good question.. weather radar tracks water.. imagine that.. stronger returns
means more water means a bigger storm

we used to track migrating birds with ATC primary "skin paint".. especially
in flocks.. like the "Flying V" duck formations..

the radar was reflecting off the water in the ducks bellies.., this was
confirmed when "multiple traffic" was called to an aircraft.. "type and
altitude unknown", and the response from the pilot was... "nothing over
there but a flock of ducks heading south along the river"

The only thing that reflects radar is metal or things (like paint)
that have metal in them.


Then how does weather radar work?
