Aim: How do we put all four atmospheric variables on a weather map? Topic: Meteorology (Unit 6) Main Idea: Station Models

1) What are the four atmospheric variables?  A) Temperature  B) Air pressure  C) Humidity  D) Winds

Station 1 These are station models. Which of them represents an area that is warm and about to rain? Prove it from your ESRT’s.

Station 1 What is a station model?  It is a small symbol on a weather map with all the atmospheric variables shown.

Station 2 Where does the barometric pressure go on a station model?  It is shown with three numbers in the upper right corner.  A= mb B= mb C= mb D=967.9 mb E=994.1 mb F=982.1 mb

If the number on the station model is below 500 you should _________________ __________________; if the number is 500 and up you should ____________________ ________________________.

Exit Card: 1) Convert the pressure 2) What is the wind speed and direction 3) What is the present weather?

Do Now  Answer the questions on the back of yesterday’s notes.

4) How do we convert atmospheric pressure to put onto a station model?  We use the last three numbers to put it on the station model.
