This study examines the possibility that winter storms developing off the east coast of Asia may trigger storms developing off the east coast of North American and vice versa. We focus on one point off the northeastern coast of North...
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 ...
Previous case studies have noted a significant extratropical flow response to recurving Atlantic tropical cyclones (TCs), which is often linked to extreme weather events downstream. This study examines the modification of Rossby waves on...
At the polar latitudes, maritime mesocyclones form throughout the year, often near or embedded within cloud streets associated with massive cold air outbreaks. Such storms appear on the 100–1000 km horizontal scale. However, polar...
Simulations are conducted using the Weather Research and Forecasting (WRF) model in a nested domain having horizontal grid lengths of 12 km, 4 km, and 1.33km, in order to establish the dynamic and thermodynamic controls that three...
This study investigates the space-time evolution of the dominant modes that constitute the Asian summer monsoon (ASM), and, as an ultimate goal, the climate prediction of the ASM rainfall. Precipitation and other synoptic variables...
Severe supercell thunderstorms exhibit rotation which aids in organization and maintenance of the storms. The effects of helicity and diabatic heating on the structure of potential vorticity (PV) in a supercell thunderstorm is examined...
With the aid of a 3-part modeling system forced by various satellite-remote sensed atmospheric inputs controlled by cloudiness, this study: (1) describes the space-time variations of surface net CO2 flux exchange over the large scale...
Particle-laden buoyant jets (PBJ) are free-convective flows that contain particles. Many studies have examined pure thermal plumes, discussing a symmetric self-similar structure that is common in the plume literature. Other studies have...
This study investigates the response of the extratropical jet to recurving North Atlantic tropical cyclones (TCs). A joint climatology of north Atlantic recurving TCs from 2007-2013 and Rossby waves on the extratropical jet is presented....
This study looks to examine trends in the annual cycle of Mesoscale Convective System (MCS) activity over Equatorial Africa and the Sahelian region to the north. Convective precipitation features such as these are a vital source of...
Understanding and predicting the inner-core structure and intensity change of tropical cyclones (TCs) remains one of the biggest challenges in tropical meteorology. This study addresses this challenge by investigating the formation, ...
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...
This paper examines the climatology of the major jet steams over West Africa. Three prominent jets occur at varying heights in the atmosphere, and while each jet is zonal in its flow, their sizes, magnitudes, and directions vary greatly....
Atmospheric Mercury Wet Deposition along the Northern Gulf of Mexico: Seasonal and Storm-Type Drivers of Deposition Patterns and Contributions from Local and Regional Emissions
Continuous event-based rainfall samples were collected at three sites throughout the Pensacola airshed from 2005 - 2011. Samples were analyzed for total mercury (Hg), a suite of trace metals (TMs), and major ions in order to understand...
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, ...
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...
Prescribed burning is a land management technique conducted at Eglin Air Force Base (AFB), Florida (FL), by Jackson Guard. Sometimes a fire-induced cumulus cloud, called a pyrocumulus (pyroCu), forms over a surface fire. A towering...
A new methodology has been introduced to detect flash droughts. This method is based off a new variable created called the drought index. This index is calculated using the cumulative daily anomalies of soil moisture, precipitation, and...
