Decadal variability analysis of extreme precipitation in Turkey and its relationship with teleconnection patterns
Abstract Natural disasters such as droughts and floods originate as a consequence of excessive high or low precipitation amount and/or frequency. Due to the temporal persistence of the latter, the disasters tend to cluster in time. Because global ocean–atmosphere teleconnection patterns with (multi‐...
