relationship between average temperature and thickness of troposphere

How does temperature change with altitude in the troposphere? Characterize between average tropospheric temperature and the thickness of the troposhere?. Brought to you by the National Earth Science Teachers Association Temperatures drop as you move upward through the troposphere. an average atmosphere with variations caused by weather, latitude, The tropopause is the boundary between the troposphere (below) and the stratosphere (above). The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains approximately 75% of the atmosphere's mass and 99% of the total mass of water vapor and aerosols. The average height of the troposphere is 18 km (11 mi; 59, ft) in the The tropopause is an inversion layer, where the air temperature ceases to.

Measuring the temperature change with height through the troposphere and the stratosphere identifies the location of the tropopause.

In the troposphere, temperature decreases with altitude. In the stratosphere, however, the temperature remains constant for a while and then increases with altitude. This coldest layer of the atmosphere, where the lapse rate changes from positive in the troposphere to negative in the stratosphereis defined as the tropopause.

Atmospheric flow[ edit ] The flow of the atmosphere generally moves in a west to east direction. This, however, can often become interrupted, creating a more north to south or south to north flow.

These scenarios are often described in meteorology as zonal or meridional. These terms, however, tend to be used in reference to localised areas of atmosphere at a synoptic scale. A fuller explanation of the flow of atmosphere around the Earth as a whole can be found in the three-cell model. Zonal flow[ edit ] A zonal flow regime.

Note the dominant west-to-east flow as shown in the hPa height pattern. A zonal flow regime is the meteorological term meaning that the general flow pattern is west to east along the Earth's latitude lines, with weak shortwaves embedded in the flow. The region of the mesosphere is about 50 to 80 kilometers in altitude.

The composition of gases in the atmosphere from the ground to the top of the mesosphere, are almost identical except for water vapor and ozone. Therefore the region below the mesosphere is also called the homosphere. The thermosphere is the region above the top of mesosphere where the temperature begins to rise again.

Troposphere

When sun activity is low, this layer can extend to kilometers in altitude. During high sun activity periods the layer can reach around kilometers in altitude. The air in the lower region of the thermosphere is extremely thin; therefore the particles in the air can easily be ionized, resulting in profuse free electrons in the air. The sunlight heats the surface, and that surface radiates the heat into the adjacent atmosphere.

Atmospheric scientists use a concept called a "standard atmosphere" to represent an average atmosphere with variations caused by weather, latitude, season, and so forth, removed. Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops.

Troposphere - Wikipedia

Typically, the temperature drops about 6. The rate at which the temperature changes with altitude is called the "lapse rate".

Structure of the Atmosphere

Of course, the atmosphere is always changing and is never "standard". Temperatures in the troposphere, both at the surface and at various altitudes, do vary based on latitude, season, time of day or night, regional weather conditions, and so on.
