Station Models
The circle in the middle of a station model is used to show this.
What is cloud cover?
This diagram represents the current weather conditions at a given weather station.
What is a station model?
This is the boundary between two air masses.
What is a front?
This type of front has triangles and half-circles on opposite sides of a line that is both red and blue.
What is a stationary front?
This type of heat transfer is how the Earth warms up from the Sun's rays.
What is radiation?
The number to the upper left of the center circle on a station model show this.
What is the temperature?
The line drawn on the center circle of a station model represents this.
What is the wind direction?
This type of front is represented on a map with blue lines and triangles.
What is a cold front?
This type of front is the slowest moving.
What is a stationary front?
This type of heat transfer happens in our atmosphere, but is also responsible for the movement of plates in the earths crust and molten material in the mantle.
What is convection?
The number to the lower left of the center circle on a station model represents this.
What is the dew point?
The upper boundary of the mesosphere and has an average temperature of nearly -130 ˚C.
What is mesopause
This type of front is represented on a weather map by red lines and half-circles.
What is a cold front?
What is an occluded front?
The warming of the surface and lower atmosphere of Earth that occurs when carbon dioxide, water vapor, and other gases in the air absorb and reradiate infrared radiation. Without this the Earth would be very cold.
What is greenhouse effect
What are fair skies or sunny?
If the first number on the pressure digits of a station model was a 7, which number would we put a 9 or a 10 in front of it to represent the actual pressure?
What is a 9?
This type of front has warm air pushing up over slower moving cold air. This type of front will often have cirrus clouds that precede it by a day or two.
What is a warm front?
This type of front occurs when a cold air mass overruns a warm air mass that is running into another cold air mass. Three different air masses are present at the same time.
What is an occluded front?
Air closest to the Earth warms by direct contact with the ground. What type of heat transfer is being described?
What is conduction?
The number to the upper right of the central circle is incomplete. One of two numbers (and a decimal point) must be added. What are the two numbers?
What is 9 or 10?
How would we describe the humidity level if the two numbers on the left side of the center circle on a station model were far apart?
What is dry?
This is how we tell which direction a front is moving.
In an occluded front, the warm air mass gets pushed up in between the two colder air masses. This type of cloud typically forms in this area which can lead to strong storms.
What are cumulonimbus clouds?
Air that gets warmed at the surface of the Earth rises and colder air aloft sinks. The circulation of the air in the atmosphere demonstrates what type of heat transfter?
What is convection?
