Mesopausa
Sign in to saveThe mesopause is the point of minimum temperature at the boundary between the mesosphere and the thermosphere atmospheric regions. Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, the mesosphere is the coldest region on Earth with temperatures as low as -100 °C (-148 °F or 173 K). The altitude of the mesopause for many years was assumed to be at around 85 km (53 mi), but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact there are two mesopauses - one at about 85 km and a stronger on

La mesopausa è il terzo livello dell'atmosfera che delimita due strati: la mesosfera e la termosfera. La temperatura della mesopausa è la più fredda che si incontra nell'atmosfera (circa -80 °C). Viene identificata ad un'altitudine di circa 85 km. Al confine fra mesopausa e termosfera hanno luogo le aurore polari.
