Cartoon
of nonlocal interaction
¥Eddy
scale L
decreases via shearing by ZF
¥Potential
enstrophy Z
is conserved.
¥=>
Eddy energy E =Z L2 is
decreasing
¥Total
E is conserved, => E is transferred from the eddy to ZF
¥Wrong! Both smaller and
larger LÕs
are produced. The energy of the eddy is unchanged. (Kraichnan 1976).
