Currents...wrong data ??
-
Pls, be advised that the figures of currents in the specific location are wrong. If you interpolate the data in the area you have to reconsider that.
Best Regards.

Yes, it seems you are right. Over-interpolation is problematic.

Also ...
I observed that the problem is bigger in the equator (locations A,B,C).
Kuroshio current (east from Taiwan) seems to be OK.

Κύριε Κωνσταντίνου,
ελπίζω οι διαχειριστές να διορθώσουν αυτή την ατέλεια.
Σας εύχομαι "καλές θάλασσες"!

@nikonstantinou Hi, I checked it and these values are contained in the original data.
We use the following source: "OSCAR third degree resolution ocean surface currents".
Link: https://podaac.jpl.nasa.gov/dataset/OSCAR_L4_OC_third-deg
It is analysis which is calculated once per 5 days. The actual one is from the 17th of April.
Sea currents is not our major feature, but if you have a tip/link to better data, please share it and we will consider replacement of the data source (maybe there is available even forecast).

I think we compare apples and oranges!
Sea currents from OSCAR are calculated (mostly) from satellite real time data
while NCEP/EMC/MMAB curents are forecast products calculated from NOAA's Global Ocean Model.

The OSCAR source data is provided in a 20NM grid and typically has gaps at coastlines and in shallow bank areas. @meteo-GR, I think you are right - that the interpolation in windy.com visualization is creating artifacts that are not supported by the source data. See the comparison below:
