Dictionary definition of stratosphere

The second layer of the Earth's atmosphere, lying above the troposphere and below the mesosphere.
"The stratosphere is characterized by a relative lack of weather and turbulence."

Detailed meaning of stratosphere

It extends from about 8 to 50 kilometers (5 to 31 miles) above the Earth's surface, and is characterized by a relatively stable temperature and low wind speeds. The stratosphere is divided into two main regions: the lower stratosphere and the upper stratosphere. The lower stratosphere is where the ozone layer is located, which protects the Earth from harmful ultraviolet radiation from the sun. The upper stratosphere is where jet streams and other high-altitude winds are found.

The stratosphere is not as well-mixed as the lower atmosphere, so it contains less water vapor, dust, and other particles. This means that air in the stratosphere is relatively clean and clear. It also contains a number of different gases such as ozone, nitrogen, oxygen and some trace gases which are important for the Earth's radiation balance. The stratosphere is also home to a number of high-altitude aircrafts and weather balloons that are used to study the upper atmosphere.

Example sentences containing stratosphere

1. The stratosphere is the second layer of the Earth's atmosphere.
2. Commercial airplanes typically fly in the lower stratosphere.
3. The ozone layer is located in the stratosphere.
4. The stratosphere is characterized by a decrease in temperature with increasing altitude.
5. Astronauts need to pass through the stratosphere to reach outer space.
6. The stratosphere plays a crucial role in regulating Earth's climate.

History and etymology of stratosphere

The noun 'stratosphere' has its etymological origins in Greek. It is formed from two Greek words: 'stratos,' meaning 'spread out' or 'layer,' and 'sphaira,' meaning 'sphere' or 'ball.' In atmospheric science, the 'stratosphere' refers to the second layer of the Earth's atmosphere, lying above the troposphere and below the mesosphere. The term 'stratosphere' emphasizes its position as a distinct layer or spread-out region within the Earth's atmosphere. This region is characterized by its unique properties, including the presence of the ozone layer, which plays a crucial role in absorbing and blocking harmful ultraviolet radiation from the sun. 'Stratosphere' reflects its Greek roots in the concept of a layered or spread-out sphere, distinguishing it from other atmospheric layers.
