assumed to be for the geometric center of 

 each quadrangle. Location given on output is 

 actually the corner of the quadrangle and fol- 

 lows this convention: 



Octants 0, 1 - lower right corner 



Octants 2, 3 - lower left corner 



Octants 5, 6 - upper right corner 



Octants 7, 8 - upper left corner 



(Where octant designations conform to Hydro- 

 graphic Office Publication No. 206 code form 

 FM 21.A. "Surface Report From Ship in Full 

 Form.") 



3. Wind vectors -- Wind vectors follow this 

 convention: 



(a) X--vectors run due east and west 

 East--positive 

 West--negative 



(b) Y--vectors run due north and south 

 North- -positive 



South- -negative 



4. Average wind speed --The simple average 

 of all observations irrespective of direction 



Y 2 !. 



( Note - does not necessarily equal 



5. Heat budget computations --The net 

 energy exchange at the air-sea interface. The 

 printout has the following sign convention: 



(a) Energy into sea--positive 



(b) Energy out of sea--negative 



The computer printout labels of various 

 components of the equation are: 



Q(T) - total (net) energy exchange across 

 air-sea interface) 



Q( I ) - incoming solar radiation corrected 

 for cloud cover 



Q(R) - radiation reflected by sea surface 



Q(B) - back radiation 



Q(E) - heat loss or gain through evapora- 

 tion or condensation 



Q(H) - sensible heat conduction between 

 sea and air 



Energy exchange equations will be discussed 

 in subsequent sections of this paper. 



The following notes are given to clarify 

 some aspects of the data: 



1. A blank in heat budget output [ Q(T) , Q(I) , 

 Q(R ), Q(B), Q(E ), Q(H )] is equal to 0. 



2. When any heat budget value [Q(T ), Q(I) , 

 Q(R ), Q(B), Q(E) , Q(H )] is between -1 and 0, 

 a minus sign only appears as entry. 



3. Any entry or a blank followed by (0) 

 means no data for that quadrangle.

 MONTHLY READOUT 



Sea Surface Temperature Charts 



Examples of monthly sea surface tempera- 

 ture charts obtained by using the data 

 summaries and reported in the Bureau of 

 Commercial Fisheries California Fishery 

 Market News Monthly Summary , Part II - 

 Fishing Information are shown in figures 

 7-12. Figure 7 depicts the monthly sea surface 

 isotherm configuration derived from ships' 

 weather reports, average sea temperatures 

 at Weather Ship Stations November and Papa, 

 and average temperatures of coastal stations. 

 Because coastal station data are mailed and 

 must reach the BCF San Diego Laboratory by 

 the first day after the close of a month for proc- 

 essing, the coastal station averages, except for 

 that reported at the pier of Scripps Institution 

 of Oceanography, usually represent only about 

 the first 25 days of each month. Coastal sta- 

 tions included in figure 7 are as follows:
