  2. weather basics Where does the energy for weather originate? the uneven heating of the Earth’s surface

  3. weather basics In the US, the general direction that weather systems move is toward the northeast

  4. Station Models Please go to page 13 of the ESRTs Temperature and dewpoint are measured in degrees _______ F

  5. Cloud Cover Temperature 76 138 Wind Direction & Speed .. -30\ Current Weather 55 Dewpoint Barometric Trend Barometric Pressure

  6. Station Model Practice

  7. Evaporation Rates Relative Humidity Temperature Surface Area

  8. What natural process cleans the atmosphere? Rain precipitation Snow Hail

  9. Cloud Formation

  10. Cools to the dewpoint Expands Warm Air Rises

  11. Clouds are likely to form when: The air is saturated and rising The temperature is at the dewpoint Condensation nuclei are available

  12. As air temperature increases the air can hold more water

  13. Sling Psychrometer Dry bulb measures air temperature Wet bulb temp is lower due to evaporation

  14. Using the charts on page 12 of the ESRTs, calculate the relative humidity and dew point using the following information. 60 6 15 12 58 7 55 23 13 9 5 Dewpoint Chart RH Chart

  15. Relative Humidity vs Air Temperature Indirect Relationship as temp increases RH decreases

  16. As dew point increases, the amount of moisture in the air INCREASES

  17. As temperature and dewpoint get closer together, the probability of precipitation INCREASES

  18. Which has the greatest probability of precipitation?
