Mountain Shadowsand Climate Graphs

Looking at how they fit into regions

Rain Shadows Remember key points Cold Clouds Can’t Contain Precipitation – they rain it

out Warm Clouds Will Wrangle their Weather – holding it in

As clouds climb up a mountain – they get COLD As clouds go down a mountain – they get WARM

Windward – wind pushes air/cloud up, Windward is WET

Leeward – mountain blocks wind, air/cloud goes down, Leeward is DRY – RAIN SHADOW

Air Cools as it rises, pushed by windWhen it gets too cold, the air squeezes out the rain on the WINDWARD side.

As air is now empty, it moves over the mountain, warming and descending.Leeward side is dry = RAINSHADOW

What is up this week Tuesday, we are going to the Museum in

Whistler We will have a chance to work through

summary notes on the regions, on Wednesday.

We will be having a short quiz on Thursday next week on the regions after the presentations.
