ABSTRACTThis study uses a climatological approach that is based on calculations of different characteristics of rain-spells by making use of daily precipitation data recorded at 69 principal climatological and synoptic meteorological stations of the Turkish State Meteorological Service (TSMS) network of the Republic of Turkey during the period 1970 to 2011. A rain-spell is defined as a series of consecutive days with a measured daily rainfall equal or higher than 1.0 mm. Each rain-spell is preceded and followed by at least one dry day. Rain spells are characterized by their average rain-spell yield (RSY in mm), average rain-spell intensity (RSI in mm/day) and the average rain-spell duration (RSD in hrs.). Furthermore, the average annual number of rain-spells (NRS) and the longest rain-spell duration (LRSD in days) with a return period of at least once in a year were calculated. All calculated rain-spell variables and parameters were mapped, and their magnitude and spatial distribution patterns were synthesised by taking into account several climate classifications including the Köppen-Geiger climate classification as a macro climate controls, the Thornthwaite’s climate types corresponding to the Moisture Index (Im), two different aridity indices, and statistical classifications of the precipitation regime and climate types dominated over different geographical regions of Turkey. The spatial variability of these rain-spell characteristics and parameters reveal a considerable climatic diversity in Turkey as expected based on the well-known climate and rainfall regime types performed by the previous peer-reviewed studies such as, Türkes (1998, 1999, 2003), Iyigun et al. (2013), Reiser and Kutiel (2009, 2010a, 2010b), Sahin and Cigizoglu (2012), and Türkes and Tatli (2011), etc.
