Two Years of Momentum Flux Data for 31° N

At various times during the past two years, the authors have had occasion to report upon the results of an investigation of the angular momentum balance of the atmosphere as deduced from actual wind measurements dis- tributed over the northern hemisphere (STARR and WHITE 1951, 1952a, 1952b). The nieteoro- logical implications of the results of these studies have been discussed in these papers. A further investigation for a period of one additional year has n ow been completed for 31′ N, in order to verify the previous conclu- sions with independent data. A continuous two-year period has thus been analysed and represents a concluded phase of the investiga- tion for this latitude.
