Resumo:  The Geoviticulture Multicriteria Climatic Classification System (MCC System) has been employed in different regions of the world for grapevine zoning studies. The Dryness Index (DI) is one of the three MCC indices and its calculation is based on a soil water balance approach. However, other climatic indices are still been used for the same purpose. One of them is the Vineyard Water Indicator (VWI). This index represents the ratio between the total rainfall and vineyard water requirement during the productive period of the culture. When compared to DI, the VWI has a simpler calculation methodology. Therefore, the aim of the present study was to establish a model to estimate DI based on VWI values. Climate data of 82 winegrowing regions in 18 countries were used. Four regression models were evaluated: linear, quadratic, logarithmic and the Mitscherlich model. ...
