Short summary

Gravity waves from deep convection along with terrain and coastal effects control the development and movement of squall lines that affect the diurnal cycle of rainfall over New Guinea and its northern coast. Days with offshore propagating systems are governed by background conditions (more mid-tropospheric moisture, CAPE, and low-level convergence) as opposed to days without offshore propagation. Our results shed some light on the physics and dynamics of Maritime Continent organised convection
