Weather Patterns Part 3
100
Temperature at which the air is saturated with water and condensation forms
What is the dew point?
100
Shows the weather conditions at one very specific location
What is a station model?
100
Conditions are right for severe weather to occur, it is not occurring yet, but it has a chance to occur
What is a sever weather watch?
100
The most powerful type of severe storm
What is a hurricane?
100
If dots represent air molecules, what can be concluded from the diagram below?
What is there are less air molecules at higher altitudes, resulting in lower air pressure.
OR
What is there are more air molecules at lower altitudes, resulting in higher air pressure
100
Which of the following is showing the necessary conditions for the precipitation of rain?
What is warm air and cloud droplets throughout the atmosphere...diagram A?
100
Type of air mass traveling south from Canada and is frigid
What is continental polar?
200
Use the graph to determine max water vapor at 5 degrees Celsius
What is about 0.4g/m3 to 0.5g/m3
200
Humidity (%), dew point 
,
type of precipitation 
What are symbols on a weather report map/station model?
200
What weather system is shown below?
What is a low pressure system?
200
Notification that severe weather is occurring in the area, take caution
What is a sever weather warning?
200
Current, short-term conditions of the atmosphere
What is the weather?
200
What type of front is this and what type of front is it?
This is a cold front, and it will bring intense/heavy precipitation and thunderstorms as the warm air mass is rapidly pushed upward and condenses
200
Air mass formed over the ocean near the equator
What is maritime tropical?
300
Measure of water vapor the air is holding compared to the amount needed for saturation at a specific temperature
What is relative humidity?
300
on a weather map, they connect equal points of temperature
What are isotherms?
300
What is in the forecast below?
What is a stationary front?
300
Type of severe weather that is not an intense tropic storm; forms from low pressure systems of continental air masses
What is a tornado?
300
Part of the water cycle that would be most noticeable on a summer day in an area under a low pressure system
What is part B, precipitation?
300
A boundary between cold and warm air masses
What is a front?
300
tracks areas of high and low pressure on a weather map using connected lines
What are isobars?
400
How fast the air masses are moving; units are in knots or mph; measured with an anemometer
What is wind speed?
400
Measured by human observation of the sky, shown on model as various levels of shading in the circle
What is cloud cover or sky conditions?
400
Hot and humid weather in Houston, TX during summer is most likely due to what type of air mass?
What is maritime tropical?
400
Produced during thunderstorms of continental air masses under low pressure; highly unpredictable in formation
What is a tornado?
400
typical weather for an area of low pressure
What is cloudy?
400
Type of air mass that produces heavy winter precipitation for Seattle, WA?
What is maritime polar?
500
Used to measure air pressure/barometric pressure
What is a barometer?
500
Why does high pressure mean good weather?
Air masses are sinking making it difficult for evaporation and condensation to occur, thus no clouds and no precipitation = no "weather"
500
Type of weather expected in open circle of diagram below
What is hot and dry/little rain in summer, but cool and rain in winter?
