The Tunguska Humidity-Shield Hypothesis

The Tunguska Humidity-Shield Hypothesis proposes that the 1908 Tunguska explosion was shaped not only by the incoming meteoroid but also by patchy humidity structures in the lower Siberian atmosphere. These humidity gradients acted as shock-refraction boundaries, altering blast propagation and resolving several long-standing anomalies including the butterfly fall pattern, upright trees at the hypocenter, sharp burn edges, spiral-vector tree fall, weak seismic signals, and multiple acoustic booms. This model is based on standard atmospheric physics and interprets the event as an interaction between extraterrestrial energy and terrestrial atmospheric structure. The paper outlines testable predictions including humidity reconstruction, CFD blast simulation, soil pressure analysis, and acoustic modeling.
