预报准确率 meaning in English
forecast accuracy
forecastaccuracy
Examples
- In contrast with forecasting model without predictor puffing , the prediction accuracy of forecasting model is greatly enhanced
与未采用因子膨化技术建立的预报模型相比，模型的预报准确率有显著的提高。 - The calculating circle is very near compared with the fact . and many physical diagnose quantities thus as high vertical movement , q - vector divergence , 0 - 6 km shear etc . all contact with the rainstorm
在降水场的模拟中，降雨带的范围与实况接近，强降水中心位置和强度略有偏差，通过修正意见对提高预报准确率会有很大帮助。 - The mechanism is difficult to be make out by conventional weather analysis and statistical forecast , and could n ' t find the correspond criterions of these paroxysmal disaster weather forming . these puzzled the forecasters , and leaded to the lower accuracy rate of forecast
传统的天气学和统计方法对这样的突发事件的发生发展机制难以确定，找不到这些突发性灾害天气形成的相应判据，令预报员十分困惑，至今高原地区大到暴雨的预报准确率都很低。 - Numerical weather prediction is an important means in present - day weather prediction . mesoscale model mm5 has been used widely in many observatories . along with a large number of doppler radar stations have been built in our country , it is a crucial problem for the meteorologists how to use doppler radar data in numerical weather prediction model
数值天气预报是现代天气预报的重要手段，中尺度模式mm5在很多气象台得到了广泛应用，随着我国多普勒天气雷达的普及，如何在数值预报模式中使用雷达资料以提高对中小尺度天气现象的预报准确率是摆在广大气象工作者面前的一个重要课题。 - According to his research accomplishments , from 1999 until 2006 , he conducted a series of tests with the liaoning xiuyan ms5 . 6 quake , the inner mongolia ms5 . 9 quake , the sumatra ms8 . 7 quake , the hebei wenan ms5 . 1 quake , as well as the usa california ms5 . 0 quake , to repeat and reoccur the precursors , which indicated a practical earthquake prediction success rate of over 75 %
他依据自己的研究成果，自1999年至2006年先后就辽宁岫岩5 . 6级地震、内蒙古5 . 9级地震、印度洋8 . 7级地城、河北文安5 . 1级地震、美国加州5 . 0级地震等进行了地震前兆的重复和再现性试验，实际预报准确率达75 %以上。
