diurnal
Examples of diurnal in the following topics:
-
Introduction to the Fourier Series
- So buried in the time-series on the top you would expect to see two dominant frequencies, one that was diurnal (1 cycle per day) and one that was semi-diurnal (2 cycles per day).
- You'll notice in the tiltmeter spectrum that the two peaks (diurnal and semi-diurnal seem to be split; i.e., there are actually two peaks centered on 1 cycle/day and two peaks centered on 2 cycles/day.
- Given what we know about the physics of tilt, we should expect that the diurnal tide (once per day) should peak at 1 cycle per day, while the semi-diurnal tide (twice per day) should peak at 2 cycles per day.

Tides
- Shorelines where two almost equally high tides and two low tides occur each day experience a semi-diurnal tide.
- The occurrence of only one high and one low tide each day is known as diurnal tide.
