Which weather pattern has the most influence on weather in NC?
Prevailing westerlies move weather from west to east across the US
What does a cold front looks like on a weather map?
blue triangles
Puffy, white clouds
Cumulus Clouds
An instrument to record the amount of rainfall at a given area
Rain gauge
The best place to be during a tornado warning
Basement or lowest level bathroom/closet, no windows
What affects the coast of North Carolina causing it to receive less snow than the rest of the state during the winter?
The Gulf Stream
What type of weather do you experience with a warm front?
warmer temperatures, rain
Tall cumulus clouds that bring thunderstorms
Cumulonimbus clouds
An instrument that measures air pressure
Barometer
A tornado that forms over water
Waterspout
If you lived in the Southern Hemisphere what season would you likely experience in August?
Winter
When two air masses meet and DO NOT MOVE for a long time, bringing about long periods of precipitation
stationary front
Thin, wispy clouds made of ice crystals
Cirrus clouds
An instrument that measures wind speed
Explain the difference between a funnel cloud and a tornado
A funnel cloud is when you have rotation extending from a storm or cloud base.
When that rotation extends to and reaches the ground, it is considered a tornado.
In winter, if there's a dip in the jet stream over the east coast, what weather condition would the east coast experience?

Describe why the winds at the beach change direction from day to night.
Double Points: Describe land breeze and sea breeze (which way do the winds blow? day or night? what's cooler land or sea?)
Because the temperature over land and water change, causing the wind to change direction.
Land breeze- from land to sea, happens at night
Sea breeze- from sea to land, happens during day
What happens when two air masses (cold air and warm air) meet?
The cold air will sink and the warm air will rise over the cold air.
Puffy white clouds that are located high in the sky
Altocumulus clouds
A small instrument package that is suspended below a weather balloon and measures pressure, temperature, and relative humidity
Radiosonde
The name of the scale used to rate the intensity of a tornado
Enhanced Fujita Scale (half points for EF scale)
