Despite the importance of groundwater, relatively few studies
have investigated the linkage between groundwater systems and
the large-scale atmospheric circulation (e.g. Anderson and
Emanuel, 2008). Commonly river baseflow has been used as a
groundwater proxy, although in some catchments fluctuations in
groundwater levels have been successfully correlated with low frequency
climate patterns (Holman et al., 2011; El Janyani et al.,
2012). For example, Holman et al. (2011) e
