Weather~May Flashcards
Air Pressure
the force that air puts on an area
Tropical
describing a climate that is very hot and humid; describing an area of Earth that is near the equator
Celsius
the metric temperature scale
Cumulus Cloud
large, fluffy, white clouds, often seen in fair skies
Cirrus Cloud
thin, wispy-looking clouds;
Thermometer
a devices used to measure temperature
Tropical Depression
a region of low pressure with counter-clockwise wind rotation that develops into a hurricane or tropical storm
Ocean Current
large-scale movement of water within the oceans in a certain direction
Dew Point
the temperature at which water vapor in the air condenses into water
Hurricane
a storm with strong winds and rain that forms over tropical waters
Desert
an area that gets little precipitation and has very little vegetation
Typhoon
a hurricane or tropical storm originating in the Pacific Ocean
Humidity
the measure of how much water vapor is in the air
Forecast
to analyze weather data and make an educated guess about weather in the future
Atmosphere
the layers of gases that surround a planet
Hail
small, icy balls that fall from the sky
Thunderstorm
a weather system that produces heavy precipitation, winds, lightning, and thunder
Cloud
a collection of water droplets or ice crystals in the atmosphere
Precipitation
water that is released from clouds in the sky; includes rain, snow, sleet, hail, and freezing rain
drought
a prolonged shortage of rainfall
front
in weather, the boundary between two masses of air with different properties
Meteorology
the study of patterns of weather
freezing point
the temperature at which a liquid turns into a solid
Tornado
a funnel-shaped cloud or column of air that rotates at high speeds and extends downward from a cloud to the ground
Cumulonimbus Cloud
anvil-shaped cloud that is often involved in heavy or violent storms: Cumulonimbus clouds are also called thunderheads
Thunder
a loud noise that happens when lightning heats the air and causes it to expand and contract quickly
Weather
the properties of the atmosphere at a given time and location, including temperature, air movement and precipitation
Waterspout
a funnel-shaped cloud that forms over water and pulls water upward
Barometer
a tool used to measure air pressure
Global Warming
the slow warming of Earth’s atmosphere due to climatic change
Temperature
a measure of the average kinetic energy of the atoms in a system, used to express thermal energy in degrees
Barometric Pressure
the pressure (force per unit area) of the atmosphere against a surface
Funnel Cloud
a rotating, funnel-shaped cloud
Climate
the average weather conditions in an area
