APPENDIX C: KNUDSEN 



Since the East Icelandic Polar Stream exercises such a great influence on the 

 climate of the Faeroes, the question arises, whether its influence can also reach 

 still further to the south and east. It can be well understood, that this cHmatological 

 influence becomes the less, the further we go from the East Icelandic Polar Stream. 

 To determine the action of the Polar Stream on the cHmate of West Europe would 

 be a very difficult task, demanding considerable material for its solution. I would 

 only remark here, that the winds coming from the Polar Stream in Marchj would 

 cause the air-temperature on the Shetland Islands and west of Scotland to be

ca. 3-5° less than the mean-temperature for this month. This 3-5° is at all events 

 a considerable lowering of the temperature, and it would thus be probable also, 

 that a specially strong flow of the Polar Stream and a corresponding weakening 

 of the Gulf Stream, would lower the air-temperature of the neighbouring countries 

 below the mean-value for considerable periods. If we compare, for example, the 

 position of the boundary-lines representing the 35 °loo isohalin and the 10° isotherm 

 (P^ig. 3), in August 1902 and August 1903, we see that these lines extend much 

 further to the south towards Scotland in 1902 than in 1903. Corresponding to this, 

 there was a characteristic difference in the air-temperatures of Scotland, England 

 and Norway, as the following table shows:
