WX 201 - Exam 2 Chapter 6-10 Questions and Answers The elevation where clouds form is called ____ level. condensation If the environmental lapse rate is 5 ° C per 1,000 m and the temperature at Earth's surface is 25 ° C, then the air temperature at 2,000 m above the ground is 15°C. What transfers heat upward into the atmosphere? thermals Just above cumulus clouds, you would expect to find a stable layer. If an air parcel is given a small push upward and it falls back...

Standard Atmosphere was created by: Averaging conditions to create an idealized atmosphere. The standard temperature lapse rate in the lower layers of the atmosphere is: A decrease of 2° C per 1,000'. If the air temperature is +8°C at an elevation of 1,350 feet MSL and a standard (average) temperature lapse rate exists, what will be the approximate freezing level? 5,350 feet MSL. Moving up in the atmosphere, unsaturated air gets cooler at approximately what rate (dry adiabatic lapse ra...

Thunderstorms which generally produce the most intense hazard to aircraft are? Squall line thunderstorms What are the processes by which moisture is added to unsaturated air? Evaporation and sublimation Why is frost considered hazardous to flight? Frost spoils the smooth flow of air over the wings, and therefore decreases the lift capability of an aircraft Clouds, fog, or dew will always form when Water vapor condenses Clouds are divided into four families according to their Height range ...
