Cirrus clouds, composed of ice crystals, often adorn the sky, providing stunning visual displays. They are typically thin and wispy, allowing sunlight to pass through, resulting in minimal impact on precipitation. Altocumulus clouds, characterized by their rounded shapes and gray or white appearance, are also prevalent. These clouds often indicate stable atmospheric conditions and generally do not produce precipitation, unless combined with other cloud types. Altostratus clouds, featuring a uniform gray or blue-gray layer covering the sky, may bring light drizzle or snow, depending on the temperature and moisture content of the atmosphere.

Low-Level Clouds

Low-level clouds in Shahriar, Iran, have a significant influence on weather conditions. Stratus clouds, with their uniform gray appearance and base close to the ground, often bring overcast skies and can persist for extended periods. They may produce drizzle or light rain, but heavier precipitation is uncommon. Cumulus clouds, characterized by their puffy, cotton-like appearance, are associated with fair weather and typically do not produce rain. However, when these clouds develop vertically, they can transition into cumulonimbus clouds, leading to precipitation, lightning, and even thunderstorms. Nimbostratus clouds, which have a dark, layered appearance, can bring prolonged periods of precipitation, often in the form of drizzle, rain, or snow.

Annual Precipitation and Distribution

Shahriar, located in Iran’s Alborz province, experiences an average annual precipitation of around 300 mm (11.8 inches). However, this precipitation is not evenly distributed throughout the year. The city receives most of its rainfall during the winter and spring months, from November to April. During these months, frequent westerly and northerly winds bring moist air from the Caspian Sea and produce precipitation in the form of rain or snow.

Seasonal Variations and Climate Impacts

In the summer, precipitation is scarce in Shahriar. The city experiences hot and dry conditions with minimal rainfall. Precipitation levels begin to increase again in the fall, as cooler temperatures and the arrival of the Mediterranean cyclones start to influence the region.
