Zoning of Iran Temperature using modern method based on SVD and fuzzy clustering

Climate is one of the most important environmental factors that impact human life and activities. Therefore, it is important to know about climate zones for planning and spatial development of different reigns. The main purpose of this research is zoning the temperature of Iran using fuzzy clustering. Data about mean of daily dry temperature, maximum temperature, minimum temperature, dew point temperature and wet temperature of 63 synoptic stations in Iran were collected from meteorology office during 1989 to 2013. Data were reduced in MATLAB software using SVD method and clustered using fuzzy clustering. Results indicate 6 temperature clusters in Iran. Temperature zoning of Iran is affected by the Caspian Sea, Persian Gulf, Oman Sea, Alborz and Zagros mountain ridges, and internal areas of Iran.
