TABLE 21. THERMAL WIND ROSES IN SUMMER 



Table 21 (by Vize) presents the typical thermal roses of winds in summer, i.e. , the an- 

 te mperature corresponding to winds of various directions. 



In the last column of the table is shown the temperature amplitude. Vize correctly directs 

 attention to the fact that at coastal stations (on the continent) the amplitude is considerably greater 

 than at island stations. We already know that the water-air temperature difference far off the 

 coast does not exceed ±2°. Therefore, it is natural that a warm or cold wave, crossing the coastal 

 line for the sea, becomes gradually extinguished with distance from the coast. 



TABLE 22. THERMAL ROSES OF WINDS IN WINTER 



Table 22, by Vize, shows the thermal wind roses in winter for certain points of the Soviet 

 Arctic. The amplitudes of temperature fluctuations at various wind speeds are still more signif- 

 icant in winter than in summer; besides, at islands the fluctuations are greater than on the coast of 

 the continent. The air temperature maxima and minima at various coastal points are attended by 

 winds of various directions. 



Figure 12 (by Vize) presents a chart of air temperature anomalies in January. As can be 

 seen from the figure, the positive air temperature anomalies pertain to the Greenland, Barents 

 and Kara Seas. The negative anomalies are found in northeastern Asia. The temperatures that 

 are normal for the given latitudes ( isanomal) intersect the Laptev, East Siberian and Chuckchee 

 Seas. The relative position of heat poles (between Iceland and Norway) and cold poles (about 

 Verkhoyansk) determines the relationship between air temperature and wind direction: with winds 

 from areas with positive anomalies, the air temperature Increases, but with winds from areas 

 with negative anomalies, the air temperature drops. 



It was already stated that the difference between the air and sea surface temperatures in off- 

 shore regions of the ocean is very small. Further it was stated that, due to its great heat capac- 

 ity, the sea, not the air, governs the corresponding temperature equalization. Consequently, if
