VARIABILITY OF SOIL SURFACE TEMPERATURE IN THE CÂMPULUNG MUSCEL DEPRESSION (ARGEŞ - ROMANIA)

Abstract

In the Câmpulung Muscel Depression, the soil surface mean annual temperatureover the past 40 years was 8.5°C, ranging between 7.3°C and 10.4°C. During the year, the temperature of the soil surface was similar to air temperature, except the higher amplitude of the warmest month and the coldest month. The monthly minimum means of the soil was below the monthly minimum means of the air and, except for the months of January and December, themaximum mean was higher than the maximum mean of the air. The absolute minimum temperature of soilsurface was -33.0°C (February 19, 1985), and the absolute maximum was 56.8°C (July 2, 2003). In the Câmpulung Muscel Depression, the last spring frosts and the first autumn frosts were the risk phenomena after May 1 and before October 5. The mean annual number of frost days on the ground was between 14.7 days in the decade 2001-2010 and 165.7 days in the decade 1981-1990.
