Effects of Regional Transport on Haze in the North China Plain: Transport of Precursors or Secondary Inorganic Aerosols

open access: yesGeophysical Research Letters, 2020
Most previous studies treat regional transport of aerosols as a whole, without distinguishing the transport of secondary aerosols and that of their precursors.

Haze pollution under a high atmospheric oxidization capacity in summer in Beijing: insights into formation mechanism of atmospheric physicochemical processes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Under a high atmospheric oxidization capacity, the synergistic effect of the physicochemical processes in the atmospheric boundary layer (ABL) caused summer haze pollution in Beijing.

Grain Boundary Driven Plateau-Rayleigh Instability in Multilayer Nanocrystalline Thin Film: A Phase-field Study

open access: yes, 2016
Thermal stability of nanocrystalline multilayer thin film is of paramount importance as the applications often involve high temperature. Here we report on the layer instability phenomenon in binary polycrystalline thin film initiating from the grain ...

Boundary and interior layers [PDF]

open access: yesPhysics Bulletin, 1982
The second international conference on boundary and interior layers – computational and asymptotic methods, BAIL II – was held at Trinity College, Dublin, Ireland, on 16–18 June 1982, under the auspices of the College's Numerical Analysis Group. It was cosponsored by the American Institute of Aeronautics and Astronautics, the American Meteorological ...

Edge states in a boundary layer [PDF]

open access: yesPhysics of Fluids, 2011
The understanding of laminar-turbulent transition in shear flows has recently progressed along new paradigms based on the central role of nonlinear exact coherent states. We follow such paradigms to identify, for the first time in a spatially developing flow, localized flow structures living on the edge of chaos, which are the precursors of turbulence.

Quantitative study on the water vapor transport characteristics of an extreme precipitation event in North China

open access: yesAtmospheric Science Letters
North China experienced an extreme precipitation event from July 29 to August 1, 2023 (i.e., the “23.7” event) causing severe floods, significant infrastructure damage and multiple fatalities.

Homogenization and boundary layers [PDF]

open access: yesActa Mathematica, 2012
This paper deals with the homogenization of elliptic systems with Dirichlet boundary condition, when the coefficients of both the system and the boundary data are e-periodic. We show that, as e → 0, the solutions converge in L2 with a power rate in e, and identify the homogenized limit system. Due to a boundary layer phenomenon, this homogenized system

The monsoon effect on energy and carbon exchange processes over a highland lake in the southwest of China [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Erhai Lake is a subtropical highland shallow lake on the southeast margin of the Tibetan Plateau, which is influenced by both South Asian and East Asian summer monsoons.

Influence of higher order effects on the vortex instability of thermal boundary layer flow in a wedge shaped domain [PDF]

open access: yes, 2005
We reconsider the onset of streamwise vortices in the thermal boundary layer flow induced by an inclined upward-facing heated semi-infinite surface placed within a Newtonian fluid.

Vertically resolved characteristics of air pollution during two severe winter haze episodes in urban Beijing, China [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
We conducted the first real-time continuous vertical measurements of particle extinction (bext), gaseous NO2, and black carbon (BC) from ground level to 260 m during two severe winter haze episodes at an urban site in Beijing, China.
