2) Under what aridity indexes do the open and closed water budgets have the largest differences? What are the long-term average ET/P in the open and closed water budgets? Why do the open and closed have similar long-term average evaporative index despite differences I'm year to year ET/P (hint check the long-term water budgets of both)?.
