    1. The Surface Station Model

    3. Sample Surface Station Model

    4. Complete Surface Station Model

    5. Typical Surface Station Model Based on METAR Data

    6. Sky Cover Symbols

    7. Wind Speed and Direction Wind speed and wind direction are plotted using a wind arrow. The wind direction is plotted with the wind arrow indicating the direction of the wind blowing into the station circle.

    8. Wind Speed Wind Speed is indicated by the number of half barbs, whole barbs, and flags. The wind speed is indicated by the sum of the wind speeds represent by the half barbs, whole barbs and flags.

    9. Wind Speed

    10. Wind Speed

    11. Wind Speed (cont.)

    12. Wind Speed (cont.)

    13. Wind Speed (cont.)

    14. Wind Speed (cont.)

    15. Three Hour Pressure Change Characteristic

    16. Low Cloud Symbols

    17. Middle Cloud Symbols

    18. High Cloud Symbols

    19. Present Weather Symbols

    20. Online Symbols A good source of information about the symbols used in the surface station model is http://www.shr.noaa.gov/jetstream/synoptic/wxmaps.htm
