WebOct 1, 2024 · The initial stage of the tornado may exhibit a descending reflectivity core (DRC) pattern ( Rasmussen et al. 2006; Byko et al. 2009 ). The DRC typically occurs prior to the development of the hook echo. The DRC signatures can be used to detect tornadogenesis. DRCs may or may not be associated with tornadic storms.
