Short summary
The diurnal cycles of precipitation are not phase-locked to daily insolation; rather, their occurrences are associated with propagating systems. The early morning precipitation (EMP) events are distinctly characterized by large mean amplitudes and randomly distributed phases also marked by strong connectivity between precipitation systems over land and ocean. This implies that, even for a 24 h lead time, probabilistic forecast may be necessary to assess the hazard of heavy precipitation.
