air temperature and altitude relationship

As you increase altitude, the air gets increasingly rarer, which leads to a loss of pressure. Temperature is directly proportional to pressure, so the lower the. In the Earth's atmosphere, temperature varies greatly at The coldest temperatures lie near the mesopause. Standard values for pressure, temperature and density (ignoring the slight effect of humidity) at altitudes from sea level to 16, feet (about m).

Temperatures in the troposphere drop an average of 6.

Five kilometers up, the temperature would be 15 - 5 x 6. This rough equation remains reasonably accurate up to the tropopause.

Sciencing Video Vault Estimate the the temperature at the altitude of your choice in the tropopause. The tropopause maintains a more or less steady temperature from bottom to top at higher latitudes.

In fact, the tropopause is in part defined by this thermal stability. The temperatures measure roughly degrees C at 75 degrees latitude, degrees C at 60 degrees latitude and degrees C at 45 degrees latitude. Closer to the equator, the tropopause continues to cool.

Atmospheric temperature - Wikipedia

At 30 degrees latitude, the temperature falls to degrees C at 15 km altitude before starting to rise. At the equator, the temperature hits degrees C around 17 km high before rising.

The average temperature of the entire tropopause is a steady degrees C. The tropopause is coldest over the equator and warmest over the poles because as warm air rises and expands, it sucks up heat energy and cools the atmosphere.

The more the air expands, the more it cools the surroundings -- and warm air expands more than cold air.

In contrast, some of the warmest temperatures can be found in the thermospherewhich receives strong ionizing radiation at the level of the Van Allen radiation belt. Temperature varies as one moves vertically upwards from the Earth's surface. It also depends on the change of latitude. Temperature range[ edit ] The variation in temperature that occurs from the highs of the day to the cool of nights is called diurnal temperature variation.

Temperature ranges can also be based on periods of a month, or a year.

The size of ground-level atmospheric temperature ranges depends on several factors, such as: The average temperature The regime of winds intensity, duration, variation, temperature, etc. Average yearly temperature is The average temperature range is It is easy to see in the graph another typical phenomenon of temperature ranges, which is its increase during winter lower average air temperature.

In Campinas, for example, the daily temperature range in July the coolest month of the year may vary between typically 10 and 24 degrees Celsius range of 14while in January, it may range between 20 and 30 degrees Celsius range of
