Starting with WRFDA version 3.1,users have three choices to define the background error convariance(BE)(高端的词汇”背景场协方差“)。We call them CV3, CV5 and CV6. 然后讲 三者之不同和相同点。。。。。。。。
重点是这个 However,CV3(a BE file provided with our WRFDA system) is a global BE and can be used for any regional domain, while CV5 and CV6 BE's are domain-dependent, which should be generated based on the forecast data from the same domain.
后面还有更重要的信息”Theoretically, CV3 BE is a generic background error statistics file, which can be used for any case. It is quite straightforward to use CV3 in your own case. To use the CV3 BE file in your case, set cv-options=3 in &wrfvar7 in namelist.input in your working directory, and use th be.dat is located in WRFDA/var/run/be.dat.cv3“ |
