RISCase Study of Potential Vorticity Tower in Three Explosive Cyclones over Eastern Asia
Publisher: American Meteorological Society
Abstract: hree cases of explosively developing extratropical cyclones over eastern Asia are analyzed using ERA-Interim data. The morphological characteristics of the upper-tropospheric potential vorticity (PV) were examined. The ...
Determining the Extratropical Transition Onset and Completion Times of Typhoons Mindulle (2004) and Yagi (2006) Using Four Methods
Publisher: American Meteorological Society
Abstract: our methods for determining the extratropical transition (ET) onset and completion times of Typhoons Mindulle (2004) and Yagi (2006) were compared using four numerically analyzed datasets. The open-wave and scalar frontogenesis ...
Characteristics of Explosive Cyclones over the Northern Pacific
Publisher: American Meteorological Society
Abstract: AbstractExplosive cyclones (ECs) over the northern Pacific Ocean during the cold season (October?April) over a 15-yr (2000?15) period are analyzed by using the Final (FNL) Analysis data provided by the National Centers for ...
A Polar Low over the Japan Sea on 21 January 1997. Part II: A Numerical Study
Publisher: American Meteorological Society
Abstract: A remarkable isolated polar low observed over the Japan Sea on 21 January 1997 is studied by numerical simulations using a 20-km-mesh regional primitive equation model [Regional Spectral Model (RSM) of the Japan Meteorological ...
A Polar Low over the Japan Sea on 21 January 1997. Part I: Observational Analysis
Publisher: American Meteorological Society
Abstract: A polar low was observed over the Japan Sea on 21 January 1997. Part I of this paper focuses on the observational analyses by using all available observational data from surface meteorological stations, Geostationary ...
A High-Resolution Simulation of Typhoon Rananim (2004) with MM5. Part I: Model Verification, Inner-Core Shear, and Asymmetric Convection
Publisher: American Meteorological Society
Abstract: In this study, the fifth-generation Pennsylvania State University?National Center for Atmospheric Research (PSU?NCAR) Mesoscale Model (MM5) is used to simulate Typhoon Rananim (2004) at high resolution (2-km grid size). ...
Multiple Polar Mesocyclones over the Japan Sea on 11 February 1997
Publisher: American Meteorological Society
Abstract: The characteristics and development mechanism of four meso-?-scale polar mesocyclones (M?PCs), which appeared as a vortex train over the Japan Sea from 0000 to 1700 UTC on 11 February 1997, are studied by means of observational ...
Assimilating MTSAT-Derived Humidity in Nowcasting Sea Fog over the Yellow Sea
Publisher: American Meteorological Society
Abstract: n extended three-dimensional variational data assimilation (3DVAR) method based on the Weather Research and Forecasting Model (WRF) is developed to assimilate satellite-derived humidity from sea fog at its initial stage ...
The Formation Mechanism of a Spring Sea Fog Event over the Yellow Sea Associated with a Low-Level Jet
Publisher: American Meteorological Society
Abstract: n this paper, a dense sea fog event that occurred over the Yellow Sea (YS) on 9 March 2005 is investigated using the Weather Research and Forecasting Model version 3.1.1 (WRF v3.1.1). It is shown that the WRF can reasonably ...
Real-Time Precision Tracking System in Periprosthetic Acetabular Osteotomy With Osteotome Chisel Elastic Deformation Consideration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The periprosthetic acetabular osteotomy (PAO) is a commonly used technique in orthopedics for treating developmental hip dysplasia and hip dislocation, as the most effective treatment for developmental dysplasia of the hip ...
