The aim of the paper is to determine (on the base of the data of the air temperature from 58 meteorological stations): -the periodical changes (from 1 to 30 years) of the air temperature over Poland within a period of 1951-1990 in the climatological seasons and in the year, -identification of causes of the short-term oscillations of the air temperature - pointed out the synchronous cycles of the air temperature, atmospheric circulation and solar activity. The Boryczka's method of 'regression sinusoids' has been used. The spectral analysis shows that over Poland a few cyclical components with meaningful ranges have been observed. These are cycles: 2-, 3-, 6-, 8-, 10-, 14-16-years. Their presence in all chronological progressions and synchronous (the same periods and phases), particularly 8-years cycle, imply thesis, that periodicity is typical feature of temperature field over Poland. The synchronous (concurrence of periods and coincidence of extremums) of 8- and 11-years component of air temperature changes with the solar activity can testify that solar conditions determine these changes. The researches suppose that periodical changes of the air temperature over Poland are conditioned by the corresponding cycles of atmospheric circulation.
