5) Flight conditions associated with the tropopause {Ans: The tropopause is important to aviators for several reasons. The strongest winds, those of the jet stream, occur just below the tropopause. Moderate to severe turbulence is sometimes associated with the wind shear caused by the jet stream. Contrails frequently form and persist near the tropopause since it is normally the coldest area within the lower atmosphere. While clouds and weather are generally confined to the troposphere, severe thunderstorm tops may penetrate the tropopause into the stratosphere. You can sometimes identify the tropopause while in -flight by the following characteristics: the average height of the tropopause over the US is 36,000 feet MSL, anvil tops of thunderstorms will spread out at the base of the tropopause, and a haze layer with a definite top frequently exists at the tropopause.}Using the standard lapse rate, a pilot flying at 10,000 ft MSL and at a temperature of -8° C should do what to find an altitude at which the temperature is +4 °C? {Ans: Descend to approximately 4000 feet MSL}The two lower layers of the atmosphere are the ______ and ______, {Ans: troposphere ; stratosphere}Which one of the following items would
