                         coffee production, because of the freezing conditions related to 
                         them. The cooling is also felt in southern and with less intensity 
                         in the western Amazonia. We study three events of the winter of 
                         1994: 26 June, 9 July and 4 August. These frost events caused a 
                         sharp drop in the coffee production and similarly dramatic 
                         increases in the world coffee prices. We performe an study of 
                         synoptic and climatic aspects of these cold surges episodes by
