variability in summer. A few irregular values result from poor datao 
This outcome is favorable since it permits analysis without reference 
to seasono As the next. step, the monthly anomalies were plotted on time eco~ 
tions for all squares and curves drawne Poor values usually could be located 
easilye Most often a large positive or negative anomaly appeared in a single 
month in one square without history either in that or surrounding squares. 
Such values were disregarded. Except for such irregular values (and the years 
of World War I) little smoothing proved necessarye Hspecially in the later 
years when date was most plentiful in many squeres, anomaly variations becane 
very regular and consistent. The time sections could be used to fill in oeca- 
sional gaps of one or two months in a records 
From the curves adjusted monthly anomaly values were plotted on charts. 
These charts are reproduced as the main part of this reporte The anomalies 
are in tenths degrees Fahrenheit 9% 
The charts can be analyzed with some efforts Enough irregularity, how- 
‘ ever, is left to suggest another smoothing. This was done by preparing a set 
ef charts with four-square overlapping meanse This new set could be analyzed 
with great easee It shows pronounced anomaly centers which sometimes persist 
for many months and usually, though not always, travel on a clockwise path 
through the ocean. Unfortunately, these charts could not be prepared for ail 
years because of the small number of squares available in many of the yearse 
Hence it was decided to reproduce the original set of charts which contains 
no analysis but all datae 
: Due to the large number of charts the data could not be drafted for 
reproduction. Apology is made for the occasional values which are difficult 
to reade Underlined numbers: less than ten observations.
