The 2008 Super Tuesday Tornado Outbreak: Synthetic Dual Doppler Analysis of Contrasting Tornadic Storm Types [PDF]

, 2008
During the Super Tuesday Tornado Outbreak on 5-6 February, a significant number of storms passed within about 40 km of WSR-88D radars. This distance, combined with the significant motion vector (from the southwest at 20-25 m per second) of relatively ...

Evaluation of Clouds in the Conformal Cubic Atmospheric Model Using the CFMIP Observation Simulator Package

International Journal of Climatology, Volume 45, Issue 8, 30 June 2025.
Global map of cloud cover (CC) of CALIPSO‐GOCCP observed (a) total, (b) ice, (c) liquid for 2006–2016. (d–f) and (g–i) same as in (a–c) but for single‐moment (SM‐CCAM) and double‐moment (DM‐CCAM) cloud microphysics. Compared to CALIPSO‐GOCCP, CCAM reasonably captures cloud distribution globally.

Assimilation of Dual‐Pol Radar KDP Observations With the GSI Ensemble Kalman Filter for the Analysis and Prediction of a Squall Line

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 11, 16 June 2025.
Abstract The direct assimilation of dual‐polarization radar observations is realized within the gridpoint statistical interpolation data assimilation (DA) system using the ensemble Kalman filter method. This study involves three experiments designed to evaluate the impacts of assimilating the polarimetric variable specific differential phase (KDP) for ...

VAMA VECHE WATERSPOUTS OF 16 JULY, 2013 [PDF]

Riscuri şi Catastrofe, 2014
Vama Veche waterspouts of 16 july, 2013. As it is known, waterspouts generally occur in unstable thermodynamic stratification, light wind in the low troposphere and high Convective Available Potential Energy (CAPE) in the low layers.

Wavelet Applications for Mesocyclone Identification in Doppler Radar Observations

Journal of Applied Meteorology, 1999
Severe weather often emanates from thunderstorms that have persistent, well organized, rotating updrafts. These rotating updrafts, which are generally referred to as mesocyclones, appear as couplets of incoming and outgoing radial velocities to a single Doppler radar.

Dynamic and statistical analysis of giant hail environments in northeast Italy

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 769, April 2025 Part B.
The hailstorm of record‐breaking hail size that occurred on July 24, 2023 in NE Italy developed in an unusual environment, characterized by moderate instability but intense southwesterly flow and water‐vapor transport in the mid‐troposphere. A high‐Θe tongue over the Adriatic Sea was lifted above a cold pool and fed the storm triggered over the Alps. A

Arctic‐Atlantic Cyclones: Variability in Thermodynamic Characteristics, Large‐Scale Flow, and Local Impacts

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract Cyclones at polar latitudes of the Atlantic‐Arctic corridor exhibit different thermodynamic characteristics. Midlatitude‐origin cyclones, which make up about 14% of wintertime cyclones in the region, are generally warm and moist. The more numerous Arctic‐origin cyclones display a wide range in the boundary‐layer equivalent potential ...

Synthetic discussion on the causes and early-warnings of the first wind-hail strong convection weather over Hunan in 2018

暴雨灾害, 2020
Based on the conventionally observed data, NCEP 6 hourly reanalyzed data, FY-2G satellite TBB data and Doppler weather radar data, we analyze the causes of the first wind-hail strong convection weather process over Hunan on 4 March 2018, and then explore

Synoptic Drivers and Moisture Sources of Snowfall in Coastal Victoria Land, Antarctica

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 4, 28 February 2025.
Abstract Snowfall is an important component of the mass balance of ice sheets and glaciers in Antarctica. In coastal Victoria Land (VL), changes to snowfall can impact ice masses, landscapes, and coastal ecosystems. Coastal VL is characterized by strong gradients in snowfall rates between the polar desert of the McMurdo Dry Valleys and the high ...
