Monthly total precipitation data are employed for 107 stations (1963-2002). Precipitation regime shape (seasonality) and magnitude (size) are classified using a novel multivariate methodology. Six shape and five magnitude classes are identified, which exhibit clear spatial structure. A composite (shape and magnitude) regime classification reveals dominant controls on spatial variability of precipitation. Intra-annual timing and magnitude of precipitation is highly variable due to seasonal shifts in Polar and sub-Tropical zones and physiographic factors. Nonetheless, the classification methodology is shown to be a powerful tool that identifies physically-interpretable precipitation regions: (1) coastal regimes for Marmara, coastal Aegean, Mediterranean and Black Sea; (2) transitional regimes in continental Aegean and Southeast Anatolia; and (3) inland regimes across Central and Eastern Anatolia. This research has practical implications for understanding water resources, which are under ever growing pressure in Turkey.eninfo:eu-repo/semantics/openAccessprecipitation climatologyrainfallregimesregionalizationclassificationTurkeyArticle55223424910.1080/02626660903546142Q2WOS:0002780130000082-s2.0-78649745188Q1
