Viewing Weather as the Expression of Climate.

It is common when speaking colloquially to describe climate as the average weather, which implies weather is the driver and climatic averages are a passive by-product of it, but it is useful to reframe this toward weather being the "expression" of climate. That is, a region's climate defines the range of weather it might experience (including the extent and frequency of extremes). In this framing, weather is driven by a region's climate. A changing climate then, necessarily, is experienced as a change in local weather events--often most visibly through changes in the extent or frequency of extreme weather. [ABSTRACT FROM AUTHOR]
