| Abstract | The soil moisture spin-up time of the CPTEC AGCM is evaluated. The 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. |
