ResumoAn attempt is made to relate the occurrence and the location of Tornado activity to areas of intense surface warm advection as indicated by the isobars and isotherms on the sea level chart. The degree of cross-isotherm flow is classified by the packing of the thermal field and the temperatures in it along with the strength and direction of flow as indicated by the isobars to determine short range forecasting patterns. The method presented is limited in that it is not applicable to all tornado situations and is offered as a supplementary technique which could serve to raise the confidence level of short range tornado forecasts based on upper air parameters.
