Troposphere - Wikipedia
As we keep on going higher and higher, temperature falls till we reach the top of the troposphere (except for the region known as tropopause), where the. The troposphere is the layer of the atmosphere closest to the earth's surface where the weather takes place. The warmest temperatures in the troposphere are . The temperature in the troposphere usually decreases with height at the average lapse rate of °C per kilometer. The air in the troposphere is more unstable.
The troposphere is coldest at its top, where it meets up with the layer above the stratosphere at a boundary region called the tropopause.
Temperatures drop as you move upward through the troposphere. Sunlight streams down from space through the atmosphere, striking the ground or ocean beneath.
- Relationship between temperature and height in the troposphere
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.
Typically, the temperature drops about 6. The rate at which the temperature changes with altitude is called the "lapse rate".

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.
The troposphere is about 12 kilometers thick on average; it is thicker in summer than in winter.
The troposphere over low latitude regions is usually thicker than over high latitude regions. The troposphere over the equator is about 18 kilometers thick, while its thickness in the regions nearest the two poles is only about eight to nine kilometers.
The temperature in the troposphere usually decreases with height at the average lapse rate of 6. The air in the troposphere is more unstable and with strong convection. Almost all the water vapor in the atmosphere exists within this layer; therefore, common weather phenomena such as clouds, fog, rain, and snow, occur only in this layer and more often than not in its lower part.
The stratosphere extends from 10 kilometers to 50 - 55 kilometers above ground. Within the lower part which extends from the top of the troposphere to about kilometers the temperature is almost constant, or increases slightly with height.
Since almost no dust or water vapor from the land surface will reach the stratosphere, the air flow in this layer is steady. The upper part of the stratosphere experiences an increase of temperature due to the fact that the sun's ultraviolet radiation is absorbed by the ozone layer.
The region of the mesosphere is about 50 to 80 kilometers in altitude.
