Hi I'm studying about vortex in cell method

While I'm studying, I have a question about enstrophy.

I just know that enstrophy is volume integral of

vorticity's square value.

But what does enstrophy means?

what kind of relation does enstrophy has with flow?

when enstrophy is high, Are flow unstable? Is this right?

Thank you for reading this article.
