A thermometric scale on which 32Â° denotes the freezing point and 212Â° the boiling point of water, both under standard atmospheric pressure.
FAHRENHEIT TEMPERATURE SCALE
A temperature scale where water at sea level has a freezing point of +32Â°F and a boiling point of +212Â°F. More commonly used in areas that observe the English system of measurement. Created in 1714 by Gabriel Daniel Fahrenheit (1696-1736), a German physicist, who also invented the alcohol and mercury thermometers.
This is a subjective description. Considered as pleasant weather conditions with regard to the time of year and the physical location.
With respect to weather, generally descriptive of pleasant weather conditions, with regard to location and time of year.
The area in which ocean waves are generated by the wind. It is generally delineated by coast lines, fronts, or areas of wind curvature or divergence.
A bright eruption from the sun's chromosphere (outer layers). Flares may appear within minutes and fade within an hour. They cover a wide range of intensity and size, and they tend to occur between sunspots or over their penumbrae. Also called solar flare.
Flooding caused by a rapid rise in the water level of rivers, streams, or lakes, usually as a result of heavy rains.
A warm, dry wind on the lee side of a mountain range, the warmth and dryness of air being due to adiabatic compression upon descending the mountain slopes.
A cloud of water droplets suspended in the air that touches the ground; also described as a cloud at the earth's surface.
Moisture that is deposited on terrestrial objects by fog and then falls to the ground.
The change in substance from a liquid to a solid state.
Particles suspended in the air around which ice crystals form.
Supercooled drops of water that turn to ice when they hit a cold surface.
The boundary between two different air masses.
The term used to describe the process which creates a front i.e., produces discontinuity in a continuous field of the meteorological elements; also applied to the process which increases the intensity of a pre-existing front. Frontogenesisis generally set up by the horizontal convergence of air currents possessing widely differing properties.
Ice crystals that form on grass and other objects when the temperature and dew point fall below freezing.
A fog produced by apparent steaming of the sea in the presence of air having a temperature much below freezing. Also called Arctic sea smoke .
A scale for estimating damage caused by the winds of tornado, developed by Theodore Fujita.
Interaction of two tropical cyclones. In general, two tropical cyclones may start to affect each other when the distance between them is around 12 latitude degrees (about 1350 kilometers). When this occurs, The tropical cyclones will rotate around one another in a counter-clockwise direction (in Northern Hemisphere) about their geometric centre. The centre needs not be the middle of the axis. The stronger cyclone tends to have a dominant effect on the track of the weaker one. The interaction will end when: there is a stronger influence of a large scale weather system from outside, one of the tropical cyclones weakens or the two cyclones merge.
