Radar Studies of Rainfall with Applications to Forecasting

天气监测雷达被用来预测恶劣天气事件，回声强度取决于波束中的雨滴数量。通过适当的校准，回波强度可以用来预测降雨率。2005年，气象局将在阿德莱德附近建立一个新的天气雷达。我们将把新雷达的降雨量估计与VHF剖面仪的结果进行比较，VHF剖面仪可以准确地测量雨滴分布和降雨量。其目的是测试天气雷达对降雨率的估计及其不确定性。研究成果将在洪水预报和水文学中得到应用。

Weather watch radars are used to predict severe weather events, with echo strengths depending on the number of rain drops in the beam. With suitable calibration the echo intensities can be used to predict rainfall rates. In 2005 the Bureau of Meteorology will establish a new weather radar near Adelaide. We will compare rainfall estimates made with the new radar with results from a VHF profiler that accurately measures rain drop distributions and rainfall. The aim is to test the weather radar estimates of rainfall rates and their uncertainties. Outcomes will have applications in flood forecasting and hydrology.
