A Study on Surface Evaporation in Liaoyang Based on Grey Theory

Abstract:

At present, there are mainly two methods to forecast the quantity of surface evaporation: one is by time series analysis, another is by climate models. This paper established models to simulate the surface evaporation in Liaoyang based on grey theory, and developed a grey forecasting software for surface evaporation using Visual Basic. From the annual depreciation from 1998 to 2010 in Liaoyang station in Liaoning Province, a grey forecasting model was established, which was then used to predict the quantity of surface evaporation in Liaoyang from 2011 to 2015.
