摘要：
A radar-based analysis of known tornadic mesocyclones associated with two mature tropical cyclones was carried out. These two cyclones are Tropical Storm Gordon (1994) and Hurricane Allison (1995). Analyses of storm-scale reflectivity and velocity signatures are conducted in the context of establishing preliminary critical criteria for use in the tornado detection and warning process. Important characteristics include the detection of discrete, small-diameter echoes collocated with storm-relative rotational velocities and other rotational features. Several recommendations are given to assist operational radar meteorologists with the task of detecting outer rainband tornadoes.
