Cloud Cover

Mekele, located in northern Ethiopia, experiences varying cloud cover throughout the year. During the dry season, from October to May, skies are typically clear or partly cloudy. This is due to the prevailing northeasterly trade winds that bring dry air from the Sahara desert. As a result, cloud cover is minimal during these months.

In contrast, the wet season, which runs from June to September, witnesses a significant increase in cloud cover. The influx of moist air from the Indian Ocean leads to the formation of clouds, resulting in frequent showers and thunderstorms. During this period, skies are often overcast or partly cloudy, providing relief from the intense sunlight.

Cloud Types

The types of clouds observed in Mekele vary depending on the season and prevailing weather conditions. During the dry season, cirrus and cumulus clouds are common. Cirrus clouds are thin, wispy clouds that are composed of ice crystals and appear high in the atmosphere. Cumulus clouds, on the other hand, are puffy, cotton-like clouds that are associated with fair weather.

During the wet season, cumulonimbus clouds become prominent. These are tall, anvil-shaped clouds that can produce heavy rainfall and thunderstorms. In addition, stratus and nimbostratus clouds are also observed during this period, bringing prolonged periods of drizzle or light rain.

Precipitation Patterns

Mekele, a city located in northern Ethiopia, experiences rainfall primarily during the summer months. The dominant precipitation mechanism is the Intertropical Convergence Zone (ITCZ), a belt of low pressure that brings moist air from the Atlantic Ocean. The peak wet season occurs from June to September, with an average monthly rainfall of over 100 mm. During this period, rainfall is often intense and can cause flooding in the city’s low-lying areas.

Annual Variability and Trends

The annual precipitation in Mekele varies considerably from year to year. Droughts and floods are common occurrences. Severe droughts, caused by shifts in weather patterns or climate change, can lead to water shortages and crop failures. Floods, on the other hand, occur when intense rainfall overwhelms the city’s drainage system. In recent years, Mekele has witnessed an increase in extreme precipitation events, such as heavy downpours and flash floods. These events have raised concerns about the resilience of the city’s infrastructure and the safety of its residents.

Rainfall Variability
