[1] Mesoscale variability where the East Australian Current (EAC) separates from the coast is studied using sea surface temperature and surface velocity streamfunction observed by satellite and a regional numerical model. The mean circulation simulated by the model (the Regional Ocean Modeling System (ROMS)) is compared to a high‐resolution regional climatology, and the realism of the Cited by: SURFACE AND SYNOPTIC FEATURES OF LEADING AND PARALLEL STRATIFORM MESOSCALE CONVECTIVE SYSTEMS This study investigates the surface wind, pressure, and temperature patterns associated with mesoscale convective systems meeting the classification of leading or parallel stratiform.

This paper is based on the experimental observation. The micro-topography characteristics of electrical discharge machining (EDM) surface were studied. The results show that the EDM surface is made up of three-dimensional craters and hard protrusions overlapped alternately which distribute randomly and non-directionally.

CHAPTER 9 STUDY ON SURFACE TOPOGRAPHY INTRODUCTION This chapter deals with studies on surface topography. Surface topography literally means ‘the study or detailed description of the surface feature or a region’. Surface integrity involves the study and control of both surface roughness or surface topography, and surface metallurgy.

Lilly. Numerical simulation is an increasingly important tool for improving our un-derstanding of a wide range of atmospheric phenomena.

The first part of this book. The National Weather Service Forecast Office in Miami, FL, is your source for the most complete weather forecast and weather related information on the web. This new textbook seeks to promote a deep yet accessible understanding of mesoscale-convective processes in the atmosphere.

Mesoscale-convective processes are commonly manifested in the form of thunderstorms, which are fast evolving, inherently hazardous, and can assume a 5/5(2).

The prevailing mesoscale model MM5 (V3) is used to simulate a heavy rain case caused by interaction between a move-in front and topographical heterogeneities on Taiwan Island. It is found that both thermodynamic and dynamic fields along the front are heterogeneous in time and space. Mesoscale studies incorporating topography and surface wind.

However, when a mesoscale topography is incorporated, the spatial scale of the quasi-final state vortex reduces, and the relative vorticity at the center of the vortex and the local maximum wind.

Mesoscale meteorology is the study of weather systems smaller than synoptic scale systems but larger than microscale and storm-scale cumulus systems.

Horizontal dimensions generally range from around 5 kilometers to several hundred kilometers. Examples of mesoscale weather systems are sea breezes, squall lines, and mesoscale convective complexes. Vertical velocity often equals or exceeds. Climatological features of the surface wind on diurnal and seasonal time scales over a yr period in an area of complex terrain at Dugway Proving Ground in northwestern Utah are analyzed, and potential synoptic-scale, mesoscale, and microscale forcings on the surface wind are by: 1.

The wind field data on an isobaric surface of hPa (i.e. an altitude of about m) was used in this investigation. In case 1, horizontal wind is strong as a whole and strong ascending flows occur on the windward side of mountains as shown in the centre figures.

In case 2, horizontal. The test specimens for ring compression test and extrusion were made from commercially pure aluminium bars.

Rings were made with geometry commonly used for ring test, as shown in Fig. 1(a) and cylindrical samples were used for extrusion, as in Fig. 1(b).The end faces of the rings and side surfaces of the cylindrical pieces were finished by either EDM, polishing, turning or by: Based on the studies of Enagonio et al.

Model and experiment design Author: Zhexian Luo, Yun Gao. This book provides an overview of several components of mesoscale modeling: boundary conditions, subgrid-scale parameterization, moisture processes, and radiation.

Mesoscale science encompasses the observation, understanding, and control of these intermediate-scale architectures and phenomena [1]. The systematic investigations of mesoscale architectures and phenomena — ubiquitous as the hierarchical "staircase" connecting atoms to bulk materials — are somewhat in their infancy, but offer unprecedented.

Problems of the Mesoscale • Synoptic observation systems have horizontal resolutions of km and 1 hour at the surface and km and 12 hours aloft and are clearly inadequate to capture all but the upper end of the meso.

• The dynamics of mesoscale disturbances contain important non-balanced or transient features that propagate rapidly. Introduction [2] The mesoscale variability is the dominant signal in the ocean circulation. Eddies, vortices, fronts, jets, meanders, rings and filaments can be observed almost everywhere.

Thus, resolving the mesoscale variability is crucial to correctly understand the dynamics of the ocean circulation and to estimate the associated heat transport, even at climatic scales [Wunsch, ].Cited by: On the Mesoscale Structure of Surface Wind and Pressure Fields near Tornadic and Nontornadic Cold Fronts MATTHEW R.
