Global water residence time Using data from Table 2.6 in Dingman; populate the table below and calculate the global mean residence time of water in atmospheric, terrestrial, and oceanic reservoirs. Show your calculations on engineering paper for one reservoir.
Residence time (years)
Residence time (days)
Volume (km^3)
Water in (km^3/yr)
Water out (km^3/yr)
Reservoir
Atmospheric
Terrestrial
Ocean
Describe the differences in residence time between the three reservoirs. Is one significantly longer/shorter than the others? What physical mechanisms cause the differences in residence times between the three reservoirs?
