  1. Now that you have your weather station built, we're going
  2. to collect weather data for a period of two weeks.
  3. You will need a detailed weather forecast using the weather
  4. data collected over a period of time from each backyard
  5. weather station, you need to put together a detailed weather
  6. forecast. This forecast could include the observed patterns in cloud
  7. shape, air temperature, wind direction, air pressure and precipitation.
  8. Also, did you observe any weather fronts as state park
  9. engineers? What is your final recommendation to the visitors coming
  10. to the park this weekend?
  11. Will it be pleasant or stormy?
  12. Will it be dangerous for the visitors?
  13. What precautions, if any, should visitors take, So you will
  14. need to provide some sort of presentation.
  15. You can choose how to prevent your forecast.
  16. Some ideas include a newspaper report, a poster showing the
  17. relevant weather features such as when direction, precipitation, cloud shape,
  18. presence of a weather front, etcetera.
  19. Or you could do a typical weather forecast in the
  20. form of a video using props for sun, rain clouds,
  21. warm fronts and cold fronts.
  22. This project is due on October 16th 2020.
  23. As you will need time to collect your data here
  24. is a possible extension.
  25. Should you want to further explore whether forecasting understanding the
  26. Doppler effect conduct the following demonstration to show how the
  27. Doppler effect works and how Doppler radar helps meteorologists predict
  28. the weather, you would need a battery operated razor or
  29. horn something with a steady tone cassette recorder with the
  30. microphone or some other device to record on.
  31. Record the sound of the razor or horn.
  32. Play the recording to make sure it sounds exactly like
  33. the original sound.
  34. Record the razor or horn again this time.
  35. Moved the razor or horn towards and past the microphone
  36. several times.
  37. Play the recording back and listen to the pitch of
  38. the razor or horn.
  39. Go up a zit, gets closer to the microphone and
  40. go down as it moves further away.
  41. Explanation. The change in the frequency of sound is called
  42. the Doppler Effect.
  43. Doppler radar measures the changes in the frequency of the
  44. signal it receives to detect the intensity of precipitation, estimate
  45. wind direction and speed and predict hail, size and rainfall
  46. amounts. Please make sure you contact me if you have
  47. any questions or need help with any of the assignments.
  48. I hope you enjoyed this weeks presentation, and I look
  49. forward to seeing you again next week
