Air Masses
Name the 4 types of fronts.
What are warm, cold, stationary, and occluded.
What is an isobar?
On weather maps and connect areas of equal pressure.
From west to east
What does a blue H on a weather map represent? What type of weather will it bring?
A high pressure area. It means cool, dry, calm weather
This type of front is formed when a fast moving cold air mass meets a slow moving warm air mass.
Cold Front
What is an isotherm?
On weather maps and connect areas of equal temperature.
Where are the strongest winds located in the jet stream?
In the center
How is a stationary front represented on a weather map?
Alternating blue triangles and red circles.
What is a sea breeze?
Happens when the land heats up faster than the water which means the air over the land is warmer and less dense than the air over the water.
Since the air is less dense it rises, then the colder more dense air from the water replaces it and causes an onshore breeze.
How is an occluded front represented on a weather map?
Purple line with half circles on it.
What is a land breeze?
Happens at night when the water heats up faster than the land, which means the air over the water is warmer and less dense than the air over the land.
When this is in place the warmer less dense air over the water rises and the colder less dense air replaces it.
What is the wind direction and speed of the weather station model Mrs. Brown has drawn on the board?
Northeast, wind speed it 35 knots
The shapes on the front line point in the direction of movement.
How do convection currents in the ocean and atmosphere affect weather conditions around the world?
Water/air is heated at the equator, it then rises to the poles where it is cooled and them drops back down to the equator. This movement creates convection currents that affect our wind, ocean currents and weather around the world.
What does a red L on a weather map represent? What type of weather will it bring?
Low pressure system. Warm, moist, cloudy, unstable weather.
