How much altitude to you have to gain to lose 1 degree C in temperature?

Answer 1

Average temperature lapse rate is approx −0.0065 K/m (minus mean that temperature is lower at higher altitudes. Such temperature lapse rate is valid only below the tropopause).

Which means that you have to gain approx. 154 meters (or approx. 505 feet) to lose 1 degree kelvin (or celsius).

Answer 2

Stable air will tend to resist vertical motion. It will flow in a laminar fashion. Turbulence involves the air flowing any which way. Flying the hang-glider in unstable air will result in a bumpy ride with consequent difficulty in predicting the flight path of the glide. In stable air vertical motion is resisted so turbulent flow is restricted to two dimensions instead of three. The stability of the air can be defined as the tendency of the air to convect, or the tendency for vertical motion. Many people are unaware that the air changes in this way. On a stable day the air will prefer to flow around a hill rather than up and over it and changes of surface temperature will not result in rising warm air currents. The options for soaring flight will be limited: a ridge facing the wind, or a bowl, will force the air to rise over it , there is no alternative route, however, little height will be gained by the soaring hang-glider. In unstable air the flow becomes chaotic. Rising air will continue to rise and be replaced by falling air, an object in the path of the wind will give rise to turbulence which may continue long past the object, (tree, building, etc.,), and may even increase! The hang-glider will be in for an unpleasant ride.. The air can be stable at one level and unstable at another; and, during the day, the degree of atmospheric instability will change. This condition of the air depends upon the change of temperature with height. If there is little or no change the air will be stable, when the air cools rapidly with gaining height the air will be unstable. This change of temperature with height is called the lapse rate. On any particular day at a certain time we could measure the lapse rate by ascending in a balloon recording the temperature every, say, 100ft. Usually we will find a gradually reducing temperature as we gain height, about 2 degrees C per 1000ft., but often a layer of warmer air is found, this is called a temperature inversion, (because it rises instead of the usual fall). There is another type of lapse rate that varies with the humidity of the air called the adiabatic lapse rate. If we take a parcel of air and move it upwards it will lose temperature because of the reducing pressure with altitude. This lapse rate is again a plot of temperature-change with height, but this time, for our "parcel of air" at different heights because of the lowering air pressure, (hence, "adiabatic"). Wet air, or saturated air, only loses about 1.5 degree C per 1000ft., whereas dry air loses some 3 degrees C per 1000ft. This is because the water vapour gives out energy on condensing, releasing it's latent heat of evaporation. A parcel of air will rise when it's temperature is greater than the surrounding air, being warmer it has lower density. As it rises it will lose temperature according to its adiabatic lapse rate. It will also cool somewhat due to the air mixing. If the atmospheric lapse rate is less than the adiabatic lapse rate, the rising air will soon reach the temperature of the surrounding air and so will stop. When the atmospheric, (environmental), lapse rate is similar to the adiabatic lapse rate the warm air parcel will continue to rise until the temperature is equalised by mixing with the cooler surrounding air. If the atmospheric lapse rate is "super adiabatic" then the air will be spontaneously unstable, any upward movement of the air actually becomes warmer than its surroundings and continues. This state of affairs will not last long as the upcurrents will redistribute the heat, warming the upper layers, reducing the atmospheric lapse rate to a more stable condition.

Answer 3

How long is a hunk of string? Its the same kind of question.

There is NO rate of (ABSOLUTE) temp loss per foot. There can never be because each foot of atmosphere is different from the one next to it.

I have flown up and have had the temp go up as well. call a "temperature inversion"

Answer 4

One degree celcius per 100 meters

Answer 5

if you were educated like a true and proud illegal mexican like me, you would know u loose 2 degree celsius per 1000 feet.

so 500 feet for 1 degree.
minimum is -56 at the top of the troposphere...


from mexico...

Answer 6

I am afraid it depends to some extent on the airmass present. It is called adiabatic lapse rate.

The rough value is what the guy above said.

Answer 7

For every increase in height about 165metres, you will lose 1degree Celcius.

Answer 8

never trust the answers of a mexian for a start

Answer 9

165metres

Answer 10

i dont know -sorry
