The stratosphere, situated between the troposphere and the mesosphere, is characterized by a temperature inversion, meaning temperatures increase with altitude. This region, home to the ozone layer, plays a critical role in absorbing harmful ultraviolet radiation from the sun. A notable example of stratospheric phenomena is the formation of nacreous clouds, also known as polar stratospheric clouds, which are composed of ice crystals and nitric acid and are often observed in polar regions during winter.
This atmospheric layer’s stability and unique temperature profile are crucial for several reasons. The ozone layer’s presence within the stratosphere protects life on Earth from harmful solar radiation, making it essential for the existence of diverse ecosystems. Furthermore, the stable conditions within the stratosphere influence long-range weather patterns and the global circulation of air masses. Scientific exploration of this region, commencing with early balloon ascents in the early 20th century, continues to yield valuable insights into atmospheric chemistry, dynamics, and the impact of human activities.
