When you look at a live radar, what does it mean when there is black in the middle of all the other colors?

Answer 1

Do you mean the black circle? that would be where the radar is located, it dosent scan directly above itself so there is a blind spot there

is this what you are talking about? botton left hand corner

Answer 2

I'd have to see the image because different sites use different scales. It would also probably depend on the type of radar image you're looking it. But in general, it would probably mean "non-detection" (ND)...that, for some reason, the data isn't available for that area (computer error, radar error, etc.).

If its always showing up black regardless of time or weather, its probably some sort of geographical thing in the way (mountain, etc.) or perhaps out of the radar's range.

Answer 3

That's usually a shadow to the radar, like a mountain. The radar can't see behind the mountain, so it shows up black. If there is another radar that is on the other side of the mountain, but like in another state, then if you combine the 2 radar images, you can see on the other side of the mountain far away, but not up close.

Answer 4

I think you are talkin about where the radar is...like the other person said, it can't pick up anything right over it...therefor, there is a round blk spot there. Sometimes the radar will have incomplete data, but it will be soild blue.

I use radar software, and I can use all the radars in the United States.
