Newly discovered source of turbulence and heating in the solar chromosphere
Above the Sun's luminous photosphere lies the solar chromosphere, where the temperature increases from below 4000 K to over 1 million K. Though physicists do not understand the...- publication PDF

On the role of sea-state in bubble-mediated air-sea gas flux during a winter storm
Oceanic bubbles play an important role in the air-sea exchange of weakly soluble gases at moderate to high wind speeds. A Lagrangian bubble model embedded in a large eddy...- publication PDF

An air stagnation index to qualify extreme haze events in northern China
Stagnation weather affects atmospheric diffusion ability, and hence causes the occurrence of haze events, which have been happening frequently in northern China (NC). This work...- publication PDF
