Moisture recycling

In hydrology, moisture recycling or precipitation recycling refer to the process by which a portion of the precipitated water that evapotranspired from a given area contributes to the precipitation over the same area. Moisture recycling is thus a component of the hydrologic cycle. The ratio of the locally derived precipitation (${\displaystyle P_{L}}$) to total precipitation (${\displaystyle P}$) is known as the recycling ratio, ${\displaystyle \rho }$: ${\displaystyle \rho =P_{L}/P}$.
