Weather Vocab Flashcards
Air pressure
The force exerted by air
Tropical
very hot and humid:
a tropical climate.
Celsius
Thermodynamics. of or relating to a temperature scale having the same units as the Celsius scale but in which the zero point has been shifted so that the triple point of water has the exact value 0.01°; Celsius temperatures are computed from Kelvin values by subtracting 273.15 from the latter
Cumulus Cloud
Large, white, puffy clouds that generally appear during fair weather, although they also form thunderheads on hot days. Some carry rain.
Cirrus cloud
Lacy or wispy clouds that form at high altitudes, generally before a change in the weather.
Thermometer
an instrument for measuring temperature, often a sealed glass tube that contains a column of liquid, as mercury, that expands and contracts, or rises and falls, with temperature changes, the temperature being read where the top of the column coincides with a calibrated scale marked on the tube or its frame.
tropical depression
an atmospheric low-pressure system originating in the tropics, specifically, a tropical cyclone in which the maximum sustained wind speed is 38 miles per hour (62 kilometers per hour) or less.
Ocean current
a flowing; flow, as of a river.
something that flows, as a stream.
Dew point
the temperature to which air must be cooled, at a given pressure and water-vapor content, for it to reach saturation; the temperature at which dew begins to form.
Hurricane
Meteorology. a tropical cyclone of the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, or eastern Pacific Ocean, having sustained wind speeds of at least 64 knots (74 miles per hour, 33 meters per second): hurricanes form in waters with surface temperatures of about 80°F (27°C), intensifying as temperatures rise.Compare typhoon
Desert
a region so arid because of little rainfall that it supports only sparse and widely spaced vegetation or no vegetation at all
Typhoon
Meteorology. a tropical cyclone in the western Pacific Ocean or northern Indian Ocean, having sustained winds of at least 64 knots (74 miles per hour, 33 meters per second): typhoons form in waters with surface temperatures of about 80°F (27°C), intensifying as temperatures rise.Compare hurricane
Humidity
humid condition; moistness; dampness.
relative humidity.
an uncomfortably high amount of relative humidity:
Forecast
to predict (a future condition or occurrence); calculate in advance: to forecast a heavy snowfall; to forecast lower interest rates.
Atmosphere
the gaseous envelope surrounding the earth; the air
