Correlation of long time series of the critical frequencies from European stations of vertical sounding is analysed with respect to latitudinal and longitudinal difference and surface distance of stations. Coefficients are high for raw data, subtracted mean courses but for fluctuations around mean as well. At the surface distance exceeding 1000km and/ or about 10 degrees of latitudinal difference between stations, the correlation coefficient of fluctuations decrease rapidly. As a possible source of the common influence on scale 1000km/10 degree we propose tropospheric systems that are known to be an important source of atmospheric waves in a broad period range. Large tropospheric mesoscale systems have typically up to 2000 km in diameter.
