*Jet Stream

*Jet Stream
*Forms high in the upper Troposphere between two air masses of different temperatures
*Higher temperature difference = faster speed
*Due to the Coriolis Effect, it flows around air masses.
*Polar Jet:
*It dips southward when frigid polar air masses move south.
*It tends to stay north in the summer months

Abnormally high surface ocean temperatures off the coast of South America
Causes unusual weather patterns across the globe
*El Nino

*A strong surface current
*Begins at the tip of Florida
*Flows up the eastern coastline of the
U.S.
*Crosses the Atlantic Ocean
*Causes warmer climate in NW Europe
*Gulf Stream

*Reflection Question
*Why does the Earth have wind and ocean currents?

*Variables Affecting Local Weather
![Page 17: 0 o Equator 30 o S 60 o S 90 o S 30 o N 60 o N90 o N More Direct Sun Hot.](https://reader035.fdocuments.in/reader035/viewer/2022070401/56649f1f5503460f94c36adc/html5/thumbnails/17.jpg)
*Fronts
*When convection and winds cause air masses to move, they bump into one another.
*The area where two air masses meet is called a front.
*Most severe weather occurs near frontal boundaries.

*Cold Front- Cold air meets warm air- Fast moving and stormy, severe weather is likely
![Page 20: 0 o Equator 30 o S 60 o S 90 o S 30 o N 60 o N90 o N More Direct Sun Hot.](https://reader035.fdocuments.in/reader035/viewer/2022070401/56649f1f5503460f94c36adc/html5/thumbnails/20.jpg)
*Warm Front- Warm air meets cold air- Slow moving with less severe weather
![Page 22: 0 o Equator 30 o S 60 o S 90 o S 30 o N 60 o N90 o N More Direct Sun Hot.](https://reader035.fdocuments.in/reader035/viewer/2022070401/56649f1f5503460f94c36adc/html5/thumbnails/22.jpg)
*Stationary Front
*Warm and cool air masses that are not strong enough to move one another
*Sits still for a long period of time

*High and Low Pressure Circulation
![Page 27: 0 o Equator 30 o S 60 o S 90 o S 30 o N 60 o N90 o N More Direct Sun Hot.](https://reader035.fdocuments.in/reader035/viewer/2022070401/56649f1f5503460f94c36adc/html5/thumbnails/27.jpg)
*Air Pressure and Wind
*Air pressure is measured with a barometer in millibars.
*Millibars are represented by connected lines of equal pressure. This is a lot like the topographic map lines.
*The closer together the lines are, the faster the wind speed.
*The farther apart the lines are, the slower the wind speed.

*The Earth’s Insulator
*The Sun heats the water and land every day.
*Land heats up rapidly, but cools off rapidly.
*Desert
*Water heats up slowly, but cools off slowly.
*Swimming at night
*The heat retained by the oceans is what keeps our planet insulated.

*Land and Sea Breezes
*The heating and cooling of water and land produces land breezes and sea breezes.
*High pressure moves toward low pressure, pushing the warm air upward.
*As warm air rises, cooler air moves in and replaces it.

*Reflection Question
*How do global patterns of atmospheric movement affect local weather?
