The density of the atmosphere is proportional to the heat it's containing; so, it's density 100km over the tropics isn't quite the same as it's density 100km over the poles. However, over the course of a year, depending on your location, the atmosphere will receive more direct sunlight and heat up, causing it's density to fall, then cool off, causing it's density to increase.
In other words:-Atmospheric drag is reduced as altitude and
temperature increase.
Because the density of the air is reduced at higher altitude and
temperature.
Hope my explanation will help you.

1. For an atmosphere in hydrostatic equilibrium the variation of particle number density (# of particles per unit volume) of each species as a function of altitude (z) is found by equating gravitational and pressure forces. The resulting expression is: N(z) = No * e^(-(z - zo)/H) where N0 is a constant for each species, and z0 is an arbitrary reference altitude. The parameter H is called the scale height, which is equal to KT/mg. In the scale height expression...

How does the density of wildebeests grazing on Panicum grasses change over time after the peak rain? a. Wildebeest density is relatively constant throughout the six months following the rain. b. Wildebeest density reaches its maximum one month after the rain but then decreases to nearly zero about three months after the rain. Six months after the rain, however, the density has increased slightly. c. Wildebeest density is very low for two months after the rain but then begins to...

An airplane of mass 10,000 kg is flying over level ground at a constant altitude of 4.30 km with a constant velocity of 165 m/s west. Its direction is currently straight toward the top of a mountain. At a particular instant, a house is directly below the plane at ground level. (a) At this instant, what is the magnitude of the plane's angular momentum relative to the house (in kg m-/s)? kg. m/s (b) As the plane continues its constant...
