- Аннотация: Current climate warming is detected not only at the surface air layer but also in the whole of the troposphere. The purpose of this work is to estimate rates of the air temperature changes at different heights in Moscow region. There are three sources of data including TV tower in Ostankino district in Moscow which has a height of 540 m; aerological station in Dolgoprudny town (on a distance 5 km apart the city) and high meteorological mast in Obninsk town having the 310 m height (located on about 100 km to the South from Moscow). The dynamics of the air temperature has been studied for the period from 1991 to 2013 at levels of 2, 121 and 301 m by the data of high mast in Obninsk; at 2, 128, 305, 385 and 503 m by the data of TV tower; and from 2 to 4000 m by the data of radiosondes in Dolgoprudny. As a result of analysis, a total increase of the mean-annual air temperature has been detected at all heights everywhere during last a quarter of century. The growth of mean-annual air temperature was equal to 0.06-0.13 °C/year. A warming in the lower troposphere for this period was more intensive in Dolgoprudny (close to the Northern margin of Moscow) than in Obninsk. This effect can be explained by intensive rate of urbanization at Northern suburbs of Moscow city during last two decades. However, an increase of the air temperature at recent time (several last years) became slower so that a warming deceleration occurs. Besides, air temperature change in the lower troposphere is not the same during the whole year. For instance, a cooling is observed in average from January to March because of cold winters during recent years.
