Abstract

In this study the extreme precipitation under different CCSM3 GCM GHG emissions scenarios is investigated between historical period (wy1901 - wy1999) and projection period (wy2001 - wy2099) for the watersheds in northern California. For this, a regional climate model (MM5) was set up over northern California and then the precipitation was dynamically downscaled from CCSM3 GCM GHG emissions scenario outputs to a regional scale (9-km grid resolution) with 1-hour time increments for both the historical period (1900 - 2000) and the projection period (2000 - 2100). From this study, it is found that the projected annual 72-hour maximum precipitation values based on CCSM3 A1B, A2, B1, and A1FI have heavier tails than the historical annual 72-hour maximum precipitation values. Furthermore, the CCSM3 A1FI scenario-based annual 72-hour maximum precipitation values are also higher than the historical annual 72-hour maximum precipitation values. In other words, A1FI scenario is one of the worst GHG emissions scenarios, but this scenario is also very important for future climate change assessment.
