How Can It Be Windy At The Top Of Trees, But Not At The Bottom?

SEATTLE - Colleen wanted to know how it is sometimes, if you look at really tall trees, it'll look like it's really windy near the top, yet close to the ground, the leaves and shrubs are barely rustling?

Wind speeds tend to slow down near the ground due to interference. Buildings, trees, hills, grass, etc., all help in blocking or interfering with the flow of air. So, it will usually feel a lot less windy if you're standing at the base of the Space Needle than if you were standing on the observation deck.

On the other hand, building can sometimes funnel air between them, increasing the wind speeds. That's why it can be a lot windier while walking the streets of downtown Seattle, as opposed to flatter, residential areas.

When I saw this dramatic cloud to the north, it reminded me of smoke, rising in billows until it hits the jet stream, then it's pulled hundreds of miles east. I had to capture it quickly. Within minutes the effect had faded.

For my girlfriends birthday we had a party at her parents. We knew the nest was there but the owner hadn't seen or heard the osprey for a day or two. He asked me to fly my drone up and see if any was wrong. I flew up and found that there were two eggs inside.
