Weird. Seems to be having a problem actually loading the data within iris rather than being a problem in windspharm. Can you try putting the following line before the call to windspharm (line 107 in your script):
ctl_vwnd.data
ctl_w = VectorWind(ctl_uwnd, ctl_vwnd)
This will force iris to load the data for the ctl_vwind
cube, and I'm wondering if this will trigger the same error.

Its Andrew, and yes I think this is a problem with iris, but may be raised because windspharm makes a copy of a cube with deferred data then in-place transposes it (however you seem to be running an older version of iris, I'm not sure this would happen in the most recent version).
You should read up on the deferred loading in iris, but basically when you load a netcdf file (or other format) iris reads the metadata, but doesn't load any data values into memory, it only does this when it needs it. You can force iris to load the data by accessing the .data
attribute as we did here. This makes sense for windspharm, which needs to load all the data anyway so it can be passed to a Fortran library.

I forgot, iris cubes have a method has_lazy_data()
that you can call to see if data is still deferred.
