Hail is one of the frequent meteorological disasters all over the world. In order to reduce its economic losses, the prediction of hail cloud has been studied deeply in various countries. Based on the overseas and home experiences, an effective hail cloud recognition model was proposed, which is mainly calculated from the morphological characteristics of the hail and the basic reflectivity factor...
For more than 60 years, Radar data have been used to estimate rainfall rate. But the paradigm is shifting and its applications are being exploited in fields of cloud detection. This paper also takes a step in doing so. Firstly, Radar reflectivity (ZHH) is compared to the occurrence of rainfall and a particular relation between the two is observed. Results are presented to show that rainfall events...
Fog is a significant factor affecting the public traffic because visibility is reduced to a large extent. Therefore the determination of optical visibility in fog from radar instruments has received much interest. To observe fog with radar, high frequency bands (millimeter waves) have the best option. A 35 GHz cloud radar at the Cabauw Experimental Site for Atmospheric Research in the Netherlands...
