A Minimal Electrodynamic Hydrology Model: A Prognostic Charge-Bucket Framework for Cloud Microphysics (v9)

“The Charge Bucket” presents a minimal electrodynamic hydrology model in which cloud electrification is treated as a prognostic reservoir: each droplet’s rapid freezing—driven by exclusion-zone microphysics—injects a discrete quantum of charge into a columnar “bucket,” which then accumulates until a prescribed threshold triggers a discharge event analogous to lightning. After each discharge, the bucket resets, and the transient Joule heating and conductivity feedbacks subtly modulate local buoyancy and microphysical processes. By varying ambient conductivity to simulate geomagnetic- and solar-wind-driven ionization changes, this framework links millisecond-scale EZ charge injection directly to storm-scale flash statistics, offering a scalable, mechanistic bridge between laboratory microphysics and observed global lightning variability.
