ATSC 210 Block 1 Exam Questions and Correct Answers (Already Graded A+) What is conserved for dry adiabatic processes? - Answer- Potential Temperature and Equivalent Potential Temperature Example of dry adiabatic process - Answer- Orographic lifting causing the parcel to cool, condense, and become dry on the leeward side. Define Mixing Ratio - Answer- The mass of water vapor to the mass of dry air. Define Equivalent Potential Temperature - Answer- The temperature a parcel would have ...

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...

WX 201 Exam 2 with correct Answers (Graded A) Dew is most likely to form on clear, calm nights Which two clouds can produce precipitation? cumulonimbus and nimbostratus If fog is forming in Denver, Colorado (located on the eastern side of the Rocky Mountains), and the wind is blowing from the east, then the fog is most likely upslope fog On a cold, winter morning, the most likely place for radiation fog to form is in a valley As Apollo 12 ascended into the atmosphere, th...

ATSC 113 SNOW EXAM QUESTIONS WITH ALL CORRECT ANSWERS Why is the orientation of the main shaft of a wind barb important? - Answer- It indicates the direction of the wind If you see four triangles on a wind barb at the elevation you're planning to ride, what does this indicate? Assume that the units as are they were presented in the snow learning goals. - Answer- A good day to stay inside and avoid skiing How might a weak pressure gradient be represented on a pressure map? - Answer- ...

Chapter 2, Lesson 3: Aviation Weather Questions and Answers (Certified Solutions) What allows small vertical movements to grow until they produce turbulent airflow and air circulation? An unstable atmosphere How does adiabatic heating heat dry air? Through compression How does adiabatic cooling cool dry air? Through expansion Where does the adiabatic process take place? In all upward and downward moving air What happens when air rises into an area of lower pressure? It expand...

WX201 Exam 2 Questions and Answers Graded A+ Stable If an object is displaced, it will respond in a manner than returns it to its original position Neutral Stability If an object is displaced it will remain at its new location Unstable If an object is displaced, it will continue to move away from its original position Positively Bouyant An air parcel is warmer than its environment it is what Negatively bouyant An air parcel is colder than its environment is what En...

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...
