=== ### === * The latent heat cooling impact. * The corrected sublimation rate with proper diffusion constant. * The vapor pressure values from Murphy & Koop (2005) and Clausius-Clapeyron. * The mass flux equation (dm/dtdm/dtdm/dt) and its correct dependency on DDD, ΞP\Delta PΞP, rrr, etc. ===== - I originally overestimated the sublimation mass rate by about 1β2 orders of magnitude (~10β»ΒΉβ° kg/s instead of ~10β»ΒΉΒ² kg/s). ===== * I originally understated the importance of cooling β it's first-order, not a tiny correction. * I underestimated D at 10 km altitude β itβs around 2.5Γ10β»β΄ mΒ²/s, not 2.1Γ10β»β΅ mΒ²/s (that was closer to sea level). * Their dynamic RHi adjustment idea is correct β as ice crystals form and grow, they rapidly deplete vapor locally. ===== - Their tone is harsh, but the math is generally sound. ===== * Their vapor pressure values are slightly rounded differently than Murphy & Koop tabulated values β but they are within acceptable atmospheric physics tolerances (~5β10% differences). * Some of their timescale claims (like 33 s at RHi 160%) assume "static" RHi β but dynamically, the wake environment collapses RHi faster. (Which they admit later.) β Thus, the ''physics structure'' Grok uses is correct. β The ''corrections to the numerical details'' are valid and verifiable. β The ''core outcome'' matches what we already knew: even after all corrections, sunlit crystals sublimate very quickly.
