Re: trace the float trajectory back
The method suggested by Rodrigo certainly works. Some remarks concerning partial differential equations and reverse time. It's true that with ordinary differential equations, it suffices to set y=-t to examine reverse times. Unfortunately, partial differential equations are a little bit more complex...

Re: trace the float trajectory back
Dear Zhaoqian, Mathematically, ROMS is based upon partial differential equations. Generally, theorems ensure existence and uniqueness of the solutions only for positive times t: it means that this kind of results doesn't work for reverse (negative) times. Nevertheless, you can intuitively try to gue...
