Series A METEOROLOGICAL NOTES No.16 TENTATIVE ENERGY AND WATER BALANCES FOR THE DEAD SEA

摘要

The average annual rates of evaporation from the northern and southern basins of the Dead Sea are calculated from the energy balance of the sea. The resulting evaporation rates are as follows:Northern basin—150 cm yr-1 (nominally, 147 cm yr-1), southern basin — 180 cm yr-1. For the Dead Sea as a whole, the rate works out as 155 cm yr-1. Next, from a combination of the energy balance and water balance approaches, average monthly evaporation rates are derived. These figures and figures for monthly lake level change lead to estimates of monthly inflow of water into the lake. Finally, the figures for monthly inflow are partitioned into component terms in a tentative manner. One of the conclusions of the analysis is that the underground inflow of water to the Dead Sea is at most of the order of 107 m3 yr-1.
