Persian Gulf rain contributions, there is still a deficit of 416 cubic kilometers per year. This difference is supplied by currents at the Strait of Hormuz. The water from the Gulf has a higher salinity, and therefore exits from the bottom of the Strait, while ocean water with less salinity flows in through the top. Another study revealed the following numbers for water exchanges for the Gulf: evaporation = -1.84m/year, precipitation = 0.08m/year, inflow from the Strait = 33.66m/year, outflow from the Strait = -32.11m/year, and the balance is 0m/year.
