which seems to fluctuate but very little, as earlier studies by Schroeder 

 (1963) and Dietrich (1964) also indicate. A detailed dynamical model of 

 the fluctuations in this complex but important area is under consideration 

 at FNWF. 



The atmospheric driving forces (winds) can also cause rapid changes 

 in large-scale sea surface temperature patterns over short periods (few 

 days). This is indicated with the changes off California in Figure 16, 

 the causes of which are obvious from Figure 17. More detailed descrip- 

 tions of these anomaly charts are given by Wolff, Laevastu and Hubert 

 (1964). 



It can be concluded from these and numerous other examples that the 

 oceanographic analyses and forecasts should be done with short period 

 meteorological analyses/forecasts as a basis (e.g., hourly to 6 hourly), 

 and the displays of analyses and forecasts should be made in 12 to 24 

 hour periods in order to indicate significant changes in the oaean. This 

 condition requires that oceanographic analyses and forecasts be made in 

 connection with weather analyses and forecasts and by the same facilities.
