NO. 4 TEMPERATURE VARIATIONS IN THE NORTH ATLANTIC 



8l 



In the same figure is given a curve for the temperatures ot the 

 air for February in Hamburg (according to Thraen, 1915). The 

 scale is here also inverted. The agreement between this curve and 

 the February curve for Liepe's station i and also for the curves

Figure 42. Curves for : Average difference between the temperature 

 anomalies of the fields 30° to 39° west longitude and the fields 10° to 19° west 

 longitude (the upper curves are the means of the curves of figure 41) for 

 February; anomalies of the surface temperatures for February and for the 

 year (September to August) at Liepe's station i; anomalies of the air tem- 

 perature for February and the calendar year in Hamburg; anomalies of the 

 air temperature for the calendar year in northwest England, on the English 

 Channel, in Vliessingen, and Borkum ; water level for the calendar year in 

 Gjedser, Korsor, Esbjerg, and Swinemunde. For the temperature curves 

 and the water level curves the scales are inverted.
