This Concept Map, created with IHMC CmapTools, has information related to: Tornados, Feeder bands associated with Tropical storms, Tornado development progresses to "Corkscrew" Spin (i.e., faster and tighter), A combination of factors i.e., Moderate to strong instability, Severe thunderstorms which involve Vertical wind shear, Mixing, shearing, and lift occur to a greater degree Inland, Vertical wind shear lead to Tornado development, Divergence aloft causes Convergence at the surface, Low-level jet moving south to north is a Wind that is perpendicular to an upper- level jet max, Causal dynamics include Moderating factors, Severe thunderstorms i.e., Tropical storms, Tornados in the Gulf Coast Region have Doppler Radar (NEXRAD) signatures, Severe thunderstorms i.e., Air mass thunderstorms, Convergence at the surface create Moderate to strong instability, Doppler Radar (NEXRAD) signatures are "Horseshoe" and "hook echo" in Base reflectivity, Low-level jet moving south to north pumps Warm, moist air, Divergence aloft create Moderate to strong instability, Rotation lead to Tornado development, Doppler Radar (NEXRAD) signatures are "Gate-to-gate" in Relative velocity, Causal dynamics are Very difficult to forecast, Tornados in the Gulf Coast Region are more likely in Late Winter to early Spring
