The reason the temperature increases with height is because of the ozone layer. True airspeed in knots at which the turn requirement above has to be met. Optional, defaults to 0. Definition of a virtual atmosphere object. A list of two lists, specifying the location and color of vertical marker lines e. However, the temperatures in this layer are known to vary greatly depending on the season we are jet planes fly in stratosphere python. Off-standard, temperature offset versions of the above.

This mixture of gasses we call air. Because the Earth spins on its axis, and because the surface temperature is greater at the equator than at the poles, the atmosphere extends further out into space at the equator than at the poles. Air Density decreases with increasing altitude. The top of the stratosphere occurs at an altitude of 50 km 31 miles. The height of the bottom of the stratosphere varies with latitude and with the seasons.

The lower boundary of the stratosphere can be as high as 20 km 12 miles or 65, feet near the equator and as low as 7 km 4 miles or 23, feet at the poles in winter. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause.

Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun.

Temperatures rise as one moves upward through the stratosphere. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below.

The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere. Polar stratospheric clouds PSCs are the exception. The ocean of Storms is the name given to-. Which one of the following zones of the atmosphere is rich in ozone gas?
