nocturnal If something is nocturnal, it belongs to or is active at night. That includes vampires, owls that like to hunt by moonlight, and that roommate who stays up playing video games until the wee hours of the morning.

Diurnal cycle A diurnal cycle is any pattern that recurs every 24 hours as a result of one full rotation of the Earth with respect to the Sun.In climatology, the diurnal cycle is one of the most basic forms of climate patterns. The most familiar such pattern is the diurnal temperature variation.Such a cycle may be approximately sinusoidal, or include components of a truncated sinusoid (due to the sun's rising and setting) and thermal relaxation (Newton cooling) at night. diurnal cycle is any pattern that recurs every 24 hours as a result of one full rotation of the Earth with respect to the Sun.

If the circadian component of diurnal PA variation is reduced in depression, the normative quadratic waveform of diurnal PA variation might be supplanted by alternative patterns, such as a linear increase across the waking day.

Diurnal pressure variation Diurnal pressure variation. Measurements of surface pressure reveal a both a diurnal and a semidiurnal (12h) rhythm underlying any longer-term (synoptic) variation (1). This rhythm is the surface image of a diurnal tide of the entire atmosphere. A wave moves across the upper atmosphere, westward with the speed of the Sun.
