Nouns denoting natural phenomena
- sunrise
- atmospheric phenomena accompanying the daily appearance of the sun
- meteor
- a streak of light in the sky at night that results when a meteoroid hits the earth's atmosphere and air friction causes the meteoroid to melt or vaporize or explode
- ferromagnetism
- phenomenon exhibited by materials like iron (nickel or cobalt) that become magnetized in a magnetic field and retain their magnetism when the field is removed
- nonlinear distortion
- distortion that occurs when the output signal does not have a linear relation to the input signal
- centripetal force
- the inward force on a body moving in a curved path around another body
- microwave
- a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data
- gale
- a strong wind moving 45-90 knots; force 7 to 10 on Beaufort scale
- glow
- the phenomenon of light emission by a body as its temperature is raised
- infrared spectrum
- the spectrum of infrared radiation
- pyroelectricity
- generation of an electric charge on certain crystals (such as tourmaline) as a result of a change in temperature
- atmospheric electricity
- electrical discharges in the atmosphere
- phosphorescence
- a fluorescence that persists after the bombarding radiation has ceased
- load
- the power output of a generator or power plant
- magnetic field
- the lines of force surrounding a permanent magnet or a moving charged particle
- vapor pressure
- the pressure exerted by a vapor; often understood to mean saturated vapor pressure (the vapor pressure of a vapor in contact with its liquid form)
- Saint Elmo's light
- an electrical discharge accompanied by ionization of surrounding atmosphere
- IOP
- pressure exerted by the fluids inside the eyeball; regulated by resistance to the outward flow of aqueous humor
- hurricane
- a severe tropical cyclone usually with heavy rains and winds moving at 63-136 knots (12 on the Beaufort scale)
- bioluminescence
- luminescence produced by physiological processes (as in the firefly)
- magnetic moment
- the torque exerted on a magnet or dipole when it is placed in a magnetic field
