Formation and Types of Clouds in Esfahan, Iran

The diverse topography of Esfahan, Iran, ranging from the arid central plateau to the mountainous Zagros region, influences the formation of various cloud types. During the summer months, convective clouds, such as cumulus and cumulonimbus, dominate the skies. These clouds form due to the intense heating of the Earth’s surface, leading to the upward movement of warm, moist air. In the afternoons, these clouds can develop into thunderstorms, often bringing much-needed precipitation to the dry region.

During the winter, stable layers of stratus clouds cover large areas of Esfahan. These clouds form when a layer of warm air traps cooler, moist air below, preventing vertical convection. As a result, the moisture condenses into flat, gray cloud layers. Additionally, orographic clouds, such as lenticular clouds, can form when moist air is forced up over the Zagros Mountains. These clouds are often lens-shaped and can persist for extended periods, creating stunning visual displays.

Seasonal Distribution of Precipitation

Precipitation in Esfahan, Iran, exhibits a pronounced seasonal pattern. The city experiences a dry summer and a relatively wet winter. From June to September, precipitation is scarce, with average monthly totals below 1 mm. In contrast, precipitation increases significantly during the winter months, peaking in December and January when average monthly totals exceed 30 mm. This seasonal distribution is primarily influenced by the northward movement of the subtropical jet stream during winter, which brings moisture-laden air masses from the Mediterranean Sea to Esfahan.
