[已解决]想用Grads,grib2资料以风向杆形式绘二维风场，d u;v时出现错误

lingxiyizhi

如题，想用Grads,grib2资料以风向杆形式绘二维风场时，run gs文件后提示如下错误：


附gs文件：
'reinit'
'open D:/test/201301/fnl_20130101_00_00.ctl'
'set grid off'
'set grads off'
'set mpdset cnworld'
'set t 1'
'set lat 32 42'
'set lon 110 120'
'set lev 500'
'set gxout barb'
'd u;v'
;


本人新手，也搜索过论坛里相关的帖子，但是d u;v时始终提示语法错误。跪求各位指导，感激不尽！

你看看你的CTL里面的变量是u 和v么？

ctl里有138个变量，但是我纯菜鸟一个，不知道有没有u和v。我看了一下，与速度有关的如下：

敢问，我应该把gs改成什么？多谢了

改过了，但是还是提示语法错误
