What is a jet stream?

• Fast moving air traveling behind a jet airplane

• Large circle like patterns of air and water in the Pacific Ocean

• A fast moving air current moving from west to east around Planet Earth

Where do jet streams form?

• Where cold air from the poles meets warm air from the equator

• Where upwelling in the ocean meet warm water surface water

• Where air planes flight patterns cross

Less dense, warm air move away from the equator and towards the poles. When it cools down in the poles it becomes more dense sinks.

How are the convection currents in the student’s model different from the convection currents in Earth’s atmosphere and oceans?

• The warm air in Earth’s atmosphere and the warm water in Earth’s oceans sink instead of rise.

• The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below.

• Convection cells in Earth’s atmosphere and oceans flow in the same direction instead of opposite directions.

• Cold air in Earth’s atmosphere and cold water in Earth’s oceans are less dense than warm air and warm water instead of being more dense.

Air moving away from the the equator towards the poles moves in a circular motion because Earth spins.

Why is the North Atlantic Jet Stream important for our climate in the Pacific Northwest?

• It brings air from over the ocean to our shores helping to keep our winters more mild

• In the summer months it help create our Northerly winds which cause ocean upwelling

• It helps to move weather systems like rain across our region

• It's position affects can affects the amount of snow we receive in the winter
