Chronopedia
advancing
-
(phase shift) Shortening of period for one to a few cycles (sign +).
alpha-α
-
Activity time.
amplitude
-
Difference between maximum (or minimum) and mean value of the rhythmic parameter studied.
annual
- (Cycle) Event(s) occurring on a yearly basis. Used synonymously with "seasonal cycle"
arophase
- Phase angle corresponding to the maximal value of the rhythmic parameter studied.
circa
- (Rhythm) Internal rhythm, free running in constant conditions with a period slightly deviating from the environmental cycle, by which it is synchronized in nature (in contrast to non circa-rhythm).
circa-syzygic
- See circa-semilunar.
circadian
- Circa-rhythm with a naturally synchronized period of 24 hours.
circalunadian
- Circa-rhythm with a naturally synchronized period of 24.8 h (sidereal day or lunar day).
circalunar
- Circa-rhythm with a naturally synchronized period of the lunar cycle (either synodic cycle 29.53 days, or sidereal cycle 13.66 days).
circannual
- Circa-rhythm with a naturally synchronized period of a year.
circasemilunar
- Circa-rhythm with a naturally synchronized period of half the lunar cycle (semi-synodic or syzygic cycle: 14.76 days; semi-sidereal cycle 13.66 days).
circatidal
- Circa-rhythm with a naturally synchronized period of the prevailing tidal cycle (12.4 h or otherwise).
clock
- Timing mechanism, in which the parameter studied, is not involved in the causal loop (in contrast to "hourglass").
crepuscular
- Events occurring twice a day, i.e. at dawn and dusk.
