                         root zone spin-up time ranges from a few months to one year. The 
                         drainage layer spin-up time ranges from one to ten years. The 
                         influence of the root zone soil moisture on evapotranspiration 
                         depends on two factors: precipitation variability, which acts to 
                         weaken the influence; and soil moisture deficit, which acts to 
                         strengthen it. Therefore, in dry regions where the precipitation 
                         variability is small, evapotranspiration and root zone spin-up 
                         time are almost the same. In order to reduce the spin-up time, a 
                         new initialization is proposed. Instead of using climatological 
                         values, the equilibrium soil moisture derived from a long run of 
                         the CPTEC AGCM is used as initial condition. In general, the new 
                         initialization leads to a large reduction of the spin-up time. 
                         Therefore, for climate studies using the CPTEC AGCM, the new 
                         initialization would be recommended. However, since all the 
                         results were obtained for November and using 6-month runs, further 
                         tests are necessary.",
