The influence of sea areas upon mean air temperatures in Fennoscandia (1921-1950)

Abstract

Individual maritimity maps were constructed for each month in the year on the basis of regression analysis. The pattern of the residuals obtained provides indications of the additional influence of factors such as sea water temperature, sea ice, warm and cold advection, cloud cover, snow cover and the major regional climatic factor, the Kölen mountain range, enabling these to be taken into account in the construction of the maritimity maps. The results enable an examination to be made of both the long‑range effects of the Atlantic Ocean and the inland sea area and also the local effects of individual seas. Substantial seasonal fluctuations are to be observed in the regional distribution of maritimity and continentality.
