MOISTURE INDEX IN THE FIELD OF KOSOVO

The study to determine the magnitude of the moisture index was done in the region of “The Field of Kosovo”, having Prishtina as the position where the data are collected and the measurements are done. The data collected from the central meteorological station of Kosovo. The data collected are sun radiation, relative humidity, wind speed and temperature, necessary to be used for potential evapotranspiration calculation (Gjongecaj B., 1998; Monteith,J. L., 1965; Penman, H.L., 1948). A particular computer program was adjusted to convert automatically the above data measured by the devices into potential evapotranspiration, expressed as mm evaporated water per day, calculated based on the Penman-Monteith formulae (Monteith,J. L., 1965; Penman, H.L., 1948). The precipitation was also registered parallely with the abovementioned climatic parameters. Both, potential evapotranspiration and precipitation were used to characterize the climate of region from the humidity or aridity point of view, based on the prevailing either water deficiency or water surplus. By combining both climatic parameters, ETp (evapotranspiration) and R (precipitation) were combined, as it seen in the (Thornthwaite W. C., 1948) to determine both: the moisture ratio Mr and the index of moisture, Im. The latter is considered to be the most important one to characterize the climate from either the humidity or aridity. The classification invented by Thornthwaite region was used to classify in each month and for the entire period of an average year, it was classified as humid.
