Abstract. We study the rate of growth of sharp fronts in the quasi-geostrophic and
2D incompressible Euler equations. The development of sharp fronts are
due to a mechanism that piles up level sets very fast.
Under a semi-uniform collapse, we obtain a lower bound of
the minimum distance between the level sets.
