Cloud Cover in Yaounde

Yaounde, the capital of Cameroon, experiences a tropical climate, characterized by its high temperatures and abundant rainfall. The city’s cloud cover is influenced by its location within the Intertropical Convergence Zone (ITCZ), which is a belt of low atmospheric pressure near the equator where the trade winds converge. This convergence creates a region of ascending air, leading to the formation of clouds and precipitation. As a result, Yaounde experiences frequent cloud cover, with an average of 70% to 80% cloudiness throughout the year.

During the dry season, which occurs from November to March, cloud cover is generally lower than during the wet season. However, even during the dry season, Yaounde experiences regular cloud formations, particularly in the early morning and late afternoon. The presence of clouds helps to moderate temperatures and reduce the intensity of the sun’s rays, creating a more pleasant and comfortable climate for outdoor activities. In addition, the cloud cover provides moisture to the surrounding vegetation, supporting the city’s lush green spaces and contributing to its vibrant biodiversity.

Annual Precipitation Pattern

Yaounde, the capital of Cameroon, experiences equatorial climate characterized by abundant year-round precipitation. The city’s annual precipitation averages around 1,700 millimeters (67 inches), making it one of the wettest cities in Cameroon. The distribution of rainfall throughout the year is relatively consistent, with two distinct rainy seasons and two shorter dry seasons.

The first rainy season occurs from March to October, peaking in August. During this period, heavy rainfall is common, with some days receiving more than 100 millimeters (4 inches) of precipitation. The second rainy season, known as the “minor rainy season,” lasts from October to December. Although still receiving significant rainfall, this season is less intense than the first.

Influence on Natural Resources and Economy

The abundant precipitation in Yaounde plays a crucial role in shaping the city’s natural resources and economy. The city’s lush vegetation is a testament to the high rainfall, providing essential habitats for a diverse array of plant and animal species. The Sanaga River, which flows through Yaounde, also benefits from the heavy rainfall, ensuring a steady water supply for the city and surrounding areas.

In terms of the economy, precipitation has a positive impact on agriculture. Yaounde and its surrounding regions are major agricultural centers, producing a wide range of crops, including cocoa, coffee, and bananas. The reliable rainfall ensures consistent growth and high yields, supporting the livelihoods of farmers and contributing to the local economy.
