Weather Terms
The transfer of heat through space or matter by waves
What is Radiation
An instrument used by measure wind speed by a meteorologist
What is an anemometer?
Visible collections of tiny water droplets or ice crystals in the atmosphere which combine
What are clouds
Winds that blow 30 degrees latitude to the equator
What are Trade Winds?
Sound that results from the rapid expansion of air that accompanies a lightning strike
What is Thunder?
The transfer of heat from one substance to another through direct contact
What is Conduction?
instruments used for measure change in temperature
What is a thermometer
puffy, white, low-level clouds. Means, "lumpy."
What are Cumulus clouds
The movement of air from an area of high pressure to low pressure
What is Wind?
Lines drawn between areas of equal atmospheric pressure also shown on surface maps. Appear as odd-shaped ovals or circles showing areas of low and high pressure.
What are Isobars
The transfer of heat from moving fluids (gasses and liquids).
What is Convection
An instrument used to measure atmospheric pressure
What is a barometer
thin, feathery, high-level clouds. Means, "lock of water."
What are cirrus clouds?
Condensed water vapor near the ground forms in several ways at different levels.
What is Fog?
Farmers growing shelterbelts of trees in order to divert the wind
What is small control of the weather
Pressure exerted by the Earth's atmosphere at any given point. Varies from place to place
What is Atmospheric Pressure
An instrument used to measure altitude
What is an altimeter
stretched out in layers across the sky. Means, "layered."
What are stratus clouds
The amount of water in the air. It increases as more water molecules evaporate into the air
What is Humidity?
Large, rotating tropical weather systems with wind speeds of at least 119 km per hour. Packing more power than hundreds of thunderstorms
What are hurricanes?
The curving of moving objects from a straight path due to the Earth's rotation
What is Coriolis Effect
An instrument used to track storms with concentrated electric pulses that shoot forward
What is Radar?
Means, "rain cloud."
What are nimbus clouds
Boundary between air masses. Usually what makes the weather change
What is a Front?
Clouds are showered with crystals of dry ice allowing rain droplets to form. These tiny crystals attract water molecules which eventually grow large enough to form rain or snow
What is Cloud Seeding
