Meridional Flow Field of Axisymmetric Flows in a Rotating Annulus
Publisher: American Meteorological Society
Abstract: Measurements of the flow field were made of the axisymmetric flow in a differentially heated rotating fluid annulus by using a long-term tracking of a tracer particle. Its meridional flow profile is composed of a flow ...
Experimental Observations of Internal Vortex Structures in Steady Baroclinic Waves
Publisher: American Meteorological Society
Abstract: The basic structures of steady baroclinic waves observed in a differentially heated rotating-fluid annulus are well known to be composed of high and low pressure vortices, upper (eastward) and lower (westward) jet streams ...
An Exactly Conservative Semi-Lagrangian Scheme (CIP–CSL) in One Dimension
Publisher: American Meteorological Society
Abstract: Two semi-Lagrangian schemes that guarantee exactly mass conservation are proposed. Although they are in a nonconservative form, the interpolation functions are constructed under the constraint of conservation of cell-integrated ...
Simultaneous Observations of Thin Humidity Gradients in the Lower Troposphere with a Raman Lidar and the Very High-Frequency Middle- and Upper-Atmosphere Radar
Publisher: American Meteorological Society
Abstract: Humidity is, among other things, a key parameter in the evolution of atmospheric dynamics and in the formation of clouds and precipitation through latent heat release. The continuous observation of its vertical distribution ...
Fatigue Failure Analysis of Cracks near the Sole Plate of a Half-Through Steel-Arch Bridge
Publisher: American Society of Civil Engineers
Abstract: A fractured bolt connecting the bearing and the stiffening girder of a half-through steel-arch bridge, with a main span length of 113 m, which was opened for public in September 1996, was found in October 2013 during ...
HRDI Observations of Mean Meridional Winds at Solstice
Publisher: American Meteorological Society
Abstract: High Resolution Doppler Imager (HRDI) measurements of daytime and nighttime winds at 95 km are used to deduce seasonally averaged Eulerian mean meridional winds during six solstice periods. These estimates are compared ...
