Climate and Weather. Climate Average condition of the atmosphere over along period of time Includes temperature, precipitation and change from one season.
 Weather depends on what type of air mass is over an area and whether or not the spot is under a front.  The air masses and how they interact will determine.

Global Climate Change and the Jetstream 1/7/14

Do Now: Post Activity Discussion 1.What is the Jetstream and what does it separate? It is a fast moving, upper-level wind (in the Stratosphere) It separates cold air from the north and warm air from the south 2.Why is the Jetstream important? It is the most important factor for our daily weather It carries and mixes our air masses creating the weather and severe weather 3.How has the Jetstream changed? Loss of Arctic ice and a warmer Arctic have slowed (it can stop over regions) and weakened (can be pushed out of the way by stronger air masses such as an Arctic air mass) 4.What is causing the Jetstream to change? Global Warming/Global Climate Change 5.What will be future impact of these changes? More extreme weather for longer periods of time, more severe storms, droughts and floods
