Mesopauza

Mesopause is a region of the Earth's atmosphere located at an altitude of approximately 85 kilometers (53 miles) above the Earth's surface. It is the boundary between the mesosphere and the thermosphere. The mesopause is characterized by a temperature minimum, typically around -90 degrees Celsius (-130 degrees Fahrenheit), which is the coldest naturally occurring temperature in the Earth's atmosphere. This temperature minimum is due to the decrease in solar radiation at this altitude, as the atmosphere becomes thinner and less able to absorb and retain heat.

The mesopause is also the region where the majority of meteors burn up upon entering the Earth's atmosphere. These meteors, known as meteoroids, are small particles of dust and rock that enter the atmosphere at high speeds. As they pass through the mesopause, they are heated by friction with the air molecules, causing them to vaporize and create the streaks of light known as meteors.

The mesopause is an important region for studying the Earth's atmosphere and its interactions with space. It is also a region of interest for space exploration, as it is the boundary between the Earth's atmosphere and the vacuum of space. The mesopause is a dynamic region, with temperatures and winds that can vary significantly over short periods of time. Understanding the mesopause and its dynamics is crucial for a variety of applications, including weather forecasting, climate modeling, and space weather prediction.
