Severe Weather Investigation 5-2

  1. 1. Severe Weather Investigation 5-2
  2. 2. Weather <ul><li>What is Weather? How would you describe the weather today? </li></ul><ul><li>Weather is the condition of the atmosphere (air close to Earth’s surface) </li></ul><ul><li>Can be described in terms of several weather factors, or weather variables </li></ul>
  3. 3. Important Weather Variables <ul><li>Amount of water in the air </li></ul><ul><ul><li>Humidity, rain, snow, fog, or clouds </li></ul></ul><ul><li>Amount of movement in the air </li></ul><ul><ul><li>Wind </li></ul></ul><ul><li>Amount of heat in the air </li></ul><ul><ul><li>Thermometer measures temperature </li></ul></ul>
  4. 4. <ul><li>When weather factors are all mild - weather is good </li></ul><ul><ul><li>Clear, calm, and warm </li></ul></ul><ul><li>When one or more factor is intense - weather is bad </li></ul><ul><ul><li>Uncomfortably wet, dry, windy, hot, or cold </li></ul></ul><ul><li>When one or more factor is dangerously out of typical range - weather is extreme - Severe weather </li></ul><ul><ul><li>Stormy with heavy amounts of rain or snow, intensely windy, dangerously hot or cold, or other combination of extremes </li></ul></ul>
  5. 5. Today’s Weather <ul><li>Comment on today’s weather in terms of three main variables </li></ul><ul><ul><li>Moisture, heat, movement </li></ul></ul><ul><li>Moisture </li></ul><ul><ul><li>Water evaporates, becomes water vapor </li></ul></ul><ul><li>Heat </li></ul><ul><ul><li>Solar energy heats surface, heat transfers to air molecules </li></ul></ul><ul><li>Movement/Wind </li></ul><ul><ul><li>Uneven heating produces air masses of different temperatures and densities </li></ul></ul><ul><ul><li>Denser air flows under less dense air </li></ul></ul><ul><ul><li>Flowing air mass is wind </li></ul></ul>
  6. 6. Severe Weather <ul><li>How do everyday weather events turn into severe weather? </li></ul><ul><li>Turn to page 227, Severe Weather </li></ul><ul><li>Complete Severe Weather Questions </li></ul><ul><li>What causes tornadoes? </li></ul><ul><li>What causes hurricanes? </li></ul><ul><li>How does the water cycle affect weather in California? </li></ul><ul><li>How does the ocean influence the weather in California? </li></ul>
  7. 7. Vocabulary <ul><li>Weather variables </li></ul><ul><ul><li>Include amount of moisture, movement, and heat in atmosphere </li></ul></ul><ul><li>Severe weather </li></ul><ul><ul><li>Extreme and out of the ordinary in one or more ways </li></ul></ul><ul><li>Hurricane </li></ul><ul><ul><li>Huge column of spinning air and water </li></ul></ul><ul><ul><li>Forms over warm ocean water </li></ul></ul><ul><ul><li>Gains energy from warm water until it travels over land </li></ul></ul>
  8. 8. Vocabulary <ul><li>Tornado </li></ul><ul><ul><li>Column of spinning air </li></ul></ul><ul><ul><li>Forms over land </li></ul></ul><ul><ul><li>Warm, moist air encounters a mass of cold air </li></ul></ul><ul><li>Thunderstorm </li></ul><ul><ul><li>Electric rainstorm </li></ul></ul><ul><ul><li>Forms when a cold air mass runs into a warm air mass </li></ul></ul><ul><li>Drought </li></ul><ul><ul><li>Extended period of below-normal precipitation </li></ul></ul>
  9. 9. Content <ul><li>What is the Sun’s role in weather? </li></ul><ul><ul><li>Solar energy is responsible for all weather, all changes in weather </li></ul></ul><ul><ul><li>Solar energy heats Earth’s surface, evaporates water, and drives wind </li></ul></ul><ul><li>What is the ocean’s role in weather? </li></ul><ul><ul><li>Oceans are main source of water vapor for precipitation </li></ul></ul><ul><ul><li>Oceans moderate temperatures along coastlines </li></ul></ul><ul><li>Your questions? </li></ul>
