Outline of Final Research Achievements |
This study investigates the influences of land cover change on the amount of precipitation over land in the Borneo Island, using numerical simulations with the Weather Research and Forecasting model. The simulation of forest degradation, in which stomatal conductance was reduced, resulted in increase in monthly accumulated precipitation (Pac) over land, even though monthly accumulated evapotranspiration (Eac) decreased. This was likely attributed to enhanced convergence of water vapor flux (Qf) in the inland area in nighttime. By contrast, two cases of the simulations of deforestation resulted in decrease in Pac over land. The amplitude of decrease in Pac was nearly proportional to the deforested area. This was likely attributed to weakened convergence of Qf in the coastal land area in late afternoon and in the inland area in nighttime. Drying of the atmosphere caused by the weakened convergence of Qf induced lifting of condensation level and weakened the atmospheric instability.
