Isentropic Wind

Isentropic wind is available from the NCEP/NCAR 40-Year Reanalysis CD-ROM on theta surfaces of 315 K, 330 K, and 450 K. Observations are made at 00Z. Overlaid plots including isentropic wind show the isentropic wind at 00Z on the date shown in the plot title. Isentropic wind vectors are made by plotting the vector sum of the zonal and meridional winds, colored by the magnitude of the resulting vector.
