What is H and L?

 These are the symbols used to show a high pressure system and a low pressure system on a weather map.

100
This is the boundary between two air masses.
What is a front?
100
This technology is used to collect data from high in the atmosphere, even up to the stratosphere. The negative part of this technology is that it must be constantly replaced.
What is a weather balloon?
100
This is what we call a large region of the atmosphere in which the air has similar properties throughout.
What is an air mass?
100
These lines connect places with equal air pressure.
What are isobars?
200

This is the type of weather found in a low pressure system.

What are clouds, precipitation, and maybe severe weather like thunderstorms, tornadoes, and hurricanes?

200
In this type of front, cold air moves in under a warm air mass.
What is a cold front?
200
This technology sends photos from space back to earth and shows large weather patterns.
What is a satellite?
200
This is the direction that colder air moves.
What is down (or coolder air sinks)?
200
This is the unit used to measure air pressure.
What is the millibar?
300
This type of weather is found in a high pressure system.
What is clear skies, with little or no clouds?
300
In this type of front, cool air catches up with a warm front and then moves underneath the warm front, creating a wedge of warm air between two masses of cooler air.
What is an occluded front?
300
This technology is used to show both precipitation and wind speed.
What is Doppler radar?
300
When comparing warmer and cooler air, this one can hold more humidity.
What is warmer air?
300
This is when air moves from an area of high pressure to an area of low pressure.
What is wind?
400
This is the direction warm air moves.
What is up (warm air rises)?
400
This type of front usually brings light but steady precipitation. Afterward, the weather is usually warmer and more humid.
What is a warm front?
400
This instrument is used to measure air pressure.
What is a barometer?
400
When comparing warmer and cooler air, this one has lower air pressure.
What is warmer air?
400
This is what we would expect winds to be like in an area where isobars are widely spaced apart.
What is...no wind or just a gentle breeze?
500
Cooler air has this type of air pressure when compared to warmer air.
What is higher air pressure?
500
This type of weather usually comes with a cold front (tell two specific possibilities)
What is brief but heavy storms, a drop in temperature, after the front passes the weather is clearer with cooler temperatures and lower humidity?
500
This is an effect that technology has had on weather forecasting.
What is...-forecasts are more accurate? -forecasts can be made further in advance?
500
These are two properties of an air mass.
What are temperature, humidity, and/or air pressure?
500
This is the direction most weather in the US usually travels. AND It travels this way because of this global wind.
What is west to east? the westerlies?
