An algorithm based on the self-consistency between the horizontal reflectivity ZH and the specific differential phase KDP has been devised for the calibration of the reflectivity measurements of the McGill S-band dual-polarization radar and implement

An investigation was launched following unexpected observations of step-function transitions in Doppler velocities from scanning radars in regions of high vertical wind shear. It revealed that, if wind velocity transitions are sufficiently sharp and

The MAPLE system has been implemented in real-time in Korea since June 2008, producing forecasts up to 6 hours every 10 minutes. An object-oriented verification method has been applied for the summer season (June–July–August) over the Korean Peni

A Variational Echo Tracking (VET) technique has been applied to four months of archived data from the South Korean radar network in order to examine the influence of the various user-selectable parameters on the skill of the resulting 20-min to 4-h n

The relative skill of two vertical-profile-of-reflectivity (VPR) correction techniques for daily accumulations on a selected dataset and a real-time dataset has been verified. The first technique (C1) adjusts the 1-h rainfall amounts already derived

Errors in surface rainfall estimates that are caused by ignoring the vertical profile of reflectivity (VPR) and range effects have been assessed by simulating how fine-resolution 3D reflectivity measurements at close ranges are sampled by the radar a

Nine summers of reflectivity and Doppler data, (1993–2001), archived by the Marshall Radar Observatory of McGill University have been processed for the purpose of identifying the location, strength and frequency of occurrence of severe weather even

The dependence of the accuracy of short-period radar rainfall accumulations on periodic sampling of the rainfield is investigated. It is shown that errors due to sampling can be greater than all the other errors combined if accumulations are improper

The forecast of radar rainfall rate maps is optimized when the maps to be forecast are averaged over an area A = L2 such that L = kTλ where L is in kilometres, T is the forecast period in minutes, and k and λ are empirical coefficients that are usu

Raingauge data from the 14 July 1987 rainstorm over Montreal are used to underline the reduced errors obtained with a non‐isotropic interpolation scheme. This scheme modifies the geometrical distance between a point and a set of gauges on the basis
