PLEASE ANSWER ALL QUESTIONS. THANK YOU
6.The Stuve diagram showed by the separation of the temperature and dewpoint values at the surface and above (up to about 935 mb), that the surface air ________ saturated. This was confirmed by the Figure 1 observations of the Jackson surface temperature and dewpoint.
[ ] was
[ ] was not
7.The temperature profile from the surface up to about 935 mb over Jackson was essentially parallel to the ________ adiabatic lapse rate lines printed on the diagram. This was evidence of surface air moving upward and cooling by expansion at the unsaturated adiabatic lapse rate.
[ ] straight, solid, green dry
[ ] curved, dashed, blue saturated
Careful inspection of the profiles shows that temperatures decreased quickly in the first few tens of millibars and there was a slight decrease in dewpoints as well. This was due to the
influence of ground conditions. Then, starting at about 935 mb, there was a temperature inversionextending to about 905 mb. This was due to the advance of warmer air upward above the frontal surface, ahead of the position of the surface front. Note how the winds also shifted at the base of this layer, coming from the south (the location of the Gulf, relative to Jackson). Finally, the air again returned to cooling by expansion above this inversion layer.
8.Air rising from the surface above Jackson cooled, and at about 935 mb, its temperature and dewpoint ________ become equal.
[ ] did
[ ] did not
9.The air over the Jackson area at 935 mb therefore ________ saturated.
[ ] was
[ ] far from being
10. Table 1 displays selected values from the Jackson rawinsonde in their raw, numeric format. Table 1 focuses on the lowest layer of the air mass as described in Item 7. This was the interval shown on the Stuve diagram (Figure 2) to be following adiabatic expansional lift. The temperature difference between the bottom (1007 mb) and top (936 mb) of this layer in Table 1 was ________ °C over an altitude change of 627 m. Therefore, this temperature lapse rate of 6.2°C per 627 m was essentially equivalent to ________ °C per kilometer (1000 m).

6.As the jackson surface shows that the difference between temparature and dew point is not very high so we can predict that the air above 935 mb was saturated but the below air was not saturated .ButBut as per the question is concerned the answer is the air was saturated.
7.If you observe the Jackson surface carefully you can observe the cooling of air as it goes up.For details we can take the example as the surface air is effected by the surface temperature so the air is warmer but above 935 mb the air becomes cool up to 905mb.So the Jackson is parallel to the straight,solid,green dry lapse rate line.
8.This is a simple question as described above we have observed that the temperature goes down as the air goes up so we have noticed that at 935mb the temperature and dew point curve cuts each other that means they did become equal .
9.This question is a conclusion of above three questions as we knew the air temparature and dew point become equal at 935mb so above it the air must be saturated .
