WEAX 201 Module 4 EOM Questions with Correct
Answers
Which condition below could make a layer of air more unstable? ✔✔- cool the upper part of the layer
- mix the air in the layer
- lift the entire air layer
- *ALL OF THE ABOVE*
What would the air temperature inside a conventional jet airliner be, if outside air at an altitude of 10
km, pressure of 250 mb and a temperature of -60 oC, is brought inside and compressed to a 1000 mb
pressure? (Hint: you may assume that 1000 mb pressure is equivalent to 0 m altitude) ✔✔40 C
Which cloud type would most likely form in absolutely stable air? ✔✔stratus
In a rising thermal, the dew-point temperature: ✔✔decreases at a slower rate than the parcel
temperature
The atmosphere can become more unstable due to:
Select all answers that apply. ✔✔- air moving over a cooler surface
- * winds bring in cold air (cold advection) aloft
- winds bring in warm air (warm advection) aloft
- * winds bring in warm air (warm advection) at the surface
- * daytime solar heating of the surface
