Decoding the Coded Pressure 196 Insert a decimal point to the left of the last digit 19.6 Put a “9” and a “10” in front of the result 1019.6 919.6 Test the results against the range of normal atmospheric pressures 919.6 is below the range of normal pressures…. REJECTED! 1019.6 is within the range of normal pressures…. ACCEPTED! Coded pressure196= 1019.6mb Decode these coded pressures: 002 993 280 000 1028.0 1000.0 999.3 1000.2 How to encode pressures Back to the Station Model ©S. Kluge 2007
Encoding the Pressure 1013.5 Remove the decimal point 10135 Report the last 3 digits 135 Pressure1013.5 = 135 encoded pressure Encode these pressures: 1032.7 987.3 1012.2 1000.1 327 873 122 001 Back to Decoding Pressures Back to the Station Model ©S. Kluge 2007
The Barometric Trend + 19 / + means “Higher now than it was 3 hours ago” (- means “Lower now than it was 3 hours ago”) 19means the pressure has changed by 1.9 mb / means the pressure is currently rising (\ means the pressure is currently falling) What was the pressure 3 hours ago? Here? 1003.5 1017.7 Back to the Station Model ©S. Kluge 2007
