Air pressure
Atmospheric pressure, sometimes also called barometric pressure, is the pressure exerted by the weight of air in the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.
atmosphere
the envelope of gases surrounding the earth or another planet.
barometer
an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
barometric pressure
Atmospheric pressure, sometimes also called barometric pressure, is the pressure exerted by the weight of air in the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.
Celsius
Celsius, also known as centigrade, is a metric scale and unit of measurement for temperature. As an SI derived unit, it is used by most countries in the world.
climate
the weather conditions prevailing in an area in general or over a long period.
cumulonimbus cloud
Cumulonimbus, from the Latin cumulus and nimbus, is a dense towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents.
cumulus cloud
Cumulo- means “heap” or “pile” in Latin. Cumulus clouds are often described as “puffy”, “cotton-like” or “fluffy” in appearance, and have flat bases.
dew point
the atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form.
drought
a prolonged period of abnormally low rainfall; a shortage of water resulting from this.
Losses or destruction of fish and wildlife habitat.
Lack of food and drinking water for wild animals.
Increase in disease in wild animals, because of reduced food and water supplies.
Migration of wildlife.
Increased stress on endangered species or even extinction.
freezing point
the temperature at which a liquid turns into a solid when cooled.
hurricane
a storm with a violent wind, in particular a tropical cyclone in the Caribbean.
a wind of force 12 on the Beaufort scale (equal to or exceeding 64 knots or 74 mph).
front
A weather (state of atmosphere) front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena outside the tropics. In surface weather analyses, fronts are depicted using various colored triangles and half-circles, depending on the type of front
funnel cloud
a rotating funnel-shaped cloud forming the core of a tornado or waterspout.
global warming
Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate.
hail
pellets of frozen rain that fall in showers from cumulonimbus clouds.
meteorology
The science that deals with the phenomena of the atmosphere, especially weather and weather conditions. [French météorologie, from Greek meteōrologiā, discussion of astronomical phenomena : meteōron, astronomical phenomenon; see meteor + -logiā, -logy.] me′te. · or.
precipitation
rain, snow, sleet, or hail that falls to the ground.
thunder
a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air.
thunderstorm
a storm with thunder and lightning and typically also heavy rain or hail.
tornado
a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.
tropical depression
A tropical depression forms when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph. An upgrade to a tropical storm occurs when cyclonic circulation becomes more organized and maximum sustained winds gust between 39 mph and 73 mph.
typhoon
a tropical storm in the region of the Indian or western Pacific oceans. And A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.
weather
the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
Humidity
a quantity representing the amount of water vapor in the atmosphere or a gas.
Cloud
a visible mass of condensed water vapor floating in the atmosphere, typically high above the ground.
