[ferret_users] Sverdrup Streamfunction - indefinite integral with irregular boarders
I am trying to calculate and plot with FERRET the Sverdrup
Streamfunction from the wind stress curl curl_tau
acording to the formel:
Psi = 1/beta Int_xlim(y) ^x curl(tau)dx, xlim (y) is the longitude
of the boundary at each latitude.
I use the following definition (for the pacific ocean):
LET PSI = IF curl_tau[x=160E:0@iin] THEN (1/(beta*rho_ocean))*(
(-1)*curl_tau[x=160E:0@iin] + curl_tau[x=160E:0@din] )/1E06 ELSE 0
fill PSI ; go land
the result is as in the attached GIF-image, but it is not sutisfing. I
have the following problem:
- the islands(Hawaii, New Zeland, ...) and the Continent (Australia)
disdurb the calculation (no streamfunction behind the land-boarders).
The problem is computing an indefinite integral in an area with
irregular boundaries.
How can I solve this? Can someone help?
best regards
Theodor
