but it cannot make any change when I use observation nudging(&fdda).Can everyone help me? I am willing to your reply.

Can you extract U and V from the datafile before and after the nudging, then compare them? Note that the changes after nudging usually are not that big. NCL plots may not demonstrate obvious changes, even if the values are changed.
