Thank you for your continued support, and we look forward to your feedback on this latest installment.
Prior to Part 4, wind was a continuous, smooth field. That was unrealistic. Severe weather is defined by discontinuities. Version 0.4 Part 4 introduces Explicit Downburst Modeling (EDM) . This work was supported by the Open Atmospheric
When the rain-cooled downdraft (a product of evaporative cooling and drag) exceeds a vertical velocity of 5 m/s, the simulation spawns a microburst object. These are not particles; they are temporary pressure anomalies that descend at speeds up to 30 m/s.
Key features of EDM:
Realism note: In testing, a Part 4 simulation of the 1999 Bridge Creek–Moore tornado outbreak produced an outflow boundary that spawned nine separate supercell-like structures over a virtual 14-hour period. That is computational meteorology, not animation.
