The consistently high atmospheric moisture content characterizing this equatorial region is a defining feature of its climate. This abundance of water vapor in the air results from a combination of factors, including intense solar radiation, extensive evapotranspiration from the dense vegetation, and significant precipitation. For example, average relative levels frequently exceed 80% throughout the year.
This pervasive atmospheric condition is fundamental to the rainforest’s biodiversity and ecological function. It supports the growth of a vast array of plant life, which in turn sustains a complex food web. The abundant moisture also plays a crucial role in regulating regional weather patterns and influencing global climate through processes such as cloud formation and carbon sequestration. Historically, indigenous communities have adapted their lifestyles to this environment, developing agricultural practices and building materials suited to the moist conditions.
