DOI: 10.1002/qj.3939
Abstract: Oscillations in wind speed and temperature are commonly observed in the atmospheric surface layer due to the ubiquitous presence of submeso‐scale motions (SSMs). These motions are of particular importance during stable and low‐wind conditions as… read more here.

DOI: 10.1017/jfm.2018.131
Abstract: We study the large-scale motions in turbulent plane Couette flows at moderate friction Reynolds number up to $Re_{\unicode[STIX]{x1D70F}}=500$ . Direct numerical simulation (DNS) domains were as large as $100\unicode[STIX]{x03C0}\unicode[STIX]{x1D6FF}\times 2\unicode[STIX]{x1D6FF}\times 5\unicode[STIX]{x03C0}\unicode[STIX]{x1D6FF}$ , where $\unicode[STIX]{x1D6FF}$ is… read more here.

DOI: 10.1017/jfm.2019.210
Abstract: Very-large-scale motions (VLSMs) and large-scale motions (LSMs) coexist at moderate Reynolds numbers in a very long open channel flow. Direct numerical simulations two-way coupled with inertial particles are analysed using spectral information to investigate the… read more here.
