The least you could do is provide some sort of executive summary.

You can tell when it's spring on account of all the polka dots.

I'm admitting it, youtube posts don't come with executive summaries.

What is up with the polka dot pattern? Is that an artifact of radar placement, or do rainstorms really form in patterns like that?

I suspect the polka dot pattern is just "ground clutter" around the radar sites.

And form the same polka dot pattern three times over three days. Weird.

Is this another thing I'd need to live in the US to understand?

Only if the US is the only country with people who think weather patterns are interesting.

In a word: Obama.

The pulsing is "clear air mode." During clear weather, the radar is turned to extremely high sensitivity. It picks up more ground clutter, hell, it can pick up flocks of insects. Clear air mode is often used at night and is turned back to regular mode during the day. Thus the pulsing effect.

It seems like every US weather map I see has these "radar-borders", so that we never see the weather in Mexico or Canada. Why is that? Are there regulations on what we can see on a weather map? I know that this video, and lots of other displays, maps, whatevers, are "US" weather maps, but not seeing systems until they appear at our borders has always seemed odd to me. Regulations? Processing cost? What?

The data in the video comes from WSI (The Weather Channel) and Nexrad. American radar on American soil.
