Determine the Beginning and End of the Thermal Seasons with the Scrutiny Approach of the Natural Seasons (Case Study: Different Areas of Kerman Province)

Due to the climate variation in different regions of the province of Kerman, and the importance of temperature in climatic hazards such as frostbite, late spring periods and heat stress, the extraction of temperature periods is necessary with a Scrutinyapproach to the natural seasons of the province. For this purpose, after providing daily databases, for the preparation of 73 rows and 12 columns per quadrant matrix, the average temperature data of the synoptic stations of Lalehzar, Baft, Shahrbabak, Kerman, Sirjan, Zarand, Anar, Rafsanjan, Bam, Jiroft, Kahnouj, and Shahdad were used. Then, using statistical analyzes and manual method, the beginning and the end of temperature periods in different regions of Kerman province were determined and the temperature seasons of these areas were extracted. The results of this study showed that with the exception of the Lalehzar area, which has three seasons of temperature corresponding to the natural seasons of winter, spring and autumn, the remaining regions of Kerman province have four separate seasons. However, it is different from time to time, the beginning and the end of the seasons in different regions of Kerman province. The longest natural summers are Shahdad and Kahnouj and the longest natural winters are Laleh Zar. In addition to the potential for temperature variation in different areas of the province, occurrence of climatic hazards, such as late pomegranate, can be detected.
