Abstract

Key Points:• Tropical cyclone diurnal pulses are successfully simulated, showing column-spanning signatures consistent with observations• Diurnal pulses propagate broadly consistent with classical gravity-wave theory, with small deviations likely driven by latent heating• Diurnal pulses are more frequent at night, likely due to constructive interference with the cyclone's diurnal circulation
