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.
