Sample monthly means of daily wind anomalies

Following calculations all done with monthly means of daily wind anomalies

following Sardeshmukh and Hoskins 1998
Rossby wave source terms are minus absolute vorticity times divergence and
minus div winds dot-product gradient absolute vorticity, respectively.
