“…In fact, sub-seasonal forecast information can be useful for developing strategies for proactive natural disaster mitigation (Brunet et al, 2010;Vitart et al, 2012). Previous studies have evaluated the potential of sub-seasonal to seasonal forecasts for heat wave forecasting (e.g., Hudson et al, 2011a;White et al, 2014), hydrological forecasting (e.g., Orth and Seneviratne, 2013;Yuan et al, 2014), water resources management (e.g., Sankarasubramanian et al, 2009), hydropower production management (e.g., Garcia-Morales and Dubus, 2007), and crop yield predic-tion (e.g., Hansen et al, 2006;Zinyengere et al, 2011). Due to the improvement of numerical models, prediction techniques, and computing resources, there is an increasing focus on sub-seasonal forecasts (e.g., Toth et al, 2007;Vitart et al, 2008;Brunet et al, 2010;Hudson et al, 2011bHudson et al, , 2013Robertson et al, 2014).…”
