Weather Radar pictures are now being seen regularly on television. The radar image which the forecasters use helps describe the current situation before they give the forecast. A single Weather Radar can detect the rainfall over a large area, seeing approximately 150 miles in all directions. It is calibrated to determine how much rain is falling as well as where it is falling. By combining the outputs of several strategically placed radars, the results are equivalent to having the whole of the UK and surrounding sea areas covered with rain-gauges. This method o f measuring rainfall has several advantages over established methods: a) It can give total coverage of the area; b) It can measure snowfall as well as rainfall (conventional rainguages do not measure snow); c) It can measure over the sea as well as over land; d) It can give the information in less than 5 minutes.
