ATSC 110 Test 2 Questions and Answers All Correct What is an unstable atmosphere? - Answer- When a parcel of air remains warmer than the surrounding air while being lifted, we say the air is unstable. In other words, when the environmental lapse rate is greater than the dry lapse rate (10°C/km) the atmosphere is absolutely unstable. What conditions cause an unstable atmosphere? - Answer- The environmental lapse rate is large (steep) when unstable conditions prevail. In other words the d...

WX 201 Exam 2 with correct Answers (Graded A) ____ is a condition in which the environmental lapse rate is equal to the dry adiabatic rate. Neutral stability The rate at which the actual air temperature changes with increasing height above the surface is referred to as the ____ rate. environmental lapse Absolute instability results when the environmental lapse rate is ____ the ____ adiabatic rate. greater than; dry An air parcel in an unstable atmosphere has ____ force acting ...

ATSC110 Final Exam Latest Version Real Exam Questions and Correct Answers (A Grade) Which of these conditions will cause the atmosphere to become more unstable? - Answer- increasing the surface temperatures while decreasing the temperatures above the surface The environmental lapse rate was 5⁰C/km during the morning but changed to 8⁰C/km by late afternoon. Due to the change in the environmental lapse rate, the atmosphere become: - Answer- more unstable Thunderstorm development will n...

WX 201 Exam 2 with correct Answers (Graded A) An unsaturated air parcel cools or warms at what rate? Dry adiabatic lapse rate (DALR) A saturated air parcel cools or warms at which rate? Moist adiabatic rate (MALR) If the environmental lapse rate is greater than the dry adiabatic rate, the atmosphere is: Absolutely unstable Surface cooling and warm air advection aloft generally do what to the atmosphere? Make it more stable An air parcel starts to rise freely when it firs...

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...

A 30 degrees Celsius parcel at 1 km is lifted to a height of 2 km at the moist adiabatic rate of 7 degrees Celsius per kilometer. The environmental temperature at 1 km is 30 degrees Celsius and the environmental lapse rate is 11 degrees Celsius per km. What is the stability of the parcel after lifting? - ️️absolutely stable A 30 degrees Celsius parcel at 1 km is lifted to a height of 2 km at the moist adiabatic rate of 7 degrees Celsius per kilometer. The environmental temperature at 1 km i...
