Abstract

There is a growing evidence that the climate change has already had significant impacts on the world’s physical, biological, and human systems, and it is expected that these impacts will become more severe in the near future. Alterations in the weather patterns and the existence of extreme events can be considered as important indicators of this change. The validity of this reality can be judged by analyzing climate data thoroughly. In this study, for determining the climate zones of Turkey, temperature measures obtained from the Turkish State Meteorological Service stations in the period 1950–2006 are examined by using two center-based clustering methods, namely k-means and fuzzy k-means. The clusters obtained from these methods are compared using objective criteria. They are also evaluated subjectively by the domain experts.
