What is the temperature profile of the atmosphere?
According to the International Civil Aviation Organization (Doc 7488-CD, 1993), the standard atmosphere has a temperature of 15 oC at the surface, a lapse rate of 6.5 oC km–1 from 0 km to 11 km, a zero lapse rate from 11 km to 20 km, and a lapse rate of –1 oC km–1 from 20 km to 32 km in the stratosphere (i.e..
What determines the air temperature?
The temperature of the air is caused by the combination of air, water, and land working together. Those three factors heat and cool areas at different rates. Temperature also varies by the time of day, the season, or even the year.
What is temperature profile definition?
Temperature profiling is the term used to describe the process of recording and interpreting the temperatures of products and/or air through a conveyorized heat-treating process.
How will you describe the air temperature at this elevation?
How does elevation affect temperature? Atmospheric pressure is simply the weight of the air pushing down on you from above. As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.
What is temperature distribution?
Temperature distribution is a solution of the equation of linear flow of heat [1]:(1) ∂ T ∂ t =α ∂ 2 T ∂ x 2 , where T=T(x,t) is the temperature in space–time point (x,t) and α is the thermal diffusivity. It is in contradiction with the theory of relativity and also with known mechanisms of heat conduction.
What are the five factors that determine air temperature?
Five important factors influence air temperature:
- Latitude. Daily and annual cycles of insolation vary systematically with latitude, causing air temperatures and air temperature cycles to vary as well.
- Surface type.
- Coastal or interior location.
- Elevation.
- Atmospheric and oceanic circulations.
What is normal air temperature?
NTP – Normal Temperature and Pressure – is defined as air at 20oC (293.15 K, 68oF) and 1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 29.92 in Hg, 407 in H2O, 760 torr).
What causes this vertical profile?
Due to the absorption of sunlight in the upper layer of the oceans, combined with density separation by depth, a vertical temperature profile is established in the water of the oceans. These differences are enhanced at certain areas through the action of ocean currents.
