Question
Correcting direct pressure values to sea level. A general guide for correcting direct pressure readings to sea level is that: “…near the Earth's surface, pressure decreases about 10 millibars for every 100 meters ascent in elevation…” a. A weather observer at a location in Denver, Colorado, at an elevation 1600 meters above sea level, observes a direct pressure reading of 847 mb. Estimate the sea-level pressure for Denver in units of millibars. Also provide your answer in units of inches of mercury. b. A weather observer at a location in Death Valley, California, at an elevation 80 meters below sea level, observes a direct pressure reading of 1016 mb. Estimate the sea-level pressure for Death Valley in units of millibars. Also provide your answer in units of inches of mercury. (Be sure to show your calculations).
Explanation / Answer
a. 847- 160 mb = 787 mb or 23.24 inch of mercury
b. 1016+ 08 mb = 1024 mb or 30.23 inch of mercury
