Özet

We present a validation study for a 50-km resolution version of the RegCM4 regional climate model over the East Mediterranean Basin. In this study, the observation and evaluation of the model results against each other as well as graphication, which mostly generates scatter plot graphs of the atmosphere for operational weather forecasting models (NWP, numerical weather prediction), with 11 different statistical verification score values were evaluated by calculating the regional climate model results. As a result of the analysis, it has been estimated that the rainfall is 42% higher than the estimated average amount RegCM4 simulations based on the 50 observation stations. Meteorological Service (TSMS, Turkish State Meteorological Service) observation network monitored 50 stations based on the average of Frequency Bias Index (FBI), Proportion Correct (PC), Probability of Detection (POD), False Alarm Ratio (FAR), False Alarm Rate (F), Hanssen-Kuipers Skill Score (KSS), the Threat Score (TS), Equitable Threat Score (ETS), Heidke Skill Score (HSS), The Odds Ratio (OR), and Odds Ratio Skill Score (ORSS) values which are as follows, respectively: 0.70, 0.70, 0.52, 0.32, 0.38, 0.39, 0.21, 0.34, 5.99, and 0.69. The objective score values calculated for RegCM4 climate model were found to be close to the score values of the NWP models. Given these values, which were found to be successful for RegCM4 model dynamics, the results generated by other models, recovery/adaptation techniques will be used for the application of hydrological studies.
