Abstract
The Tornado Resonance‑Detection & Early‑Action Module (TRD‑EAM) is a standalone, open‑hardware tornado‑warning device that uses:
-
ARPN infrasonic sensing
-
pressure‑wave harmonics
-
vorticity resonance detection
-
temperature inversion sensing
-
humidity‑wave detection
-
EM field anomaly detection
-
multi‑node coherence
-
CICIS tornado logic
-
ADEP tornado alert packets
to provide 10–30 minutes of tornado precursor warning.
TRD‑EAM is designed to be:
-
printed on any 3D printer
-
assembled with basic tools
-
powered by TEHL (no batteries)
-
flashed with open firmware
-
deployed anywhere
-
tested tomorrow
This module is the physical tornado‑warning device that completes GCI‑500.
