- the maximum parallax observed when the celestial body is at the horizon
- blizzard
- a storm with widespread snowfall accompanied by strong winds
- El Nino
- (oceanography) a warm ocean current that flows along the equator from the date line and south off the coast of Ecuador at Christmas time
- daylight
- light during the daytime
- magnetosphere
- the magnetic field of a planet; the volume around the planet in which charged particles are subject more to the planet's magnetic field than to the solar magnetic field
- antitrade wind
- winds blowing from west to east and lying above the trade winds in the tropics
- cell death
- (physiology) the normal degeneration and death of living cells (as in various epithelial cells)
- transparence
