Temporal and spatial patterns of precipitation variability for annual, wet, and dry seasons in Turkey
Abstract In the present study, annual, wet and dry seasons precipitation records for the period 1961–2008 from 271 stations in Turkey were analysed using the rotated empirical orthogonal function (REOF), the Mann‐Kendall trend test and the continuous wavelet transform (WT) method. Additionally, rela...
