Presentation Transcript

  1. Class 1 Friday 5/5 Do Now: - Take out the "Weather Maps" worksheet you completed on Wednesday. This worksheet is on the back of the "Air Masses" worksheet.

  2. Cold Front, moving South Isotherm, connects equal temperature Occluded Front Warm Front, moving East Stationary Front Isobar, connects equal pressure

  3. Aim: How are weather maps created?

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

  5. 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? Station models make reading data easier on a map

  6. B. Isotherms: - lines that connect points of equal air temperature. - Isotherms are usually drawn as lines across the map or page 500 600 700

  7. C. Isobars: - lines that connect points of equal air pressure. Usually drawn as circles on the map - show centers of high and low pressure High pressure has high numbers at it center Low pressure has low numbers at it center

  8. 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 (isobars = circles) or run off the page (isotherms = lines). 4. Isolines must be labeled with their value.

  9. Closure 1: Take the “Drawing isobars and Isotherms” worksheet from the back Top bin.

  10. Closure 2: Review Book p.340-341 # 1-5 Do the reading on page 340 to better help you answer the questions Answers: 3 2 3 1 4 1. 2. 3. 4. 5.

  11. Closure 3: Review Book p.368 # 7-9

  12. Class 2 and 3 Friday 5/5 Do Now: - Take out the “What is a Front" worksheet you completed on Thursday.
