WAM winds seems to be too strong

[twfang]

In the new repo, we are now able to obtain neutral winds at geographic coordinates that are seen by the IPE. During the process, the neutral winds were plotted out. However, the magnitudes of these winds seems to be too strong during a quiet conditions and are need to be re-evaluated.

I have compared the plots with the WAM native outputs and other WAM run provided by Zhuxiao, the problem is consistent and is not related to the post-processing package.

Below figure shows the WAM winds at 350 km.

Compare to the CTIPe output on 2017-03-15 at around 300km, WAM winds seem to be very large.

@twfang I rechecked the wind in WAM, the following is some 2D T&wind map during some 'quite' time.

for the 2013-03-17 storm, GOCE cross track wind (~250km) is available: see fig 1 in this paper

Double checked U and V at 350km in WAM during quite time respectively, their pattern seems similar with above, except the max area is more north towards and sheer is not that narrow & large.
Post the following plots as the reference later.
