“…Some suggest, on the basis of isotopic data, that summer recharge ratios are similar—or greater than—winter recharge ratios (e.g., Caballero et al, ; Darling et al, ; Darling & Bath, ; Gehrels et al, ; Genty et al, ; Kortelainen, ; Lee et al, ; Liu et al, ; Riechelmann et al, ; Van Beynen & Febbroriello, ; Wackerbarth et al, ; Wang et al, ; Williams & Fowler, ; Yonge et al, ). Several of the sites where winter and summer recharge ratios appear similar are places with little intra‐annual variability in precipitation δ 18 O (e.g., United Kingdom: Darling & Bath, ; Darling et al, ) or areas outside of tropical latitudes but still affected by summer monsoons (e.g., southern part of South Korea—Lee et al, ; south‐central China—Wang et al, ; and near Beijing in eastern China—von Rohden et al, ; Liu et al, ). Some of these areas possibly reflect recharge biases to intensive summer precipitation (e.g., von Rohden et al, ; Wang et al, ; section ).…”
