- Biserial correlation between vorticity field and precipitation: Rainfall diagnosis and prediction Nora E. Ruiz Ciencias de la Tierra vorticity Precipitation biserial correlation This work concerns the examination of a methodology of synoptic climatology, the biserial correlation technique, whichallows studying the relationship between atmospheric circulation and precipitation. The physical meaning of biserial correlationfields between variables representing synoptic-scale circulation, particularly vorticity fields, and local precipitation is explored.One purpose is to examine this approach used to link the large-scale circulation and the smaller-scale surface environment, whichseems to be simple, efficient and easy to interpret. An analysis based on biserial correlation configurations between 500 hPavorticity and precipitation takes into account anomalous vorticity gradients including curvature and shear effects to describe somemechanisms favoring the occurrence of rainfall. It is shown that anomalies in the curvature of synoptic systems are largely causingprecipitation. Daily precipitation at Córdoba, Argentina is used as an example to illustrate the results. The position of the cyclonicand anticyclonic anomaly centers and the position of the jet streams in association with precipitation may be clearly identified.The analysis is made extensive to heavier rainfall. 2002 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56841212 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.41
