The majority of the precipitation falls during the winter months, particularly between December and March, when the region is influenced by moist air masses from the Mediterranean Sea. During this period, light to moderate rainfall is common, occasionally accompanied by thunderstorms.

In contrast, the summer months (June to September) are generally dry, with little to no precipitation. This dryness is due to the influence of the subtropical high-pressure system, which brings clear skies and low humidity to the region.

Average Rainfall and Seasonal Patterns:

Khomeyni Shahr experiences a semi-arid climate with an average annual rainfall of approximately 250 millimeters. The precipitation is highly seasonal, with most rain occurring during the winter months from November to March. During this period, rainfall is often associated with low-pressure systems originating from the Mediterranean Sea. In contrast, summers are typically dry, with minimal rainfall.

Spatial Distribution and Impacts:

Rainfall in Khomeyni Shahr is not evenly distributed. The city is situated on the slopes of the Zagros Mountains, leading to variations in precipitation based on altitude. Higher elevations tend to receive more rainfall due to orographic effects, which force moist air to rise and condense as it encounters the mountain range. This results in increased rainfall on the western side of the city, while the eastern side experiences drier conditions. The variability in rainfall patterns can impact local agriculture, with farmers relying on irrigation systems to supplement rainfall during dry periods.

Phases of the Moon in Khomeyni Shahr, Iran

The Moon’s phases in Khomeyni Shahr, Iran, are determined by its position relative to the Sun and Earth. As the Moon orbits the Earth, its illuminated side faces either the Sun or the Earth. When the Moon is between the Sun and Earth, its dark side faces Earth, resulting in a new moon. As the Moon continues to orbit, its illuminated side gradually becomes visible to Earth, leading to a waxing crescent, first quarter, waxing gibbous, and finally a full moon when the entire illuminated side is facing Earth. After the full moon, the illuminated side gradually diminishes, resulting in a waning gibbous, third quarter, waning crescent, and finally a new moon again. The cycle of Moon phases takes approximately 29.5 days to complete.

Moonrise and Moonset in Khomeyni Shahr, Iran

The time of Moonrise and Moonset in Khomeyni Shahr, Iran, varies depending on the day and time of year. The Moon rises in the east and sets in the west, just like the Sun. However, the exact time of Moonrise and Moonset changes daily due to the Moon’s orbit around Earth and the Earth’s rotation. Additionally, the Moon’s altitude in the sky varies throughout the night, reaching its highest point at moonrise and gradually descending until moonset. The information on precise Moonrise and Moonset times for a specific date and location can be obtained from astronomical tables or online sources providing astronomical data.

Humidity Levels in Khomeyni Shahr, Iran

Khomeyni Shahr, a city situated in the Isfahan Province of Iran, experiences significant variations in humidity levels throughout the year. The city’s climate is influenced by its location in a semi-arid region, characterized by hot, dry summers and cold, dry winters. During the summer months, humidity levels typically remain low, often below 30%, contributing to the dry and arid conditions. However, as winter approaches, humidity levels gradually increase, reaching their peak during the months of December and January when they can exceed 60%.

The variation in humidity levels in Khomeyni Shahr can be attributed to several factors. During the summer months, the city’s proximity to the Zagros Mountains and the presence of the Namak Lake, which is located to the east of the city, contribute to the dry conditions. The mountains act as a barrier, preventing moisture-laden air from reaching the city from the Caspian Sea, while the Namak Lake, a vast salt lake, absorbs any remaining moisture from the air. In contrast, during the winter months, as the temperature drops and precipitation increases, the relative humidity rises. The city receives more rainfall during the winter months, which, combined with the lower temperatures, leads to higher humidity levels.

Wind Patterns

Khomeyni Shahr, Iran, experiences distinct wind patterns throughout the year. In the winter months, from December to February, the predominant wind direction is from the northwest, carrying cold air from the Caspian Sea and the Alborz Mountains.

Easterly and westerly winds prevail, often bringing clear and pleasant weather.

Impact on Climate

The wind patterns in Khomeyni Shahr have a significant impact on the local climate. The strong northwesterly winds in winter contribute to the city’s cold and dry winter conditions. The variable winds in spring and autumn help moderate temperatures and create a milder climate. Furthermore, the winds help disperse air pollution and maintain relatively good air quality throughout the year. However, during periods of strong winds, especially in the winter, dust and particulate matter can accumulate in the air, leading to reduced visibility and potential respiratory issues.
