Determination of Climatic Type of the Kuhdasht Synoptic Meteorological Station of Lorestan Province, Iran

Abstract

The climatic behavior of each area is predictable using the long-term data and applying
the appropriate method of climatic classification for the area under study. The basic objective
of the present study is to determine the climatic type of the Kuhdasht synoptic meteorological
station and to achieve the desirable result , the following steps have been followed. At the
first stage, we collected the total annual rainfall and average annual temperature data for the
Kuhdasht meteorological station from year 1998 up to year 2014 for the duration of 17
years. At the second step using the De Martonne method drought coefficient for each listed
years has been calculated. At last ,drought coefficient obtained for 17 years is being averaged
which comes to 14.40. As per De Martonne classification table, climatic type of the Kuhdasht
synoptic meteorological station falls into the category of Semi-dry climate. This means that
the Kuhdasht station experiences a dry season followed by rainy season. The dry season
would be at least, more than three months. In the case of Kuhdasht station, it observes dry
season or low rainfall season for longer period than its rainy season and often observes the
activities associated with an air mass in range of our study station during every year
