For the general climatology analysis of GWSA and the climatic variables in the study area, the average of the long-term monthly values of GWSA, precipitation and temperature were calculated and plotted to evaluate the long-term monthly interactions of each variable with GWSA. The temporal interactions of climatology values of GWSA and climatic variables of precipitation and temperature in 2-month lagged time step are illustrated in figures 11 and 12. The correlation between climatology variables was found to be the highest in 2-month lags for the study area. Figure 13 depicts the comparison of the mean annual correlations found between monthly GWSA and climatic variables. It is revealed that the variations of groundwater in the study area interacts more strongly with temperature. Therefore, it can be said that temperature increase plays a more dominant role on the variations of groundwater storage over Turkey. Summary of the regression statistics of the temporal values is shown in Table 2. According to the climatology graphs, it is understood that the least amount of groundwater storage [- 11.5 cm] happens on August, which corresponds to the least amount of precipitation and highest temperature for the general prevailing climatic conditions in Turkey. The max storage of groundwater [10.76 cm], on the other hand, occurs on February, which correspond the mid-winter conditions with high precipitation and infiltration values.
