Meanwhile, it is also weak link of the current meteorological work. Took Beibei District of Chongqing as an example, by analyzing issuance of the rainstorm warning signal from 2008 to now, its disastrous weather warning service benefit was evaluated. Result showed that assessment of the disastrous weather warning service benefit should be studied from forecast accuracy, forecast timeliness, forecast coverage and disaster prevention capability.展开更多
