Urban Heat Island (UHI) phenomenon is well known in scientific literature since first half of the 19th century. By now the climatology of world capitals is described in detail, especially in midlatitudes. In beginning of XXI century new studies focus on heat island of tropical cities due to lack of info about its climatology. However dynamics UHI in Arctic zone and in extreme continental climates is insufficiently investigated, due to the fact that there isn’t large cities in Europe and Northern America within that climate type. In this paper we investigate seasonal and diurnal dynamics UHI intensity for l2 largest cities of Russia, Kazakhstan (including Astana, capital city of Kazakhstan - the second coldest capital city in the world after Ulaanbaatar, Mongolia) and several Arctic cities.
