The Impact of Surface Heterogeneity on Surface Flux Estimates of the Stable Boundary Layer Using Single Column Modeling
(2022-08)
The surface fluxes of momentum and heat play an important role in the evolution of the atmospheric boundary layer (ABL). Accurate representation of the fluxes in weather and climate forecasting models, especially when ...
60°S-62°S Witnessed a Shift Pattern of Southern Ocean Boundary Layer Aerosols and CCN
(2021)
The Southern Ocean (SO), dominated by high surface wind speeds associated with frequent cyclones, is the most pristine environment on Earth, providing a natural laboratory to study the correlation of marine boundary layer ...
A 20-Year Survey of Short-Duration Extreme Rainfall Events from Summertime Convection Over the Central and Eastern United States: Climatology, Trends, and Meteorological Patterns
(2023-12-15)
Short-duration extreme rainfall events (EREs) caused by convection are often associated with flash flooding, which can have devastating impacts on society. An increase in the frequency and intensity of EREs has been ...
Quantifying and Mitigating Debris-Induced Bias in Radar Measurements of Tornadic Winds
(2021)
The centrifuging of lofted tornadic debris is known to cause bias in Doppler radar measurements of tornado wind speeds. Debris presence in a radar volume is associated with anomalous radial divergence, underestimation of ...
Ice Crystal Size Distributions in Tropical Mesoscale Convective Systems in the Vicinity of Darwin, Australia: Results from the HAIC/HIWC Campaign
(2021-12)
Total ice water content (IWC) derived from an isokinetic evaporator probe and ice crystal size distributions measured by a two-dimensional stereo probe and precipitation imaging probe installed on the French Falcon aircraft ...
Radar analysis of the physics of extreme rainfall events
(2020)
Extreme precipitation events pose a threat to life, property, and economic growth throughout the United States and across the world. Although extensive research has focused on improving understanding of extreme precipitation ...
Structure of tropopause polar vortices represented from the atmospheric profiles of satellite observations
(2022-12-16)
Tropopause polar vortices (TPVs) are sub-synoptic tropopause disturbances commonly found poleward of the polar jet stream. Their roles in cyclogenesis and linkages to mid-latitude weather make them relevant to the improvement ...
Evolution of the Structure and Dynamics of the Nocturnal Low-Level Jet after the Passage of a Cold Front and Insights into the Initiation and Maintenance of Nocturnal Convection
(2021)
Nocturnal low-level jets (NLLJs) are commonly observed over the Southern Great Plains (SGP) and have been linked to occurrence of the nocturnal maximum in mesoscale convective systems over this region during the late spring ...
Impact of Assimilating Ground-Based and Airborne Radar Observations for the Analysis and Prediction of the Eyewall Replacement Cycle of Hurricane Matthew (2016) Using HWRF Hybrid 3DEnVar System
(2021-08-05)
Eyewall replacement cycles (ERC) are common dynamical processes in mature tropical cyclones (TCs) that can result in quick changes to the storm’s intensity and wind field size. As the resolution of TC models increases, ...
Characteristics and Lifecycles of Anticyclonic Tropopause Polar Vortices
(2023-05-12)
Tropopause polar vortices (TPVs) are sub-synoptic, long-lived, closed circulation features located in the upper-troposphere and lower-stratosphere region. Although TPV circulations can be cyclonic or anticyclonic, most ...
