Abstract
The structure and activity of the Siberian Pc air-mass of Winter season in the Far Eastern Asia were studied from the stand point of air-mass theory, especially by Wexler's method, using radiosonde data.
The results obtained by the author are summarized as follows:-
1) The exact height of the Siberian Pc air-mass was determined.
2) A linear relation between height, and temperature of the Siberian Pc air-mass was found. Namely, the temperature of the Pc air-mass decreases as its _??_ight increases.
2) Theoretical, value of the height of the Pc air-mass was also compared with the observed value.
