- Аннотация: For the first time the long-term dynamics of the urban ‘heat island’ (UHI) intensity over Moscow city has been investigated for the period since 1880s till nowadays using the data of the ground meteorological network. Besides a traditional UHI maximal intensity (i.e. averaged in time difference between the air temperature in the city centre and outside the city) an additional parameter – so-called ‘areal’ or ‘space-averaged’ UHI intensity – has been suggested. It represents a value averaged both in time and in space (a difference between mean air temperature in the city area and outside the city). As it is shown the traditional UHI intensity in Moscow was nearly of 1.0 ºC at the end of the 19th century, 1.3 ºC one century ago, 1.5-1.6 ºC both in the middle, and at the end of the 20th century, and 2.0 ºC at recent years. The ‘areal’ or ‘space-averaged’ intensity was equal to 0.7-0.8 ºC both in the middle, and at the end of the 20th century whereas now, in 2010s, it is about 1.0 ºC. Thus, during several last decades a dynamics of the UHI intensity in Moscow was complicated because both its parameters changed only a bit during the second part of the XX century in spite of monotonous growth of the urban population.
