Flashcards in Weather Deck (27):
The definition of air pressure is the force exerted onto a surface by the weight of the air
the envelope of gases surrounding the earth or another planet.
an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
another term for atmospheric pressure.
the scale of temperature in which water freezes at 0° and boils at 100° under standard conditions.
the weather conditions prevailing in an area in general or over a long period.
a visible mass of condensed water vapor floating in the atmosphere, typically high above the ground.
is a dense towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents.
are puffy clouds that sometimes look like pieces of floating cotton.
the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
the atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form
a prolonged period of abnormally low rainfall; a shortage of water resulting from this.
the temperature at which a liquid turns into a solid when cooled.
a storm with a violent wind, in particular a tropical cyclone in the Caribbean.
a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena outside the tropics.
a rotating funnel-shaped cloud forming the core of a tornado or waterspout.
a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect
pellets of frozen rain that fall in showers from cumulonimbus clouds.
The study of weather
Rain hail sleet or snow
a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air.
a storm with thunder and lightning and typically also heavy rain or hail.
a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.
an atmospheric low-pressure system originating in the tropics
a tropical storm in the region of the Indian or western Pacific oceans.
