of difference between the surface temperature of the Atlantic 

 Ocean in its middle part and its east side is on the whole very 

 good. The principal exception occurs in the year 1908 when the 

 February temperature in Hamburg shows a rise instead of a fall, 

 while the difference between the temperature of the Atlantic Ocean 

 has a maximum. Apart from this the run of the variations of 



Figure 43. Curves : I : Difference between the temperature anomalies for 

 Petersen's stations 5 and 6 and the temperature anomalies of his stations 

 I and 2 for February. II : Corresponding differences between our fields 30° 

 to 39° west longitude and 10° to 19° west longitude. Ill: Anomalies of the 

 surface temperature in February and the year (September to August) at 

 Liepe's station i. IV: Anomalies of the air temperature in Hamburg for 

 February, for the year September to August, and for calendar year. V : 

 Average water level in Swinemunde for the calendar year and for February. 

 VI : Average water level for the calendar year on the Swedish coast. VII : 

 Average water level for the calendar year in Ijmuiden, Esbjerg, and Gjedser. 

 VIII : Average water level for the calendar year in Stavanger and Narvik. 



these curves is in complete agreement. Since the variations in 

 the air temperature in a single mo'nth is naturally much greater 

 than the variations in the surface temperature of the ocean, the 

 scale of the February curve for Hamburg is taken one-fourth as 

 large as the others, as shown to the left in figure 42.
