Seasonal Distribution of Precipitation

The distribution of precipitation in Hamadan varies significantly throughout the year. During the winter months, the city experiences its highest rainfall, with average monthly precipitation exceeding 60 millimeters (2.4 inches) in December and January. This precipitation often falls as snow due to the city’s high elevation. In contrast, the summer months are extremely dry, with average monthly precipitation of less than 2 millimeters (0.08 inches).

Factors Influencing Rainfall

The precipitation patterns in Hamadan are influenced by several factors. The city’s location on the leeward side of the Zagros Mountains plays a significant role. These mountains intercept much of the moisture-carrying clouds from the Mediterranean, resulting in a rain shadow effect and contributing to the city’s aridity. Additionally, the Siberian High, a large anticyclone that forms over Siberia during winter, often extends its influence over Hamadan, leading to cold, dry conditions.

Variation and Patterns of Humidity in Hamadan, Iran

Hamadan, located in northwestern Iran, experiences significant variations in humidity throughout the year. The city has a dry continental climate with hot, dry summers and cold, snowy winters. Humidity levels fluctuate widely between seasons, ranging from very dry during the summer months to relatively humid during the autumn and winter. During the summer, humidity levels typically dip below 20%, resulting in a dry and arid atmosphere. This dryness is exacerbated by the city’s high altitude (1,850 meters) and the prevailing wind patterns from the dry interior of Iran.

In contrast, humidity levels rise during the autumn and winter months. As temperatures drop and precipitation increases, the air becomes more saturated with moisture. Humidity levels can reach up to 70% or higher during these months, creating a damp and misty atmosphere. This increased humidity is influenced by the influx of moisture from the Mediterranean Sea and by the condensation of atmospheric water vapor on cold surfaces. The high humidity can lead to fog and mist formation, especially in the mornings and evenings.

Wind Patterns in Hamadan, Iran

Hamadan, located in western Iran, experiences a continental climate with distinct seasonal variations. The prevailing wind direction in Hamadan is from the northwest during the winter months, as the Siberian High extends over much of Asia.

During the summer months, the wind direction shifts to the southwest, as the North Indian Ocean High influences weather patterns in the region. These warmer, humid winds often bring precipitation, particularly during the thunderstorm season.

Impacts of Wind on the Environment and Human Activities

The strong winds in Hamadan have a significant impact on the local environment and human activities. The prevailing northwesterly winds in winter can cause soil erosion, leading to the formation of dust storms. These dust storms can reduce visibility and affect the health of residents.
