  4. Wed. 5/8 and Thurs. 5/9 • If you were absent last class, you missed a test and INB check.

  5. Which weather tool is used to measure the average energy of the particles present? • Barometer • Anemometer • Thermometer • Psychrometer

  6. In: pg. 96 Weather ABC Chart • Fill in as many terms related to weather as you can. • You need at least 10! • Please number them.

  7. Thru 1: Pg. 97 Movie: Lightning! • 15 facts

  8. Thru 2: Pg. 98-99Use pages 611-613 of the textbook Weather Instruments Wind Vane Thermometer Barometer Anemometer Radiosonde Radar • Definition • 2 facts

  9. Out • Make sure you ABC chart has 20 terms on it.

  10. Fri. 5/10 or Mon. 5/12

  11. A parcel of hot, moisture-laden air rises within the atmosphere.  Which occurrence is UNLIKELY to follow?  The parcel of air will • get warmer and continue to rise. • get cooler and stop rising. • begin to condense into a cloud. • begin to precipitate.

  12. In: pg. 100 • What is the weather like today? • What is the climate of Las Vegas? • What is the difference between weather and climate?

  13. Chapter 23 Weather Pg. 101 Cornell Notes

  14. Weather Versus Climate • Weather is what is happening in the atmosphere over a few hours or days. • Climate is the overall weather of an area.

  15. Who studies weather? • Meteorologist-scientist who studies the weather.

  16. What controls the weather? • Short answer – AIR MASSES • Body of air that is characterized by similar temperatures and amounts of moisture at any given altitude.

  17. CLASSIFIED BY >>> • WARM or COLD • Warm - tropical (forms near equator) • Cold - polar (forms near poles) • WET or DRY • Wet – maritime (forms over bodies of water) • Dry – continental (forms over land)

  18. WHAT ARE THE AIR MASSES FOR THE UNITED STATES?

  19. COLLISIONS OF AIR MASSES • When two air masses collide, that boundary is called a FRONT. • FOUR TYPES • Warm Front • Cold Front • Stationary Front • Occluded Front

  20. NAMING FRONTS • The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass.

  21. COLD FRONT • The cold air mass is replacing the warm air mass. • The air behind a cold front is colder and typically drier than the air ahead of it

  22. WARM FRONT • A cold air mass is receding. • Favors the development of widespread, continuous precipitation

  23. STATIONARY FRONT • A front that is not moving. • Stationary fronts can also produce significant weather and are often tied to flooding events

  24. OCCLUDED FRONT • Cold fronts move faster than warm fronts. • Sometimes in a storm system the cold front will "catch up" to the warm front. • Which ever air mass is the coldest undercuts the other.

  25. Types of Fronts Warm Front Cold Front Cold air and warm air stand still Stationary Front Map Symbol Occluded Front Stationary Front

  26. Jet streams • A jet stream is a narrow band of high-speed winds that blow in the upper troposphere. • Form at the boundary between a cold air mass and a warm air mass. • Flow along the boundary. • Push storms and other weather around.

  27. Thru 2 Pg. 102 3 Column Vocab • Air mass • Continental air mass • Maritime air mass • Cold front • Warm front • Occluded front Pg. 103 7. Stationary front • Isobar • Isotherm 10. Tornado • Hurricane 12. Meteorologist

  28. Out • What type of front is this? • How do you know?

  29. Tues. 5/14 and Wed. 5/15

  30. Which statement best describes weather?  Weather is • very easy to predict, as the atmosphere is very stable. • an average of the atmospheric conditions in an area over a long period of time. • the current conditions of the atmosphere at a certain time and place. • an average of the atmospheric conditions in over a short period of  time.

  31. In: pg. 104 • What is the abbreviation for each type of air mass? • Maritime polar • Maritime tropical • Continental polar • Continental tropical • 2. What type of air mass is over Nevada?

  32. Thru 1: pg. 105 4 Types of Fronts • Draw and label each type of front. • Color warm air red and cold air blue

  33. Cold Front

  34. Warm Front

  35. Occluded Front

  36. Stationary Front Stationary Front Map Symbol

  37. Thru 2 Pg. 106 • Learning to Read a Weather Map • Tape this in as reference. Pg. 107 • Reading a Weather Map Worksheet. • Complete the questions on the back using the map on the front.

  38. Out • What are 5 pieces of info. a weather map gives you?

  39. Thurs. 5/16 and Fri. 5/17

  40. Why might a meteorologist compare a new weather map to one that is a day old? • The weather conditions yesterday can accurately predict what type of weather will occur today. • A comparison of the maps can help determine how fast fronts are moving. • Meteorologists never compare current weather maps with day old maps. • If an area experienced precipitation one day, it will experience precipitation the next day.

  41. In: pg. 108 Use the weather map at your desk to answer the following questions: • In Las Vegas, what was the • Date? • High temp? • Low temp? • Wind direction? • Wind speed? • Cloud cover? 2. On the National Map, • What types of front(s) were moving across the country? • Where was there precipitation? • What kind was it?

  42. Thru 1: pg 109 • http://www.cbsnews.com/video/watch/?id=50134142n Article: Submerged City • Read the article and answer the questions.

  43. Thru 2 Pg. 110 Pg. 111 Tornado Coloring Book • Color the arrows representing rising hot air red and arrows representing falling cold air blue.

  44. Out • Is a hurricane likely to hit Las Vegas? Why or why not?

  45. Mon. 5/20 and Tues. 5/21 • Test and INB check next class.
