Abstract : The yearly amplitude of the temperature at Moscow (July to January) was calculated for 140 years, starting from 1821, since from that year on there have been no gaps in the published data for the mean monthly temperature at Moscow. The integral curve of yearly amplitudes constructed from these data (by summing the departures from the long-term means) shows that the variations of continentality fall into four well-expressed periods, mainly reflecting fluctuations in the January temperature: (1) From the end of the 1820's to the beginning of the 1860's, a period when there prevailed stable high indices of continentality, due to a low January temperatures; (2) from the beginning of the 1860's to the end of the 1890's the continentality was subject to brief fluctuations in either direction, with a slight falling trend; (3) from the end of the 1890's to the middle of the 1920's there was observed a period of markedly declining continentality, due to just as marked a rise of the January temperature, and also a quite considerable fall of July temperature; and (4) from the middle of the 1920's until 1960 the continentality underwent fluctuations in either direction, with a slight rising trend.
