Air Pressure/ Pressure Systems
Determining wind direction - winds blow from this type of pressure to this type of pressure
What is high to low pressure?
Fronts can be defined as
what is the leading edge of a air mass?
Measures temperature
What is a thermometer?
Where do most of the air masses that are cold and dry come from?
What is Canada and the Continential Polar?
The higher up a mountain you go what happens to the temperature?
What is the higher the altitude the cooler the climate?
Isobars can be define as
What are lines that connect areas of the same pressure?
Cold fronts bring in the following conditions: temp, precipitation
What is cold temps and storms?
Measures the amount of precipitation
What is a rain gauge?
Where do most of the air masses that are warm and moist come from?
What is over the Gulf of Mexico, Atlantic, Pacfic and maritime tropical - near the equator?
Being near an ocean coast always has this type of climate
What is a wetter climate?
Determining relative wind speed by looking at isobars- lighter winds show a slow change with lines that are ________stronger winds show a rapid change when lines are ________
What is farther apart and closer together?
Warm fronts bring in the following conditions: temp, precipitation
What is warm temps and just precipitation?
Measure the wind direction
What is a weather vane?
Air masses tend to move from this direction to that direction.
What is from west to east across the U. S. ?
Define the relationship between climate and latitude
What is the higher the latitude the cooler the climate?
Describe the following characteristics of low pressure: Air temp, moving,skies,temperature, precipitation,humidity
What is warm air rising, clouds, warmer, storms, more humidity?
Storms occur at where in cold/ warm front
What is at a cold front right at the front, and at a warm front will be in ahead?
Measures the air pressure
What is a barometer?
Two things that cause global winds
What are unequal heating of the earth and the rotation of the earth?
This is part of the global wind belt that can move up and down and as it blows around the Earth can affect the temperature
What is the jet stream?
Describe the following characterisitcs of high pressure: Air temp, moving,skies,temperature, precipitation,humidity
What is cold temperatures and the air is sinking,clear skies, cooler, none, less humid?
What is an isotherm and how do you find the temperature?
What is the lines that connect the areas with the same temps. The locations between the 2 isotherms have a temp that will range between the 2 lines?
Measures wind speed
What is a anemometer?
This causes global winds to curve and why
What is the coricolus effect because of the earth's rotation?
Coastline and inland land mass have ( smaller/larger) fluctuations in temperatures
Coastlines have smaller fluctuations and inland has larger fluctuations?
