Investigating Arctic Cyclone-Tropopause Polar Vortex Interactions with Observing System Simulation Experiments
(2023-05-12)
Tropopause polar vortices (TPVs) are upper-level cyclonic circulations that are common in high latitudes. TPVs most directly impact weather at the surface by providing baroclinic forcing for the development of Arctic ...
Subseasonal Variability of Biomass Burning Aerosol Radiative Properties Retrieved by 4STAR during the ORACLES 2016-2018 Campaigns
(2022-05)
Absorbing aerosols play a role in cloud and radiation processes, but these interactions are complex and have a high degree of uncertainty. The interactions of Biomass Burning (BB) aerosols with the semipermanent subtropical ...
Examining Meteorological Benefits of Rapid-Scan, Dual-Polarization, All-Digital Phased Array Radar Observations for Detecting Tornado Formation and Intensification
(2022-08-04)
Phased array radar (PAR) is widely considered the future for a replacement to the current operational radar network, NEXRAD. In particular, an all-digital operational PAR network offers a range of benefits including adaptive ...
The Seasonality of Madden-Julian Oscillation (MJO) Teleconnections
(2023-08-04)
The Madden Julian Oscillation (MJO) is a tropical intraseasonal phenomenon that is known to generate teleconnections like the Pacific North American and the North Atlantic Oscillation patterns in boreal winter, but knowledge ...
A Comparative Convective Study Between the Ensemble Kalman Filter and the Local Particle Filter Using the Gridpoint Statistical Interpolation System
(2020-07-30)
The localized particle filter (LPF) is a recent advance in ensemble data assimilation for numerical weather prediction. Derived from the original particle filter used for highly nonlinear state variables, the LPF incorporates ...
Meteorological Benefits of Dual-Polarization, Rapid-Scanning Radar Systems on Hail Producing Storms
(2022-08-04)
Hailstorms continue to be one of the leading economic natural hazards in the United States, amounting to ten billion dollars in damage, on average, annually. Radar tech- nology is one of the best means of detecting hailstorms, ...
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 ...
