Types of Clouds

Omdurman experiences various cloud types throughout the year. During the dry season (November to April), the skies are typically clear with occasional cirrus clouds. Cirrus clouds are thin, wispy clouds that appear high in the atmosphere and are composed of ice crystals. As the rainy season approaches (May to October), cumulus clouds become more prevalent. Cumulus clouds are puffy clouds that often indicate fair weather. During heavy rainfall, nimbostratus clouds may form, which are thick, dark clouds that produce widespread precipitation.

Cloud Cover and Solar Radiation

The extent of cloud cover in Omdurman significantly impacts the amount of solar radiation reaching the ground. During the dry season, when cloud cover is minimal, the city receives high levels of solar radiation, resulting in hot and sunny days. In contrast, during the rainy season, cloud cover increases, leading to reduced solar radiation and cooler temperatures. The average cloud cover in Omdurman varies throughout the year, with the highest percentage occurring during the rainy season.

Annual Precipitation

Omdurman, Sudan experiences an annual precipitation of approximately 150 millimeters (6 inches). The majority of this precipitation occurs during the rainy season, which lasts from June to October. During these months, Omdurman receives on average 30-40 millimeters of rainfall per month. The remaining six months of the year are generally dry, with little to no precipitation.

Seasonal Distribution

The precipitation in Omdurman is highly seasonal, with the majority of the rain falling during the summer months. The months from November to May are typically very dry, with less than 10 millimeters of precipitation per month. The rainy season begins in June and peaks in August, with an average of 50 millimeters of rainfall per month. September and October also receive significant rainfall, with an average of 40 millimeters per month. By November, the rainy season ends, and the dry season begins.

Distribution and Variability

Omdurman, located in northern Sudan, experiences highly variable rainfall patterns. The city lies within the semi-arid Sahel region, receiving an average of just 154 millimeters (6.1 inches) of rain annually. Rainfall is concentrated during the summer months, typically between June and October, when the Intertropical Convergence Zone (ITCZ) shifts northward. During this period, heavy storms can produce significant rainfall, accounting for the majority of Omdurman’s annual precipitation.

Rainfall variability in Omdurman is influenced by several factors, including El Niño-Southern Oscillation (ENSO) events. During El Niño years, which are characterized by warmer-than-average ocean temperatures in the Pacific Ocean, rainfall tends to be below average in the Sahel region, including Omdurman. Conversely, during La Niña years, which are associated with cooler-than-average ocean temperatures in the Pacific, rainfall is typically higher. Additionally, the Indian Ocean Dipole (IOD) also plays a role in influencing rainfall variability in Omdurman, with positive IOD events coinciding with above-average rainfall and negative IOD events associated with below-average rainfall.

Historical Rarity of Snowfall in Omdurman, Sudan

Snowfall is an extremely rare occurrence in Omdurman, Sudan, with no recorded instances of significant snowfall in the city’s history. The average temperature in Omdurman ranges from 25 to 40 degrees Celsius (77 to 104 degrees Fahrenheit) throughout the year, making the conditions unsuitable for snowfall. The lack of snowfall can be attributed to the city’s location in a semi-arid region with consistent high temperatures, low humidity, and a lack of moisture necessary for snow formation.

Climatic Factors Contributing to Snowfall Rarity

The climatic factors that contribute to the rarity of snowfall in Omdurman include the presence of the Sahara Desert to the north, the Red Sea to the east, and the Ethiopian Highlands to the south. The Sahara Desert’s dry and hot air masses prevent cold fronts from reaching Omdurman, while the Red Sea’s warm waters further increase temperatures. Additionally, the Ethiopian Highlands act as a barrier, blocking moisture-carrying winds from the Indian Ocean from reaching the city. These combined factors create a stable atmospheric pattern that inhibits the development of snow-producing conditions in Omdurman.

Sunrise and Sunset Times

In Omdurman, Sudan, the sun rises and sets at different times throughout the year due to the Earth’s tilt and its orbit around the sun. During the summer solstice in June, the sun rises at approximately 5:45 AM and sets at around 6:30 PM. During the winter solstice in December, the sun rises at around 7:00 AM and sets at 5:30 PM. These times may vary slightly depending on the specific location within Omdurman.

The new moon occurs when the moon is not visible from Earth, while the full moon occurs when the entire face of the moon is illuminated. The phases of the moon can be observed with the naked eye or through telescopes.

Humidity Levels in Omdurman

Located in central Sudan, Omdurman experiences high humidity levels throughout the year. The city has a tropical savanna climate, characterized by hot, dry summers and shorter, less severe winters. During the summer months, from April to October, humidity typically hovers between 40% and 80%, peaking in August and September when average relative humidity exceeds 70%. The high humidity during this period is primarily driven by the moist air brought in by the southwesterly monsoon winds.

Seasonal Variations

Humidity levels in Omdurman exhibit distinct seasonal variations. During the winter months, from November to March, humidity drops significantly due to the influence of dry continental air masses. Relative humidity typically ranges between 20% and 50% during this period, providing a respite from the oppressive humidity experienced during the summer. However, during the transition months of April and November, humidity levels can fluctuate abruptly as the monsoon winds shift and the dry continental air masses clash.

Wind Speed and Direction

Omdurman, Sudan, experiences a distinct pattern of wind speed and direction throughout the year. During the dry season (November to May), the prevailing wind is the northeasterly trade wind, which blows from the Sahara Desert and brings hot, dry air. These winds are typically strong, with average speeds ranging from 15 to 25 kilometers per hour (9 to 16 miles per hour).

During the rainy season (June to October), the dominant wind direction shifts to the southwest. These winds are associated with the Intertropical Convergence Zone (ITCZ), a low-pressure area that brings moisture-laden air from the Gulf of Guinea. Wind speeds during this period are generally lighter, averaging around 10 to 15 kilometers per hour (6 to 9 miles per hour).

Wind Impact

The strong winds in Omdurman have a significant impact on the city’s environment and daily life. The dry, dusty northeasterly winds can create a thick haze, reducing visibility and affecting air quality. During the rainy season, the southwesterly winds bring much-needed rainfall, but can also lead to flooding and damage to infrastructure.

The wind also plays a vital role in the city’s energy production. Omdurman has several wind farms that harness the abundant wind resources to generate electricity. The wind turbines are strategically placed to capture the strong, consistent winds throughout the year, providing a sustainable source of renewable energy.
