RISHistoric Building Stones and Flooding: Changes of Physical Properties due to Water Saturation
Publisher: American Society of Civil Engineers
Abstract: Natural stone is a common material in historic constructions. Flood events may directly affect surfaces of historic stone buildings. Since ashlars and stone sculptures often carry valuable cultural information, a more ...
Applicability of Axisymmetric Analysis in Predicting Supersonic Flow Through Annular Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solutions of the differential equations of the axisymmetric model and circumferentially averaged solutions of the differential equations of the three-dimensional model are compared quantitatively ...
Northern Hemisphere Stationary Waves in Future Climate Projections
Publisher: American Meteorological Society
Abstract: The response of the atmospheric large-scale circulation to an enhanced greenhouse gas (GHG) forcing varies among coupled global climate model (CGCM) simulations. In this study, 16 CGCM simulations of the response of the ...
A Conceptual Model of the Surface Salinity Distribution in the Oceanic Hadley Cell
Publisher: American Meteorological Society
Abstract: A conceptual model of the salinity distribution in the oceanic Hadley cell is presented. The model pertains to the region of tropical easterly surface winds, where the surface salinity increases poleward from a local ...
Deformation Detection in the GPS Real-Time Series by the Multiple Kalman Filters Model
Publisher: American Society of Civil Engineers
Abstract: Global Positioning System (GPS) is widely used for monitoring some natural phenomena and man-made structures. The detection of the deformation epoch in real time is of great importance in these applications. This study is ...
A Single-Column Method to Identify Sea and Land Breezes in Mesoscale-Resolving NWP Models
Publisher: American Meteorological Society
Parshall Flume Discharge Corrections: Wall Staff Gauge and Centerline Measurements
Publisher: American Society of Civil Engineers
Abstract: Parshall flumes were developed in the early 1900s as a simple and inexpensive way to provide accurate flow measurement in open channels. Unfortunately, many Parshall flumes in use today do not follow essential design ...
The Impact of Data Assimilation Length Scales on Analysis and Prediction of Convective Storms
Publisher: American Meteorological Society
Abstract: n idealized convective test bed for the local ensemble transform Kalman filter (LETKF) is set up to perform storm-scale data assimilation of simulated Doppler radar observations. Convective systems with lifetimes exceeding ...
The Role of Stationary Waves in the Maintenance of the Northern Annular Mode as Deduced from Model Experiments
Publisher: American Meteorological Society
Abstract: The influence of stationary waves on the maintenance of the tropospheric annular mode (AM) is examined in a simple global circulation model with perpetual January conditions. The presented model experiments vary in the ...
Height Correction of Atmospheric Motion Vectors Using Airborne Lidar Observations
Publisher: American Meteorological Society
Abstract: ncertainties in the height assignment of atmospheric motion vectors (AMVs) are the main contributor to the total AMV wind error, and these uncertainties introduce errors that can be horizontally correlated over several ...
