(A,B) Daily rainfall and potential evapotranspiration (ET0) at the experimental site over 2011–2012 (Modified after Nakhforoosh et al., 2014), and (C) cumulative frequency of occurrence of days with < 50% plant available water (PAW) over 1m soil profile depth during growing season. Calculation based on annual vs. longtime soil water content simulation. Triangles indicate the number of days observed in 2011 and 2012 with < 50% PAW. Dotted line exemplifies interpretation for June 2011: 6 stress days with < 50% PAW means that 56% of years have ≥6 stress days, while 44% of years have < 6 stress days, that means June 2011 is within the wetter half of years for this site.
