Abstract

We recently received a VR grant on 'Simulating green Sahara with an earth system model' . For the project we planned several equilibrium simulations with coupled EC-Earth and LPJ-GUESS model, as well as a 2000 years long transient simulation. These simulations aim to test the capability of the ESM to reproduce a greening of Sahara under certain climate conditions. If the model can reproduce this expected results, further studies will focus on understanding the reason for the abrupt change happened in the past and may happen in the near future. The mechanism involved including the vegetation-dust-climate integration. In 2018 we will start the paleo simulations for CMIP6. The new implemented component LPJ-GUESS and carbon cycle are particularly important for paleo experiments, though higher demands on computer resources will be needed. We will perform these simulations by sharing among several relevant projects such as NSC large project in Bolin Centre. Our modelling group now consists one senior scientist (myself) who is actively running the model simulations, together with two scientific programmers Qiang Li and Jenson Zhang, as well as two PhD students. We also have master students and visiting scholar analysing the model results for different projects.
