The most rapid temperature increase ever recorded was 27 C° (49 F°) in 2 minutes, recorded at Spearfish, SD, on January 22, 1943, at 7:32 a.m. At 7:30 the temperature was -4°F (-20°C), a downslope Chinook wind brought the temperature up so that 2 minutes later (7:32 a.m.) the temperature was +45°F (+7°C) above zero. How many kilometers would a parcel of air have to sink to raise its temperature by 27 C° (49 F°)?
