Özet

Precipitation is a meteorological data exhibiting large variations both temporally and spatially. There are quite a few research publications in literature related to temporal variation of precipitation. In this study, the spatial variation of seasonal precipitation is investigated using the monthly precipitation data measured all over Turkey. For this purpose, the monthly average values pertaining to the January December period based on recorded data of at least 20-year length observed at 200 rain-gauging stations existing four seasons can be depicted by a Gaussian type semivariogram and the spatial variation of seasonal precipitation can be estimated by this geostatistical method at sufficient accuracy. The outcome of the study enables the magnitude of seasonal precipitation at ungauged geographical locations to be estimated easily with sufficient accuracy.
