Air pressure
the force exerted on a surface by the air above it as gravity pulls it to Earth.
Tropical
pertaining to, characteristic of, occurring in, or inhabiting the tropics, especially the humid tropics
Celsius
scale based on 0° for the freezing point of water and 100° for the boiling point of water
Cumulus cloud
are detached, individual, cauliflower-shaped clouds usually spotted in fair weather conditions
Cirrus cloud
a change in the weather is on the way
Thermometer
an instrument that measures temperature
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
Ocean Current
the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density
Dew Point
the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%
Hurricane
a storm with a violent wind, in particular a tropical cyclone in the Caribbean.
“a powerful hurricane hit the Florida coast”
Desert
an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year
Typhoon
a tropical cyclone with the maximum wind of 34 knots or higher
Humidity
the amount of water vapor in the air
Forecast
predict or estimate
Atmosphere
a mixture of gases that surrounds the Earth
Hail
precipitation in the form of small balls or lumps usually consisting of concentric layers of clear ice and compact snow
Thunderstorm
A rain-bearing cloud that also produces lightning
Cloud
a visible mass of particles of condensed vapor (such as water or ice) suspended in the atmosphere of a planet (such as the earth) or moon
Precipitation
any liquid or frozen water that forms in the atmosphere and falls back to the earth
Drought
a prolonged period of abnormally low rainfall, leading to a shortage of water
Front
a boundary between two air masses of different densities
Meteorology
the science dealing with the atmosphere and its phenomena, including both weather and climate
Freezing Point
the temperature at which a liquid becomes a solid at normal atmospheric pressure
Tornado
A violently rotating column of air touching the ground, usually attached to the base of a thunderstorm
Cumulonimbus Cloud
menacing looking multi-level clouds, extending high into the sky in towers or plumes
Thunder
the sound that follows a flash of lightning and is caused by sudden expansion of the air in the path of the electrical discharge
Weather
the state of the air and atmosphere at a particular time and place
Waterspout
a whirling column of air and water mist.
Barometer
a scientific instrument used to measure atmospheric pressure
Global Warming
a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants
Temperature
the degree of internal heat of a person’s body
Barometric Pressure
another term for atmospheric pressure
Funnel Cloud
a cone-shaped cloud which extends from the base of a cloud towards the ground without actually reaching the surface
Climate
the weather conditions prevailing in an area in general or over a long period
