The Med is relatively chemically inactive--not enough nutrients for
sea plant life, and there is a small food chain. Further, once fresh
water sources are depleted, without fresh water capping, there is
essentially salt water sinking and the causes the deep curent to move
out the the Straights of Gilbralter--from east to west, creating on
the surface a current from west to east--that inducts AGAINST cirrus.
Watch what happens in the next few weeks in the Med -- see if we have
a big storm as a result. Normally, they get weather, if any, there in
the E. Med during the winter. Algiars was November last year--the
storm that killed 400. Eqypt had a killing squall as well the first
few days of December with a good flaring event. It may be that it is
too off season for this Syrian dam break to change much climate, but
it will be interesting to monitor.
