This study investigates the relationship between crop yield anomalies of five major crops and meteorological indices on the pan-European scale. The crop yield data were obtained from Eurostat for the EU administrative Regions (NUTS). The meteorological indices (Standardized Precipitation Index, SPI, and Standardized Precipitation and Evaporation Index, SPEI) were derived from the WATCH Forcing Data for the administrative regions. Linear regression and the moving average were applied to de-trend the crop yield data. Pearson correlation analyses was carried out to explore the relationship between crop yield anomalies and SPI and SPEI. This study built upon an investigation on the relationship between crop yield losses and drought in Portugal.
