Resumen
Descripción
Crop-yield weather modelling refers to the techniques which can be used operationally to determine the likely effect of weather on yields. Although the incidence of weather conditions on yields is well established, its quantitative assessment is not always straightforward: time series analyses of agricultural statistics show that the inter-annual variability1 of crop yields can be roughly subdivided into 3 components : trend, direct weather factors and indirect weather effects (pests, diseases, weed competition, etc.).
