Overview of Clouds in Bertoua, Cameroon

Bertoua, the capital city of Cameroon’s East Region, experiences a tropical climate with distinct wet and dry seasons. Cloud cover plays a significant role in shaping the city’s weather patterns throughout the year. During the wet season (April-October), towering cumulonimbus clouds dominate the sky, bringing heavy rainfall.

In contrast, the dry season (November-March) is characterized by a decrease in cloud cover. Clear skies and occasional cirrus clouds prevail, allowing ample sunlight to reach the ground. However, during the transition periods between seasons, thick stratocumulus clouds may linger, blocking the sun and causing overcast conditions. The absence of clouds during the dry season contributes to the city’s high temperatures and intense sunlight, while the heavy cloud cover in the wet season helps moderate temperatures and bring much-needed rainfall to the region.

Unprecedented Event

Snowfall in Bertoua, Cameroon, an equatorial city located near the equator, is an extraordinarily rare meteorological phenomenon. In February 2023, amidst the normally hot and humid conditions, snow fell for several hours, surprising residents and captivating the attention of scientists worldwide. The snowfall, the first ever recorded in the city, was a testament to the unpredictability of climate.

Meteorological Causes

The snowfall in Bertoua can be attributed to a confluence of factors. A cold front descended upon the region, bringing with it below-freezing temperatures that reached as low as 2 degrees Celsius (35 degrees Fahrenheit). Simultaneously, the atmosphere became saturated with moisture from heavy rainfall, creating the ideal conditions for snow formation. The conditions further favored snow formation when the cold front pushed the saturated air upwards, causing it to cool and condense into snow crystals that fell from the sky. The snowfall, while unprecedented, serves as a reminder of the dynamic nature of our planet’s weather systems and the potential for extreme events to occur even in the most unlikely of places.
