Influences of Cities and Lakes on a Shear Line Rainstorm Process in East China

Gaoyuan qixiang, 2022
Cities and lakes have obvious influences on regional precipitation， but their single or interaction effects on reginal heavy rain process remain to be quantified.To reveal the effects of interactions between cities and lakes on the process of heavy rain，

Dynamical age of solar wind turbulence in the outer heliosphere [PDF]

, 1998
In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity.

Impact of Lidar Data Assimilation on Low-Level Wind Shear Simulation at Lanzhou Zhongchuan International Airport, China: A Case Study

Atmosphere, 2020
Doppler wind lidar has played an important role in alerting low-level wind shear (LLW). However, these high-resolution observations are underused in the model-based analysis and forecasting of LLW.

Airport low-level wind shear lidar observation at Beijing Capital International Airport [PDF]

Infrared Physics & Technology, 2019
Abstract The low-level wind shear is defined as a sharply change of the wind speed or wind direction within 600 m above the ground level. Due to affecting the airspeed of aircraft during take-off and landing phases, the wind shear can result in the disastrous aircraft accidents.

Assessing wind profile effects on the global atmospheric torque [PDF]

, 2009
The impact of a new approach to the evaluation of surface gravity wave drag (GWD) is assessed. This approach uses linear theory, but incorporates the effects of wind profile shear and curvature, by means of a second-order WKB approximation.

Impact of non-hydrostatic effects and trapped lee waves on mountain wave drag in directionally sheared flow [PDF]

, 2015
The orographic gravity wave drag produced in flow over an axisymmetric mountain when both vertical wind shear and non-hydrostatic effects are important was calculated using a semi-analytical two-layer linear model, including unidirectional or directional

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...
