Improvement of the WSR-88D Mesocyclone Algorithm
Weather and Forecasting, 1998 Abstract The build 9 Weather Surveillance Radar-1988/Doppler mesocyclone algorithm (B9MA) is designed to locate mesocyclones [rotating thunderstorm updrafts with diameters between 1.8 and 9.2 km (1–5 n mi)]. Because there is less than a one to one correspondence between tornadoes and mesocyclones, the B9MA alerts forecasters when it detects ...

The College Park, Maryland, Tornado of 24 September 2001
Geosciences, 2019 The 24 September 2001 College Park, Maryland, tornado was a long-track and strong tornado that passed within a close range of two Doppler radars. It was the third in a series of three tornadoes associated with a supercell storm that developed in Stafford

Modeling the impact of polar mesocyclones on ocean circulation [PDF]
Journal of Geophysical Research: Oceans, 2008 Subsynoptic polar mesoscale cyclones (or mesocyclones) are underrepresented in atmospheric reanalysis data sets and are subgrid scale processes in most models used for seasonal or climate forecasting. This lack of representation, particularly over the Nordic Seas, has a significant impact on modeled ocean circulation due to a consequent underestimation

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Tornado climatologies over the contiguous United States have traditionally relied on report‐based data sets, which are subject to biases related to population density, time of day, and evolving observational practices. This study presents an object‐based machine learning framework for constructing a tornado climatology using storm cluster data

The observed relationship between tornado intensity and pretornadic mesocyclone characteristics and environments [PDF]
, 2020 Trapp et al. (2017, JAS) used idealized model simulations of supercell thunderstorms to demonstrate support of their hypothesis that wide, intense tornadoes should form more readily out of wide, rotating updrafts.

The Distribution Of Streamwise Vorticity Within The Forward Flank Downdraft And Correlated Low-Level Mesocyclone Changes In A Tornadic Supercell In A High-Resolution Idealized Model [PDF]
, 2023 The results of a large eddy simulation of a tornadic supercell featuring two distinct structures of streamwise vorticity in the forward flank downdraft (FFD) are presented.

Probable Maximum Precipitation: The Smethport Challenge
Water Resources Research, Volume 62, Issue 10, October 2026.Abstract The 18 July 1942 Smethport, Pennsylvania storm produced US and world record rainfall accumulations of 165 mm in 10 min, 240 mm in 25 min and 780 mm in 270 min. Observations from the Smethport storm control sub‐daily Probable Maximum Precipitation (PMP) estimates over a large region of the eastern US.

Mitigation of Wind Turbine Clutter With Digital Phased Array Radar
IEEE Access, 2023 Wind turbine clutter (WTC) contamination affects polarimetric meteorological observations and automatic high-impact weather detection algorithms in several ways, such as, misidentification of precipitation echoes, false mesocyclone detections, and ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.Abstract This study demonstrates an explainable machine learning framework for explicitly selecting important environmental features that determine clusters of right‐moving tornadic supercells. Although previous studies have clustered and analyzed proximity sounding profiles associated with tornadic right‐moving supercells, few have identified key ...
