Tough Tide Question [5 pts]
This one is worth 5 points.
We all know that primarily the moon, and also sun and other planetary bodies, to a lessor extent cause the tidal variations. For semi-diurnal tides, there is a close correlation between the highest tide of the day with the following days tide (two highs later), and also a close correlation between the lessor tide that day with the lessor tide on the next day (also two tides later). While the tides that occur in the same day can have substantially different highs and lows. Given that the gravitational forces are close to the same relative position on a given day, one would think semi diurnal tides would be the same on a given day. Why do the tides sometimes vary more substantially during the same day compared with subsequent days? Bonus Question: When would you expect to see the greatest variation between same day tides? Explain what causes this effect. |
