Effective global climate classifications are mostly based on complex evaluation of climate records, sometimes supplemented by phytological information. Owing to the insufficient data bases, including the number of climate stations and the length of time series available for the different climatic elements in different areas, these climate classifications have varying degrees of weakness. Moreover, classifications impose sharply drawn borders on natural climatic transition zones. In addition, the climate types often credibly describe only the centre of the region, and the reliability of this typification decreases with increasing distance from this centre. Furthermore, effective climate classifications are static systems that do not consider climatic fluctuations (Buckle, 1996).
