Question

f emperature o20 Ca pressure d 1s /z, and a vapor mixing ratio ofSgk ons 11. to 18. are based on the following conditions. A parcel of air an altitude above of ground of . a saturation vapor mitipg ratio The pareel is liftrd dry adiabaticaly- rem 1000 mbt ground 900 mDwhichrts roughly 1000 meter above the ground. 1. The relative humidity of the parcel air at 1000 mb is% 90 b. 33 c. 50 d. 67 12. The a. 25 20 the parcel air at 1000 mb is roughly eC d. 10 13. The temperature of the lifted parcel at 900 mb is a. 25 0. d. 10 20C e. b. 20 c. Is 14.
