Potential users of seasonal to interannual climate predictions are often interested in forecasts of seasonal rainfall totals at the local scale. In addition, within-season rainfall characteristics, such as rainfall occurrence frequency and intensity can be of particular concern; the frequency and length of dry spells, for example, are important to agriculture Ingram et al. Seasonal mean rainfall can be decomposed as the product of daily rainfall occurrence frequency and average daily rainfall intensity.
In physics, coherence means a property of waves — coherent waves are able to interfere as they have a constant phase relation. Some light sources such as lasers already have a high spatial and temporal coherence due to their design. For some years such sources are also available for atoms; they are based on Bose-Einstein condensates and are able to emit coherent matter waves. However, for large molecules we often have to work with incoherent thermal sources.

Coherent Optics pp Cite as. In optics, the original sense of the word coherence was attributed to the ability of radiation to produce interference phenomena. Today, the notion of coherence is defined more generally by the correlation properties between quantities of an optical field. Usual interference is the simplest phenomenon revealing correlations between light waves. Unable to display preview. Download preview PDF. Skip to main content.

However, no clear distinction between the spatial and temporal phonon coherence has been accounted for and a formalism that quantifies.
