Latest Research Results


Anthropogenic aerosol emissions decreased over North America and Europe but increased over Asia since the 1970s. Our recent paper [Wang et al., 2020, Nat Climate Change] revealed that this aerosol forcing caused jet stream winds to shift poleward over the Atlantic, decreasing planetary wave activity and partially inhibiting extreme winter weather over northern Eurasia.


We use the multiple climate and satellite data to assess the causes and impacts of recent wildfires in California [Li et al., 2019, ESS]. The identified elevated greenhouse gas concentrations from the wildfires in this study call on more attention on wildfire for future climate research and policy making.

Sea Ice

[Wang et al. 2018, J. Clim.] employs a fully coupled climate model to explore effects of man-made aerosols on historical and future variations of the Arctic sea ice in comparison with the GHG forcing. Aerosol-induced cloud forcing and subsequent feedback processes are found critical.


We show significant impacts of Saharan dust on the radiative budget, hydrological cycle, and large-scale environments relevant to tropical cyclone activity over the Atlantic, by imposing temperature inversion, reducing surface solar radiation, and suppressing hurricane [Pan et al., 2018, J. Clim.].
