1. Introduction to Weather Map Eric Angat Teacher

2. 1. What is a Weather map? A weather map shows facts about the weather at a place. A weather map can show the temperature through isotherms ( temperature) and air pressures through isobars ( pressure).

3. 2. What are the types of fronts in this weather map? 3. What type of front is approaching North Carolina? 4. What kind of weather will North Carolina have in the coming days? Stationary front- Persistent weather Warm front Cold front Thunderstorm

4. 5. Find the following data. a.Temperaturec. Air pressure b.Direction of windd. Current weather Temperature Atmospheric pressure Wind direction Southeast North East South West P. 317 Rain is the current weather.

5. 6. Which direction is the wind blowing at this weather station? A. northeast B.northwest C.southeast D.southwest

6. P. 915

9. More water vapor water vapor cools condensation precipitation

10. 7. On an August afternoon in North Carolina, the barometric pressure is 29.92 inches and falling. What weather condition is likely to happen? A.clearing skies and cooler temperatures B.continued fair weather C.an imminent storm D.conditions will slowly improve Decreasing air pressure means bad weather is coming.

11. 8. Describe the weather in areas where there are “L” and “H”. 9. What is the general direction of wind in the United States? 10. How do you know the direction of a front? Think!

13. 8. Describe the weather in areas where there are “L” and “H”. 9. What is the general direction of wind in the United States? 10. How do you know the direction of a front? Think! L means bad weather and H means good weather. Westerly wind ( West to East) The direction of the front is where the flagllets are pointing.

14. 11. How does Orographic Precipitation happen? https://www.youtube.com/watch?v=GJR893xiTr0

15. Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. http://en.wikipedia.org/wiki/Orographic_lift http://earthscience-in-the- nationalparks.wikispaces.com/Death+Valley
