Here is a comprehensive radar list of each Violent (EF4+) tornado via NEXRAD/other radar! For some disclaimers:
Here is a comprehensive radar list of each Violent (EF4+) tornado via NEXRAD/other radar! For some disclaimers:
-The lowest ideal tilts were used in most radar images (if not it will be specified in notes).
-The lowest ideal tilts were used in most radar images (if not it will be specified in notes).
- Forensic radar details included such as: VROT, Delta Velocity (ΔV), maximum Normalized Rotation (NROT) reliably in closest proximity to tornado, observed storm motion vector (SMV), and radar sites used.
-If radar site includes Dual Polarization data (post ~2011), Tornadic Debris Signature height (TDS) and ZDR peak width in nautical miles at freezing level (ZDR0) prior to tornadogenesis will be included.
-Path length, width, injuries/deaths info is obtained through Tornado Archive
-Products used: Base Reflectivity, Base Velocity, Spectrum Width (on older data), ZDR0, NROT.
-A good page to reference for analog cases (specifically the interesting ZDR0 width correlation in plausible tornado intensity found in recent research).
-STILL WIP!
