    1. 1. 11.3 Moisture in the atmosphere Pages 285 - 291
    2. 2. Goal 1 Explain how clouds are formed
    3. 3. <ul><li>Three basic steps </li></ul><ul><ul><li>1. Air mass rises </li></ul></ul><ul><ul><li>2. Air mass cools and expands </li></ul></ul><ul><ul><li>3. LCL reached for condensation to form clouds </li></ul></ul>
    4. 4. <ul><li>Step 1 </li></ul><ul><ul><li>Air mass rises by the following mechanisms </li></ul></ul><ul><ul><ul><li>Convection current </li></ul></ul></ul><ul><ul><ul><li>Orographic lifting </li></ul></ul></ul><ul><ul><ul><li>Different temperature air mass collision </li></ul></ul></ul>
    5. 5. <ul><li>Air mass rising by convection </li></ul><ul><ul><li>Air mass warms up </li></ul></ul><ul><ul><li>Air mass flows up in atmosphere </li></ul></ul><ul><ul><li>Clouds form when LCL reached </li></ul></ul>
    6. 6. <ul><li>Air mass rising by orographic lifting </li></ul><ul><ul><li>Air mass forced up mountainside </li></ul></ul><ul><ul><li>Cloud forms when LCL reached </li></ul></ul>
    7. 8. Air mass rising by collision <ul><li>Air mass rising by collision </li></ul><ul><ul><li>Cold air mass collides with warm air mass </li></ul></ul><ul><ul><li>Warm air mass forced up </li></ul></ul><ul><ul><li>Cloud forms when LCL reached </li></ul></ul>
    8. 9. <ul><li>Step 2 </li></ul><ul><ul><li>Air mass expands and cools </li></ul></ul><ul><ul><li>Lower pressure at higher altitudes allow air mass to expand / spread out </li></ul></ul>
    9. 10. <ul><li>Step 3 </li></ul><ul><ul><li>LCL reached (dew point temp of cloud) </li></ul></ul><ul><ul><li>Condensation occurs around condensation nuclei </li></ul></ul><ul><ul><li>Voila! A cloud! </li></ul></ul>
    10. 11. <ul><li>Stability </li></ul><ul><ul><li>Air mass resistance to rising </li></ul></ul><ul><ul><ul><li>Cold surface </li></ul></ul></ul><ul><ul><ul><li>Warm neighboring air masses </li></ul></ul></ul>
    11. 12. <ul><li>Latent heat </li></ul><ul><ul><li>Energy released from condensation </li></ul></ul><ul><ul><li>Provides energy to storm system </li></ul></ul><ul><ul><ul><li>Warms air mass more </li></ul></ul></ul><ul><ul><ul><li>More rising </li></ul></ul></ul><ul><ul><ul><li>More condensation </li></ul></ul></ul><ul><ul><ul><li>More warming </li></ul></ul></ul><ul><ul><ul><li>Etc…. </li></ul></ul></ul>
