Weather Maps
This weather front has blue arrows pointing in the direction of air movement.
What is a cold front?
This type of pressure is denoted as a "H" on a weather map.
What is high pressure?
This is the instrument that measures temperature.
What is a thermometer?
Most severe weather is caused by this type of front.
What is a cold front?
This fluffy, cotton-like cloud has been nicknamed the "fair weather cloud".
What are cumulus clouds?
This weather front has red semi-circles that move in the direction of the circles.
What is a warm front?
This type of pressure is denoted as a "L" on a weather map.
What is low pressure?
This is the direction wind can be measured flowing in: from one pressure to the other.
What is from high pressure to low pressure?
Cold air and objects cause this phenomenon, in which water collects into droplets onto condensation nuclei.
What is condensation?
These are the two ingredients that clouds are made of.
What are ice crystals and water droplets?
This weather front has alternating red semi-circles and blue triangles and does not move.
What is a stationary front?
This type of pressure is associated with clear weather.
What is high pressure?
These instruments measure the humidity in the air.
What are hygrometers or (sling) psychrometers?
Warm air rises and cools to form these floating objects through condensation of humidity.
What are clouds?
This type of cloud is produced when strong cold fronts move through an area to produce powerful storms.
What are cumulonimbus clouds?
This weather front has purple triangles and semi-circles and three fronts involved.
What is an occluded front?
This type of pressure is associated with storms, such as thunderstorms and hurricanes.
What is low pressure?
This instrument measures atmospheric or barometric pressure.
What is a barometer?
This effect causes points of higher elevation to produce more ice.
What is a decrease in temperature with elevation?
This type of cloud is associated with snow and long-lasting rain.
What are stratus?
These are lines of equal atmospheric pressure.
What are isobars?
Wind always flows from this pressure to the other pressure.
Where is from high pressure to low pressure?
This is the instrument that measures wind speed.
What is an anemometer?
This effect produces rotation effects on large storms; the spin is different north and south of the Equator.
What is the Coriolis Effect?
This type of cloud is associated with heavy rain, hail, thunderstorms, and tornadoes.
What is a cumulonimbus cloud?
