Dear Sir/Madam,
<div class=""><br class="">
</div>
<div class="">I have used the data downloaded from GFS to make the wind field. But I got two different results from Matlab and NCL. For example, there are two blanks in this map of NCL: one is on Greenland, the other is China. But in Matlab, the result is different.
I don’t know whether is there any problem about my NCL codes? I really need your help! Thank you very much!</div>
