My personal research interests cover a wide range of topics under the BIG envelope of climate change and Earth system sciences, and their consequences towards human society.

I have been involved in the modelling development (land surface and vegetation, including terrestrial carbon cycle dynamics) of an Earth system model of intermediate complexity------the "Green" McGill Paleoclimate Model (MPM), which has been used to help understand climate changes from last glacial inception to Holocene (see Wang et al., Climate of the Past, 2009).

I have been involved in the first long-term (6500-year) fully coupled climate model (FOAM) study for the Holocene (aimed to understand ABRUPT CLIMATE CHANGES), which has been highlighted by top-ranking journals, such as NATURE, SCIENCE, NATURE GEOSCIENCES, and PNAS. The successful modelling of abrupt ecosystem collapses in mid-Holocene North Africa is encouraging a further study of the mechanisms of these abrupt changes in the past and mostly likely in the future (see Wang et al., Climate of the Past, 2008).

I have been analysing the decadal surface radioation measurement and retrievals from the USA Department of Energy Atmospheric Radiaiton Measurement (ARM) program over Manus Island (Papua New Guinea). I used a wide-range statistical tools to extract the well-known Madden-Julian Oscillation (MJO) from ARM observations ( see Wang et al., Climate Dynamics, 2011).

I have initiated an integrated systematic evaluation of cloud microphysics schemes in one of the most advanced regional climate model (WRF) (see Wang et al., JGR, 2009). Future generations of global climate models will most likely be run at very high-resolution (a few kilometres) so that the convective parameterization will not be crucial. Under such "cloud-permitting" scales, different cloud microphysics will play significant roles to guide the performance of the next generation of global climate models. This cutting-edge research was highlighted at PNNL Inside News (Dec. 21, 2009), Division of Atmospheric Sciences and Global Changes Research Highlights, and was listed among FOUR most significant research achievements in 2009 USA DOE ARM Annual report. Further researches have been carried out with foci on cloud aerosol interactions and ice cloud microphysics in the tropics.

I have strongly involved in understanding the Madden-Julian Oscillation (MJO) through my co-investigation in USA Department of Energy funded field campaigns, namely, ARM MJO Investigation Experiments, which are parts of international ongoing efforts called CINDY2011 and DYNAMO.
