Weather Terms Unit 2
| Question | Answer |
|---|---|
| weather | what the troposphere is like at any given time and place |
| climate | the average weather conditions for a specific part of the world |
| hydrological cycle | the continuous movement of water on Earth |
| condensation | water vapor turning into a liquid to create clouds |
| precipitation | any form of water particles (rain, snow, sleet, and hail) that falls from the atmosphere to the ground |
| evaporation | the changing of a liquid to a vapor due to heat |
| runoff | water flowing on the surface of the land and goes into rivers and streams |
| groundwater (infiltration) | water that soaks into the ground |
| transpiration | the loss of water through a plant's leaves into the atmosphere |
| air pressure | the force put on a given area by the weight of the air around it |
| tornado | a violent whirling wind that moves across the ground in a narrow path |
| hurricane | a very large, swirling storm; the lower the pressure the stronger the storm; center is called the eye; warm ocean water strengthens the storm |
| blizzard | storm with very low temperatures (<20 degrees Fahrenheit) and winds that are > 35 mph. Large amounts of snowfall decrease visibility. |
| thunderstorm | the most common severe storm, formed in cumulonimbus clouds |
| cirrus clouds | a high-altitude cloud made of ice crystals; thin and wispy |
| stratus clouds | a cloud that forms a blanket-like layer across the sky |
| cumulus | a puffy cloud that appears to rise up from a flat base; fair weather cloud |
| cumulonimbus clouds | large thunderstorm clouds; often called thunderheads |
| wind vane | a device that indicates wind direction |
| rain gauge | a cylinder tube that measures rainfall |
| anemometer | an instrument that measures wind speed |
| barometer | a device for measuring air pressure |
| thermometer | an instrument used to measure air temperature |
| hygrometer | a device used to measure humidity |
| ruler/yardstick | an instrument used to measure snowfall |
| humidity | the amount of water vapor in the air |
| global warming | average temperatures in Earth's atmosphere have increased over time |
| cold front | a boundary where cold air moves in under a mass of warm air |
| warm front | a boundary where warm air moves in over a mass of cold air |
| stationary front | an unmoving front where a cold air mass and a warm air mass meet |
| front | a boundary between two air masses with different temperatures |
| meteorologist | a person who studies weather |
| weather balloon | carries weather instruments high into the atmosphere to collect weather information |
| weather radar | a device used to locate precipitation, calculate its motion and intensity |
| weather satellite | a device that revolves around the Earth and detects and reports weather patterns on the Earth's surface |
| forecast | a prediction of what weather will be in the future |
| convection | the flow of energy caused by the movement of air |
| atmosphere | a blanket of gases that surrounds Earth |
| troposphere | the layer closest to Earth's surface; where most weather occurs |
| wind | air that moves horizontally |
| westerlies | winds in the US that typically blow from the WEST to the EAST |
| weather station | an observation post where weather data is observed and recorded |
| stratosphere | where the ozone layer is located; airplanes sometime travel here to avoid bad weather |
| thermosphere | the warmest layer, reaches over 2000 degrees Fahrenheit |
| mesosphere | the middle layer; meteors are seen here; coldest layer |
| exosphere | the highest layer of the atmosphere; extends to outer space |
| fall | If the Northern Hemisphere is experiencing spring, the Southern Hemisphere is experiencing ________. |
| winter | If the Northern Hemisphere is experiencing summer, the Southern Hemisphere is experiencing ________. |
| cold front | I am a fast moving front which brings heavy precipitation. |
| warm front | I am a slow moving front which brings light precipitation. |
| precipitation | All fronts (warm, cold, and stationary) bring _______________ to an area. |
| cold front | shown on a weather map using a blue line with triangles |
| warm front | shown on a weather map using a red line with semicircles |
| Storms, such as hurricanes and tornadoes, have centers with what kind of pressure? | LOW pressure |
