Fog Explaination

Here is my idea of why the fog in Vancouver won't go away.. study the following diagram carefully..


Diagram 1.a

Just in case you can't read the labels. They say, Wind, Fog and Rockies. It's not rocket science.

Notice how the wind is blowing in a Westerly direction? This wind is blowing the fog into the Rocky mountains.
Again notice how much bigger the rocky mountains are than Vancouver? (not to mention more colourful) The fog just has nowhere to go. It is stuck on Vancouver. For ever.
