Because pressure toward downward direction is positive and toward upward direction is negative.

Sometimes a weir is not fully ventilated, but is partially ventilated as shown in fig-2 (b). If the pressure below the nappe is negative, it is called a depressed nappe. The discharge of the nappe, in this case, depends upon the amount of ventilation and the negative pressure.
Generally, the discharge of a depressed nappe is 6% to 7% more than that of a free nappe. I hope it'll help you.
