How do high elevations affect temperatures in Eastern Africa?

In Eastern Africa, elevation is a primary factor in moderating temperatures, as the region generally experiences a decrease in temperature as altitude increases. While lower-lying areas and inland troughs often feature hot, dry climates, higher elevations experience significantly cooler conditions, often approaching those of temperate zones.1234

This altitudinal modification creates distinct climatic zones within the region. For instance, while lowland areas may maintain high average temperatures, highland regions exhibit much cooler annual averages. On the highest peaks, such as Kilimanjaro, Mount Kenya, and the Ruwenzori Range, temperatures can drop to the point where frost, snow, and glaciation occur. At the summit of Mount Kenya, temperatures rarely rise above the freezing point, and precipitation at the highest altitudes frequently falls as snow. Consequently, these mountains possess their own unique climatic zones that vary progressively with altitude, distinct from the surrounding tropical lowlands.253146
