RISExperimental and Numerical Investigation of Inlet Dimple in Point and Elliptical Contact Elastohydrodynamic Lubrication Films
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The experimental observation of the inlet dimple of the elastohydrodynamic lubrication (EHL) film was carried out in point and elliptical contacts, respectively, and then, the numerical analysis under point contacts was ...
Assimilation of T-TREC-Retrieved Winds from Single-Doppler Radar with an Ensemble Kalman Filter for the Forecast of Typhoon Jangmi (2008)
Publisher: American Meteorological Society
Abstract: tropical cyclone (TC) circulation Tracking Radar Echo by Correlation technique (T-TREC) developed recently is applied to derive horizontal winds from single Doppler radar reflectivity Z data (combined with radial velocity ...
Conversion Timing of Tunnel Excavation Methods in Upper-Soft and Lower-Hard Stratum Based on Displacement Direction Angle Theory: Case Study
Publisher: American Society of Civil Engineers
Abstract: Zi-Zhi Tunnel is a shallow-buried tunnel, and its geological conditions are generally upper soft and lower hard. Therefore, the designed excavation methods are the center diaphragm method and the bench method. For the ...
The Gradient Velocity Track Display (GrVTD) Technique for Retrieving Tropical Cyclone Primary Circulation from Aliased Velocities Measured by Single-Doppler Radar
Publisher: American Meteorological Society
Abstract: he ground-based velocity track display (GBVTD) technique was developed to estimate the primary circulations of landfalling tropical cyclones (TCs) from single-Doppler radar data. However, GBVTD cannot process aliased Doppler ...
Kinematics and Microphysics of Convection in the Outer Rainband of Typhoon Nida (2016) Revealed by Polarimetric Radar
Publisher: American Meteorological Society
Abstract: AbstractThis study analyzes the microphysics of convective cells in an outer rainband of Typhoon Nida (2016) using data collected by a newly upgraded operational polarimetric radar in China. The life cycle of these convective ...
Quantitative Precipitation Estimation with Operational Polarimetric Radar Measurements in Southern China: A Differential Phase–Based Variational Approach
Publisher: American Meteorological Society
Abstract: AbstractQuantitative precipitation estimation (QPE) with polarimetric radar measurements suffers from different sources of uncertainty. The variational approach appears to be a promising way to optimize the radar QPE ...
Doppler radar analysis of a tornadic miniature supercell during the Landfall of Typhoon Mujigae (2015) in South China
Publisher: American Meteorological Society
Abstract: n 4 October 2015, a miniature supercell embedded in an outer rainband of Typhoon Mujigae produced a major tornado in Guangdong Province of China, leading to 4 deaths and up to 80 injuries. This study documents the structure ...
