[MITgcm-support] add the time dependent wind by 'zonalWindFile'

[Martin Losch]

Hi there,

you've got it right. I do agree that the names of namelist parameters are not always optimal, and sometimes even misleading. I am glad you can now do what you intended to do.

If I setup a wind with a period of one month, then the 'externForcingCycle' should be set '30*24*3600', and the 'externForcingPeriod' can be set '24*3600', which means one value per day. If the time step of the running ('deltaT') is smaller than 'externForcingPeriod', the wind value at each time step will be interpolated.
