Secular variation: Astronomy, Overview & Geomagnetic secular variation

The secular variation of a time series is its long-term, non-periodic variation (see Decomposition of time series). Whether a variation is perceived as secular or not depends on the available timescale: a variation that is secular over a timescale of centuries may be a segment of what is, over a timescale of millions of years, a periodic variation.…
