The Climatology and Variability of Eighteen Degree Water Potential Vorticity Forcing
The input of potential vorticity (PV) over the Oceans is estimated from observations to produce a climatological map of PV flux and to study the interannual forcing variability. Particular attention is paid to the North Atlantic subtropical mode water potential temperature range from 17 to 19 ºC. Th...
