Climate classification of Kermanshah province using cluster analysis and climatic models

چکیده مقاله

Climate is a compendium and complicated condition of a region atmosphere that change with latitude and other geographic factors obviously. There is no formula and basic method to classify the climate of the world which is approved by all of the scientists, Therefore classification has done base on different goals. The present study has been conducted for climate zonation of Kermanshah province in 1:50000 scale using Embereger & revised De Martonne methods. The goals of this research are climate zonation of Kermanshah province based on accurate and proper statistical data and information; province climate scheme using climate methods based on natural basins; utilizing and introducing a new approach to statistical analysis of data and information in natural regions; comparing the outputs of statistical models with natural characteristics of regions and comparing the climate types of Kermanshah Province producing by the methods were used in this research. Three climate homogenous regions were segregated using statistical of stations and clustering. Borders of basins for stations of each homogenous region selected as a border divider of homogenous regions; different statistical analysis was done and gradient of temperature and precipitation was calculated for every homogenous region separately, then climate zonation of each region was done using Embereger and revised De Martonne methods. Results of this study revealed cold humid climate and semi-arid temperate climate with 18.7% and 16.2% of Kermanshah province area have highest relative abundance and warm temperate ultra arid climate covered only 0.1% of this. A general pluralization can be said Kermanshah province has various climates, naturally that there are 12 and 8 types of climate in Kermanshah province using revised De Martonne and Embereger respectively. Existence of very cold humid type I till warm ultra arid temperate has a special importance and these several of climate can increase the production potential of agriculture, natural resources and tourism in Kermanshah province
