| Zusammenfassung |
| The natural evaporation in the Dead-Sea is a very important meteorological parameter to the
local industries at Sdom. It was found that the pan evaporation in Sdom has recently
increased by 20-25%. We explore the reasons for this increase. It is found that both
large-scale and local climatic changes have contributed to the evaporation increase in the
Dead Sea, Sdom. The large-scale (global) change, potentially associated with the global
warming, increases the frequency of the hot synoptic systems in the region. The local change
is a result of the recent Dead-Sea drying, which reduced the local Dead-Sea breeze while
intensifying the Mediterranean-Sea breeze penetrating the Dead Sea Valley. It is
suggested that while the local effect was the dominant climatic change factor in the
Dead-Sea Valley in the 1970-1990, the global effect becomes the dominant one
in the more recent evaporation increase in the Dead-Sea. In general, the method
presented here is a novel approach for the separation of a local contribution from
the large-scale or global effect, exemplified here by the Dead-Sea evaporation. |
