Climate Influences on Rainfall:

Sanandaj’s rainfall patterns are heavily influenced by its geographical location and topography. The city lies within the Zagros Mountains, which create a rain shadow effect on the west side of the range. This effect causes the western slopes of the mountains to receive significantly more rainfall than the eastern slopes.

Causes of Snowfall in Sanandaj

Snowfall in Sanandaj, Iran, is caused by a combination of factors, including its geographic location, topography, and climate. The city is situated in the Zagros Mountains, which create a barrier to the flow of warm air from the Persian Gulf. This, combined with the city’s high elevation of over 5,000 feet, leads to cold winters with frequent snowfall. Additionally, the city’s location in the path of moist air masses moving in from the Mediterranean Sea also contributes to snowfall, as these air masses release precipitation when they encounter the colder temperatures and higher elevations of Sanandaj.

Snowfall in Sanandaj can have a significant impact on the city and its residents. Heavy snow can block roads, making travel difficult and dangerous. The weight of snow can also cause damage to buildings and infrastructure, leading to costly repairs.

Seasonal Variation of Humidity

Humidity in Sanandaj exhibits significant seasonal variations, influenced by the city’s geographical location and climate. During the warm and dry summer months, relative humidity levels typically range from 20 to 35%.

However, as autumn approaches, humidity levels gradually increase, reaching their peak during winter. From December to February, Sanandaj experiences high humidity, with relative humidity values often exceeding 70%. This is primarily due to the influx of humid air from the Caspian Sea and the surrounding mountains, which trap moisture within the city’s valleys.
