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 and is associated with clear weather.
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?
Warm air rises and cools to form these floating objects through condensation of humidity.
What are clouds?
As air flows over bodies of warm water and picks up moisture, this effect occurs over land.
What is precipitation?
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 and is associated with storms and hurricanes.
What is low pressure?
This weather instrument measures the direction the wind is flowing in.
What is the weather vane?
This is the direction that station model wind barbs point.
What is the direction that the wind is coming from?
This type of cloud is produced when strong cold fronts move through an area to produce powerful storms.
What are cumulonimbus clouds?
This is how the volcano Mt. Pinatubo caused climate change with sulfur dioxide and ash when it erupted.
What is the particles decreased solar radiation reaching the surface?
This weather front has alternating red semi-circles and blue triangles and does not move.
What is a stationary front?
Wind always flows from this pressure to the other pressure.
What is from high to low pressure?
These instruments measure the humidity in the air.
What are hygrometers or (sling) psychrometers?
Cold air and objects cause this effect, in which water vapor collects into droplets onto condensation nuclei.
What is condensation?
This type of cloud is associated with snow and long-lasting rain.
What are stratus?
Carbon dioxide has increased in the atmosphere due to this.
What is the increase in burning fossil fuels?
This weather front has purple triangles and semi-circles and three fronts involved.
What is an occluded front?
A low pressure system (hurricane) has left the equator. What happens when the system reaches the cooler waters of 60°N?
What is that it has lost most of its energy?
This instrument measures air, or atmospheric, pressure.
What is a barometer?
This process of rising warm air and sinking cold air is a major cause of weather.
What is "convection"?
Warm air must do these steps to form clouds.
What are rise, cool, and condense water vapor?
This is how carbon dioxide and atmospheric temperatures have recently changed, as shown in the graph.
What is an increase in both carbon dioxide levels and atmospheric temperatures?
These are lines of equal atmospheric pressure.
What are isobars?
On a station model, pressure must be converted from the provided number. Identify the converted pressures for 347 and 671.
What are 1034.7 and 967.1?
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?
These particles of ash or dust are required for water to condense into clouds.
What are "condensation nuclei"?
This is why the amount of oxygen has increased in Earth's atmosphere.
What are photosynthetic algae and plants?
