Wave-mean decomposition of scale-dependent kinetic energy from surface drifters
Han Wang, Dhruv Balwada, Jin-Han Xie
Separating waves and mean flows is a fundamental challenge in ocean dynamics. Lagrangian filtering of passive-tracer time series into high-frequency wave and low-frequency mean-flo…
Area rule of velocity circulation in two-dimensional instability-driven turbulence beyond the inertial range
Bo-Jie Xie, Tian-Shu Zhou, Jin-Han Xie
The velocity statistics reveal non-universality in both three-dimensional (3-D) and two-dimensional (2-D) turbulence, despite both prototype systems containing an energy inertial r…
Multi-range fractional model for convective atmospheric surface-layer turbulence
Fei-Chi Zhang, Jin-Han Xie, Xiaojing Zheng
We develop a multi-range fractional (MRF) model to capture the turbulent spectrum consisting of multiple self-similar ranges impacted by multiple effects. The MRF model is validate…
Energy spectrum of two-dimensional isotropic rapidly rotating turbulence
Peiyang Li, Jin-Han Xie
We study a two-dimensional isotropic rotating system and obtain both theoretically and numerically a energy spectrum under the rapidly rotating condition (), whic…
