10. What is the barometric pressure 998.7 is nearer to 1013 than 1098.7 Answer: 998.7 mb In tenths of mb

Slide 10

11. What was the barometric pressure three hours ago? 998.7 minus 1.1, since the barometer has been rising, it was lower in the past, and the amounts are reported to the nearest tenth of a millibar Answer: 997.6 mb In tenths of mb
