What is the tropopause and what does it do?
The tropopause is the boundary that demarcates the troposphere from the stratosphere, and is the part of the atmosphere where there occurs an abrupt change in the environmental lapse rate (ELR), from a positive rate in the troposphere to a negative rate in the stratosphere.
What best describes the tropopause?
The tropopause is the atmospheric boundary layer between the troposphere and the stratosphere, and is located by measuring the changes in temperature relative to increased altitude in the troposphere and in the stratosphere.
What is the importance of tropopause?
The water cycle also occurs in this layer of the atmosphere. The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.
Which is called the tropopause limit?
The tropopause is traditionally defined by meteorologists as the lowest level at which the rate of decrease of temperature with respect to height (normally about 6 K km−1 in the troposphere) decreases to 2 K km−1, and the average from this level to any level within the next 2 km does not exceed 2 K km−1.
How is tropopause important to us?
The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.
What is immediately above the tropopause?
The stratosphere is the layer of Earth’s atmosphere immediately above the troposphere; it extends from a lower boundary (the tropopause) whose altitude varies between about 8 and 16 km to an upper boundary (the stratopause) near 50 km.
What is located immediately above the tropopause?
The upper layers of the atmosphere include the stratosphere, immediately above the tropopause; the mesosphere above the stratopause and the thermosphere. The ozone layer that shields the Earth’s surface from lethal doses of ultraviolet radiation is located between 20 and 30 km within the stratosphere.
What is the approximate height and temperature of the tropopause?
The height for the tropopause is the tropopause is about 20 km (12 miles or 65,000 feet) above sea level. It’s temperature typically, drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet). 0.0.
Which feature is associated with the tropopause?
Tropopause jet-front systems are transient yet pervasive dynamic and thermodynamic features are found in the vicinity of the sloping midlatitude tropopause. These systems, also known as upper-level jet-front systems, are characterized by a local wind speed maximum (i.e., the jet core) along the tropopause surface.
