Chapters 7-9 Review Flashcards
Lines of equal heat
Isotherms
Measures and transmits meteorological data
Radiosonde
The center of a hurricane
Eye
Forms when falling balls of ice are swept up into higher altitudes
Hail
Tornado that forms over water
Waterspout
Ratio of solar radiation reflected
Albedo
The outermost layer of the atmosphere
Exosphere
High level clouds that look like wispy streamers or feathers
Cirrus
when air expands with no heat gained or lost
Adiabatic cooling
Compares weather throughout the whole country at once
Surface weather chart
Produces heavy rains, strong winds and sometimes hail or tornados
Cumulonimbus
Convection cell between equator and latitude 30
Hadley cell
Comes from the top of thunderstorm
Positive cloud to ground lightning
Reflected light from high altitude strikes in distant thunderstorms
Heat lightning
Powerful radiation that heats the ionosphere
Cosmic rays
Measures the distance from the ground to the base of clouds
Ceilometer
The numbers and symbols on a weather map that indicate observations at a certain weather station
Station model
measures the amount of rainfall
Rain gauge
A single updraft system in a thunderstorm
Cell
Powerful computer used to generate weather forecast
Supercomputers
Air circulating as it rises and sinks
Convection current
Colorful displays from solar wind particles
Auroras
Change in wind direction from Earth’s rotation
Coriolis effect
warm, dry winds that go down mountain slope
Foehns
A major factor in weather
Water vapor
Surface winds that blow toad equator
Trade winds
movement of water from the earth to air, and back
Hydrologic cycle
The most destructive part of a hurricane
Wind
Cloud that is almond shaped
Lenticular
Heat by electromagnetic waves
Radiation
Measures wind speed
Anemometer
Is indicated by the start of precipitation
Mature stage
When water vapor touches the cool ground and turns into a liquid
Dew
Where the solar wind pushed on Earth’s magnetic field
Magnetopause
What atmospheric conditions limit how high rising air can travel
Stable
The farthest distance when objects can be distinguished
Visibility
A tropical cyclone with speeds from 39-74mph
Tropical storm
The most intense type of downburst
Microburst
A prediction of future weather
Forecast
Elevated water level caused by a hurricane
Storm surge
When the relative humidity is 100% the air is,
Saturated
Classifies tornadoes
Enhanced Fujita scale
Classifies hurricanes
Saffir-Simpson scale
The process of large water droplets hitting other water droplets and merging together
Collision-coalescence
A low pressure system without rotating winds
Tropical disturbance
A flexible, airtight metal box that measures atmospheric pressure
Aneroid barometer
The most abundant gas in the atmosphere
Nitrogen
The type of drought that affects the groundwater (Streams, lakes reservoirs)
Hydrological drought
A wind that reverses its direction from season to season
Monsoon
The downward stream of electrons that cause a single lightning bolt to make a second strike
Dart leader
What portion of a lightning bolt produces thunder
Return stroke
Indicates that a frontal cyclone has reached full strength
Formation of an occluded front
Radiation fog that is only 6ft above the ground
Shallow fog
Hot and dry weather
Continental tropical
The coldest point in the atmosphere
Mesopause
