The Storm Prediction Center (SPC) is developing both a tornadic and severe nontornadic sample of supercell storms from 2014. This latest work is an extension of earlier research which led to the development of conditional probabilities of tornado damage rating from near-storm environment and radar-based storm-scale characteristics from a 5-year sample of tornadoes (4,770) reported in the contig...

Carrier frequencies of networked weather radars are allocated in a narrow band, i.e., in X-, C-, and Sbands. To reduce signal interference among adjacent radars, the carrier frequencies are offset. A calibration procedure, running on radars, brings reflectivity values to the same level assuming that the intrinsic reflectivity of the scattering media is the same. This assumption is good for rain...

The North-eastern part of Italy is known to be one of the most rainy regions in Europe. In this paper three extreme events are analysed, using a multi-sensor observing system including a weather radar and a dense telemetric network of surface stations, recording precipitation, wind, temperature and relative humidity. The cases examined comprise two long lasting rainfall events impacting two dis...
