ABSTRACT
There are two basic approaches to modeling the impact of meteorological variability on crop yields. The physiological approach is an attempt to describe the detailed impact of meteorological variability on biological/physical processes that occur within a typical plant or a plant canopy. The statistical approach is an attempt to use a sample of yield data from an area (an experimental plot, a crop district, state, province, etc.) and a sample of weather data from the same area to produce estimates of coefficients in the model by some sort of regression technique.
