This map shows the normal path of the subtropical jet stream over North America. Scientists have observed that the subtropical jet stream is moving farther north. How could this movement affect climatic conditions in North America?

• Rainfall in the southern states could decrease.

• Air pressure over North America could increase.

• The number of hurricanes in the Atlantic Ocean could decrease.

• Warm, tropical conditions in the southern states could increase.

What is a cold front?

• front when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow)

• The temperature at which condensation begins

• very cold, very dry stable air mass

• A boundary between air masses that don't move possibly causing rain for several days

What is a stationary Front?

• unstable cold, moist air mass that forms over cold oceans--

  Winter and Summer- cold and humid

• very cold, very dry stable air mass

• unstable, warm, dry air mass that forms over land

  Winter - warm and dry

  Summer - Hot and dry

• A boundary between air masses that don't move possibly causing rain for several days
