100
This is a boundary between two air masses
What is a front?
100
These air masses originate over water
What are maritime air masses?
100
This is caused by the weight of the air above an area
What is air pressure?
100
The energy source that drives convection in Earth's atmosphere and hydrosphere is-
The sun
100
The H represents what on a weather map?
High pressure system
200
These occur when a warm air mass rises above a cold air mass gently
What are warm fronts?
200
These air masses originate over land
Continental
200
Air pressure does this with increasing height above Earth
What is decreases?
200
What three things work together to create weather and climate?
Sun, Atmosphere, Hydrosphere
200
Oklahoma is likely experiencing what type of weather?
Colder weather, likely with storms and clouds
300
These fronts are caused by a cold and warm air mass hitting head on, and the warm air mass rising rapidly into the atmosphere
What are cold fronts?
300
List the four combinations of air masses
Maritime Tropical
Maritime Polar
Continental Tropical
Continental Polar
300
This makes sunny clear skies with calm winds
What are high pressure systems?
300
How do ocean currents impact weather?
Currents circulate cold and warm water aorund the earth
300
What conditions are necessary for a tropical cyclone to form?
WARM OCEAN WATER AND LOW PRESSURE SYSTEM
400
These are represented by a purple colored front line on the weather map and have the alternating shapes on the same side of the line
What are occluded fronts?
400
This is a large body of air with relatively similar temperature and humidity
What are air masses?
400
This type of pressure system is caused when the warm air rises into the atmosphere leading to condensation
Low pressure system
400
How is wind formed?
Wind is formed when air moves from areas of high pressure to areas of low pressure
400
Why do cyclones weaken when they reach land?
Less water for condensation
500
These cause rain over several days
What are stationary fronts?
500
These are the part of the air mass names that depend on the temperature of the air mass
What are polar and tropical?
500
What is convection?
Warm air rises because it is less dense, once it is far enough away from the heat source the air cools and becomes more dense and sinks. The cycle continues
500
Texas is likely to experience what type of weather?
Cold weather
500
What are the three names for tropical cyclones and why are they named differently?
Cyclone
Hurricane
Typhoon
regional differences
