Coherent Precipitation and Strengthening in Compositionally Complex Alloys: A Review [PDF]
Entropy, 2018 High-performance conventional engineering materials (including Al alloys, Mg alloys, Cu alloys, stainless steels, Ni superalloys, etc.) and newly-developed high entropy alloys are all compositionally-complex alloys (CCAs).

The Globally Coherent Pattern of Autumn Monsoon Precipitation [PDF]
Journal of Climate, 2021 AbstractOver most tropical land areas, the annual peak in precipitation occurs during summer, associated with the local monsoon circulation. However, in some coastal regions in the tropics the bulk of annual precipitation occurs in autumn, after the low-level summer monsoon westerlies have abated.

Partially Coherent Backscatter in Radar Observations of Precipitation [PDF]
Journal of the Atmospheric Sciences, 2010 Abstract Classical radar theory only considers incoherent backscatter from precipitation. Can precipitation generate coherent scatter as well? Until now, the accepted answer has been no, because hydrometeors are distributed sparsely in space (relative to radar wavelength) so that the continuum assumption used to explain coherent scatter ...

Coherent precipitation strengthening by/in LI2-ordered phases
Journal de Physique III, 1991 Microstructural characteristics of (i) the alloys strengthened by precipitation of a coherent LI2-ordered phase and (ii) the LI2-ordered alloys strengthened by the precipitation of coherent disordered phase are reviewed with particular emphasis on the effects of volume fraction and morphology of second phase.

Thermodynamic model for lattice point defect-mediated semi-coherent precipitation in alloys
Communications Materials, 2021 Precipitation of secondary phases in a crystalline matrix often leads to the loss of coherency at the phase boundary. Here, a thermodynamic model for precipitation is presented that takes into account the role of lattice point defects on the ...

A Coherent Approach to Evaluating Precipitation Forecasts over Complex Terrain
Atmosphere, 2022 Precipitation forecasts provided by high-resolution NWP models have a degree of realism that is very appealing to most users of meteorological data. However, it is a challenge to demonstrate whether or not such forecasts contain more skillful information

Coherent Modelling of Backscatter and Propagation of Precipitation [PDF]
, 2002 In order to improve knowledge about scattering processes and their effects on the backscattered signal, accurate modelling of radar backscatter is required. In this paper we present a stochstic, coherent and fully-polarimetric scattering model which simulates the propagation of an electromagnetic wave through a medium containing raindrops of various ...

Large-scale circulation shapes the spatial organization of anomalous precipitation over Northern Jiangsu [PDF]
iScienceSummary: Anomalous precipitation events often exhibit coherent spatial organization rather than isolated intensity extremes, reshaping regional flood risk in subtropical monsoon zones.
