Considering that the Sarbandan village is located in the east of Damavand city, its climate is similar to the climate of Damavand city and neighboring villages. As a result, considering the available information, we study the climatic features of this village in this article.

Sarbandan village is a mountainous area on the southern slopes of the Alborz mountains. It has a cool, dry mountain climate with mild and gentle summers and very cold winters. The rainfall in this village is relatively high due to its mountainousness and its location on the southern slopes of Alborz. How the wind blows with the geographic location and the overall face of the complications and tides and the heights are closely related. The flow of northwest and northwest from the beginning of October to mid-spring continues to cause rain and cold weather in the region, and the warm and dry air flows from the middle of the spring to the end of the summer, from the desert region of Iran The area is flowing, however, the presence of dome-shaped mountains and large gardens and greenery somewhat reduces the heat, but it still affects. The presence of large and small valleys, permanent streams in days and nights, the flow of Nisa Mountain to the valley, valley to the mountain is well felt. The general wind is in the western wind region. The three major factors of altitude, desert plain and rainy winds have a major role in determining the climate of Sarbandan village. The village is affected by cold seasons from the northern, northwest, and southern systems, which caused the weather to be cold and dry in the winter and in the summer due to the advent of hot and dry weather with airborne dust. The existence of these two weather flows has also caused air modification in all seasons.
In the study area, the average temperature is at least 2.4 ° C and the average temperature is 24.3 ° C in the year, and the difference between the average minimum temperature and the maximum temperature in the year is 1/20 ° C. The minimum absolute temperature is -26.5 ° C and the absolute maximum is 48.5 ° C in July, and the difference between the maximum and minimum absolute values is 75 ° C per month.
Combining climatic factors such as temperature, relative humidity and air flow affect humans and is associated with physical comfort. According to the researchers’ research over the years and a preliminary study conducted by residents of different areas throughout the year, it is estimated that the temperature of 24 degrees Celsius and relative humidity is about 50 percent in summer for 98 percent of the subjects, The winter is favorable for 97% of the temperature of 21 ° C and relative humidity is 50%. In the study area, the highest humidity is in December and the lowest is in July.
The dominant air and wind masses:
You are the air desert in the winter, the Mediterranean from the west, the Arctic and the north pole from the northwest, and the polar sea from the northwest and in the summer, and the arrow from the desert of Iran or the Arabian desert. Also, the flow of massive air masses and wet and hot arrows in the summer from the northwest or southeast have been reported accidentally. The wind direction is dominant in the western and southeast of the year.
