Historical Context

Snowfall is an extremely rare occurrence in the Democratic Republic of Congo, including the city of Kolwezi. Located near the equator, Kolwezi experiences a tropical climate with consistently high temperatures and abundant rainfall. Historically, snowfall has been virtually non-existent in the region. However, a remarkable event occurred on January 28, 1961, when a thin layer of snow fell over Kolwezi and the surrounding areas. This unusual weather phenomenon was attributed to an exceptionally cold air mass that moved across the continent, resulting in an overnight drop in temperature.

Scientific Explanations

The 1961 snowfall event in Kolwezi is an intriguing meteorological occurrence that has been studied by scientists. Atmospheric models and weather patterns have been analyzed to understand the factors that contributed to this rare event. One explanation suggests that a cold front from the south interacted with warm, moist air from the Congo Basin, creating a localized area of extreme temperature inversion. The cold front pushed the warm air upward, causing it to cool and condense into snow. Another theory points to the influence of a high-altitude jet stream, which brought cold, dry air from the South Atlantic Ocean over the region. As this airmass descended, it encountered moisture in the atmosphere, leading to snowfall.
