doubt: convergence of ocean currents

[divyadavidt]

hi everyone....
I want to know how to calculate the convergence of ocean currents mathematically.....
Thanks in advance

Dear divyadavidt

For gridded data you can use finite differences schemes. See page 16 from Piolle & Bentamy (2002). They computed wind divergence but it's the same. Positive (divergence), negative (convergence)
