1. Aim: How are weather maps created?

2. I. Weather Maps:
Track different air masses and are used to forecast future conditions. (shows a lot of data)

3. Why would meteorologist use station models to represent data on a map?
A. Station Models:
Page 13 ESRT
- Symbols on a weather map that give data on many weather variables.
Why would meteorologist use station models to represent data on a map?

4. B. Isotherms:
- lines that connect points of equal air temperature.

5. C. Isobars: - lines that connect points of equal air pressure.
- show centers of high and low pressure
High pressure has high numbers at it center
Low pressure has low numbers at it center

6. II. Rules for Drawing Isolines:
1. Isolines do not touch or cross.
2. Isolines are drawn parallel to each other.
3. Isolines form closed loops or run off the page.

7. Closure:
Take the worksheet from the back bottom bin.
