Figures 50 to 52. Average curves for all fields between 2>1° and 45° north 

 latitude and between 10° and 20° west longitude (fig. 50) ; between 20° and 30° 

 west longitude (fig. 51) and between 30° and 40° west longitude (fig. 52). 

 B: curves for the air pressure gradients for January, for February and for 

 the resultant for both months (indicated by strong dotted lines). W : curve 

 for the anomalies of the surface temperature from February 3 to March 4. 



•■ ^JP/t^ ^°^ ^^^ anomalies of the air temperature from February 3 to March
