Dew-Point Anchor Hypothesis (DPAH): Application to Atlantic Hurricanes – Master Workflow, Rapid Intensification, and Radial Structure Analysis of 2018 Hurricane Michael

The Dew-Point Anchor Hypothesis (DPAH) posits that the lifting condensation level (LCL) anchored by surface dewpoint is the primary thermodynamic control for convective organization. This deposit extends DPAH to Atlantic tropical cyclones, with a detailed case study of 2018 Hurricane Michael.

Key Components:

• Vertical thermodynamic profiles (eye vs eyewall) with stratospheric subsidence in the eye
• Intensity sensitivity and Rapid Intensification (RI) modeling
• Time-track analysis across three distinct surface environments: Gulf of Mexico → Florida Land → Atlantic Ocean
• Radial Markov chain model (Eye ↔ Eyewall ↔ Rainbands) coupled with LCL profiles
• Full consolidated master script (RunMaster_Hurricane.pv)

The modelling reproduces observed behaviour: very low LCL and high eyewall probability during RI over warm Gulf waters, sharp LCL rise and eyewall suppression at landfall, and partial recovery over the Atlantic.

This work complements the earlier Monsoon/Thar Desert deposit and demonstrates DPAH’s versatility across dry sensible-heat and moist latent-heat driven systems.
