RISThe Shift of the Northern Node of the NAO and Cyclonic Rossby Wave Breaking
Publisher: American Meteorological Society
Abstract: everal studies have found an eastward shift in the northern node of the North Atlantic Oscillation (NAO) during the winters of 1978?97 compared to 1958?77. This study focuses on the connection between this shift of the ...
Tropospheric Rossby Wave Breaking and the SAM
Publisher: American Meteorological Society
Abstract: n objective analysis of tropospheric anticyclonic- and cyclonic-breaking Rossby waves is performed for the Southern Hemisphere in austral summer (December?February) of 1979?2009. The climatology of both anticyclonic and ...
Estimation of Extreme Wind Load on Structures and Claddings
Publisher: American Society of Civil Engineers
Abstract: A modified Cook-Mayne method is proposed for extreme wind load estimation. A technique that can simulate true r-order extreme values of a correlated random process is adopted in this method to estimate the annual multiorder ...
Observational Evidence of the Influence of the Qinghai-Xizang (Tibet) Plateau on the Occurrence of Heavy Rain and Severe Convective Storms in China
Publisher: American Meteorological Society
Abstract: The advance and distribution of the belts of rainfall and heavy rainfall in China are closely related to sudden seasonal changes in the general circulation over East Asia. but the latter, to a great extent, may be the ...
Observational Evidence of Frontal-Scale Atmospheric Responses to Kuroshio Extension Variability
Publisher: American Meteorological Society
Abstract: his study investigates the regional atmospheric response to the Kuroshio Extension (KE) using a combination of multiple satellite observations and reanalysis data from boreal winter over a period of at least a decade. The ...
Study on Building Digital-Twin of Face-Milled Hypoid Gear From Measured Tooth Surface Topographical Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A highly accurate digital-twin spiral bevel gear or hypoid gear is often required for dynamic analysis or stress analysis for gear transmission. However, a highly accurate digital-twin solid model is not always available ...
A Mathematical Model for Grinding a Stick Blade Profile to Cut Hypoid Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutter head with multiple stick blades is widely used in the mass production of hypoid and spiral bevel gears because they allow more blades per revolution of the head cutter. However, the stick blade geometry for a head ...
Simulation of r Highest-Order Extreme Values of Correlated Random Process
Publisher: American Society of Civil Engineers
Abstract: Several existing methods on the extreme value estimation and signal simulation are reviewed in this study with evaluation of their performances in the simulation of the
Parameter and Aerodynamic Force Identification of Single-Degree-of-Freedom System in Wind Tunnel Test
Publisher: American Society of Civil Engineers
Abstract: The extended Kalman filter with unknown inputs (EKF-UI) method has been extensively studied for application in system and input identification of multiple-degrees-of-freedom systems. The inverse problem is, however, ...
A Novel Asymmetric Face Gear Cut by Duplex Face-Milling With Multiple Auxiliary Flank Modification Motions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Face gear sets, comprising a face gear and a cylindrical pinion, are used in the crossed axes transmission with the advantages of easy assembly and a large gear ratio. Based on the geometry of a pinion tooth flank, the ...
