ABSTRACT
USlng a three dimensional model similar to that used
by Dzukov ,the vertical components of the current velocities
in the western part of the Mediterranean Sea were calcu1ftted
for the summer season,assuming stationary conditions.
Starting with the wind speed and direction with a free
sea surface,the velocity field was calculated for the surface
(O-lOm.) layer and at other depthes .The values of the
vertical velocities with depth were of order of 10- 4
cm/sec.arid the maximum was generally at depth of 100 m. The
distribution of the vertical velocities varies only in
deta iI .
Area of upwell ing and sinking came out,sinking appearing
in ceteral part of the region, while upwell ing appeared
at the borders, obviously the north wester part of the
region .Veloc.ities in the upwelling region reached about
8-4 cm/s.The general cydanic motion in the basin maintans
the calculated upwelling:The area of sinking agree well
with th; observed area of sinki’ng of maximum salinity water
as observed by Wust.
