The Dew-Point Anchor Hypothesis (DPAH) emphasizes the critical role of dewpoint-controlled Lifting Condensation Level (LCL) in anchoring intense low-level updrafts and vorticity stretching — a key ingredient for tornado genesis. This deposit applies DPAH to tornado environments, with a focused case study of the 20 May 2013 Moore, Oklahoma EF5 tornado. Key elements include: Thermodynamic profiles comparing tornadic moist inflow (very low LCL), rear-flank downdraft (RFD, dry air), and non-tornadic reference environments Simplified Significant Tornado Parameter (STP)-like composite using DPAH LCL, surface dewpoint, and low-level shear proxy Markov model for storm mode transitions (ordinary cell → supercell → tornadic supercell) Consolidated master script integrating profiles, STP-like diagnostics, and probabilistic transitions Results show that the Moore EF5 environment produced exceptionally low LCL heights and a high DPAH-STP-like value, consistent with its violent outcome. All code is MIT-licensed and executable with standard scientific Python libraries.
