Lab 6.4 – Investigating Other Wave Events

Estimated time to complete: 30 minutes
Materials needed: none

In Labs 6.1 and 6.2 you saw that local atmospheric conditions can change quickly and this can lead to rapid changes in wave height. Here your objective is to examine data over a 1-month time period to investigate how/when wave height is related to local atmospheric conditions.

Atmospheric Pressure and Wind Speed

Insert Widget #1

  1. Do you see the same relationships between atmospheric pressure and wind speed that you saw from the single storm event in the first labs?
  2. Based on changes in atmospheric pressure and wind speed from the graph, identify three time periods when you would expect to see larger wave height.
  3. When do you expect to see the largest wave height in the month of February?

Wave Height and Wind Speed

Insert Widget #2

  1. Compare the measured wave height to the three time periods you predicted would be greatest. How do they agree/disagree with your predictions?
  2. Was your prediction of when the largest wave height would occur correct?
  3. If there are time periods with large wave height that you did not predict, what do you think caused those waves? Where do you think they were generated?
