What is tropopause?

tropopause is a thin layer of the Earth's atmosphere that separates the lower troposphere and higher stratosphere. There are about 36,000 feet (1,100 meters) above the sea level and increases to 58,000 feet (1,700 m) around the equator. Tropopause is remarkable as the ceiling under the fact that most of the earthly weather occurs. Between each layer is the boundary, named using the prefix of the bottom layer and the extension -pauze. These layers and boundaries are mainly defined according to the properties of temperature, pressure and density, as well as a phenomenon known as the speed of temperature delay. In the troposphere, the temperature is reduced by 3 ° F for every 1,000 feet at an altitude (6.5 ° C per 1,000 m). Thetropopause indicates the level that this trend switches. As soon as the stratosphere, inverts and the temperature of the delay begin to increase with altitude.

Air ride is affected by tropopause because the jet drive is more efficient with colderCH temperatures. The speed of the troposphere delay provides a reliable basis for calculating fuel consumption and pilots are to fly just below the tropopause to maximize power. Most of the water vapor is held closer to the ground, so there are several clouds near tropopause and generally low turbulence, unlike below below in the troposphere. That is why it is almost always sunny when a commercial aircraft reach a height.

From the ground, the tropopauz can sometimes be observed by visually storm clouds that flatten into the shape of an anvil. This happens when the warm air from the storm pushes up until it reaches the peakutroposphere, where it is no longer less thick than the air around it. Then it spreads outwards.

Although tropopause acts as a relatively consistent ceiling for troposphere, it is not impregnable. For example, tropical storms that get through Earth can sometimes break into the stratosphere. When this happens, water vapor transmitted by storm clouds can freeze and be transmitted thousands of kilometersby air currents. Some scientists theorizing this phenomenon is a natural contributing factor to the greenhouse effect, because water vapor, which is high up to capture heat near the ground.
