MESOCYCLONE OBSERVATION BY MULTI-PARAMETER METEOROLOGICAL RADAR

HYDROMETEOROLOGY AND ECOLOGY. PROCEEDINGS OF THE RUSSIAN STATE HYDROMETEOROLOGICAL UNIVERSITY, 2020
The article deals in detail with the case of observation of a cloud array characterized by a large (15 km) height of the upper boundary of cloud cover and the presence of areas with radar reflectivity of more than 60 dBZ by the DMRL-S meteorological radar installed in Valday (Novgorod region).

Mesocyclone-Targeted Doppler Velocity Dealiasing

Journal of Atmospheric and Oceanic Technology, 2017
AbstractThe alias-robust variational (AR-Var) analysis developed originally for dealiasing raw velocities scanned from winter ice storms by operational WSR-88D radars was recently extended for dealiasing raw velocities scanned from all storms to increase the dealiased data coverage.

Can polar lows be objectively identified and tracked in the ECMWF operational analysis and the ERA-Interim reanalysis? [PDF]

, 2014
Polar lows are maritime meso-cyclones associated with intense surface wind speeds and oceanic heat fluxes at high latitudes. The ability of the ERA-Interim (ERAI) reanalysis to represent polar lows in the North Atlantic is assessed by comparing ERAI and
