water of the South...
Carbon isotopes were used as tracers in the Florida Everglades to investigate the sources and sinks of dissolved organic carbon in natural and constructed wetlands and provide a way to monitor ecosystem restoration efforts. Stable carbon...
