Living in the big bowl of atmosphere we call weather

Living in the big bowl of atmosphere we call weather
Sort of like capturing a ghost on film, there are a lot of interesting facets to weather that are difficult to grasp just staring out the window the naked eye. But put it on time lapse, and some of weather's hidden treasures can become more obvious.

Our resident time lapse weather expert, Dr. Dale Ireland, was kind enough to send in a few more of his awesome time lapse videos from the past week. Each one he sends is like a textbook that can help us visualize how weather works in a way just text on computer screen or a still photo could never do.

Today's lessons: It gets windy after a storm, and air acts a lot like water.

First of all, here is the time lapse from Saturday's rainy/sunny/windy weather. Of note to watch for here is:

* Watch the clouds continue to roll over the Olympic Mountains. It's amazing how the clouds are flowing, but yet the main cloud itself seems stationary.

* Best note: watch at the end of the lapse, the clouds speed up some. The speed of the time lapse is constant, but the clouds accelerate because the upper level winds became much faster Saturday afternoon in the wake of the trough passing the area.

And here is a time lapse from August 1st. This was pretty much a slow, sunny weather day, but of note to me is to watch the fog in the valley there on the bottom right.

The fog will slosh around as if it's water in a bucket that's being shaken. Now, if you're underneath that fog bank, you'd never know, but through the magic of time lapse, you can see just how fluid the atmosphere is.
