  1. Topic: Air Pressure • ___

  2. The air is made up of molecules.

  3. kg Air molecules have mass.

  4. Standard air pressure at sea level = 14.7 lbs/in2

  5. Air pressure is equal in all directions.

  6. Cold front came through (more dense) , warm grains inside (warm air), crushed silo.

  7. TRAIN

  8. What happened to the can?

  9. Air pressure is: • _ • _ • _

  12. High pressure is - Low pressure is -

  13. Conversions – page 13 ESRT!

  14. Millibars 1040.0 973.0 Inches - - PressureConversions

  15. Inches 29.44 28.70 Millibars - - Pressure Conversions

  16. Pressure into Station Model Code • EX) 1019.6 mb = 196 on station model 196

  17. If the number is… • - • Ex: -

  18. - Ex: -

  19. On the map – upper right hand corner 500 or greater put a 9 in front 499 or less put a 10 in front Remember to add the decimal after the last digit. 196 196 19.6 19.6 1019.6 919.6 Station Model Code into Millibars 196

  20. What is possible? 1019.6 919.6 Check your answer Too Low! No good!

  21. More Examples 419 • What is the pressure in millibars? = 419 419 41.9 41.9 1041.9 941.9 Short Method: if the code is 500 or higher put a 9 in front, otherwise put a 10 --- Change 996.3 mb onto a station model

  22. 002 = FQ: What is the correct pressure for this weather station? Final Question
