RISImpact of El Niño/La Niña on the Seasonality of Oceanic Water Vapor: A Proposed Scheme for Determining the ITCZ
Publisher: American Meteorological Society
Abstract: Previous research has shown that oceanic water vapor (OWV) is a useful quantity for studying the low-frequency variability of the atmosphere?ocean system. In this work, 10 years (1993?2002) of high-quality OWV data derived ...
Research on Pre-Reinforced Regions and Strength Parameters of Shallow Tunnels in Weak Strata
Publisher: American Society of Civil Engineers
Abstract: Safety coefficient and surface settlement were chosen as evaluation indictors for non-self-stabilizing weak strata and basic self-stabilizing weak strata. Fluid mechanical interaction is used to analyze the pre-reinforcement ...
Dynamic Wrinkling Instability of Elastic Films on Viscoelastic Substrates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic instability of stiff films on compliant substrates has received sustained attention due to the potential applications in flexible functional devices. Film/substrate system-based devices are increasingly utilized ...
Dynamic Behaviors of Delaminated Nanofilms Partly Bonded on Substrates With Sub-Nanoscale van der Waals Dynamic Boundaries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic behaviors of delaminated nanofilms on substrates are universal and essential phenomena in nanoelectromechanical systems (NEMS). Van der Waals (vdWs) interactions play an important role in the dynamic behaviors of ...
The Weather Research and Forecasting Model's Community Variational/Ensemble Data Assimilation System: WRFDA
Publisher: American Meteorological Society
Abstract: milation is the process by which observations are combined with short-range NWP model output to produce an analysis of the state of the atmosphere at a specified time. Since its inception in the late 1990s, the multiagency ...
Four-Dimensional Variational Data Assimilation for WRF: Formulation and Preliminary Results
Publisher: American Meteorological Society
Abstract: The Weather Research and Forecasting (WRF) model?based variational data assimilation system (WRF-Var) has been extended from three- to four-dimensional variational data assimilation (WRF 4D-Var) to meet the increasing ...
