Abstract

Deep moist convection is an element of cloud disturbances such as Madden-Julian oscillation (MJO), tropical cyclones (TCs), mid-latitudinal low depressions (MDL), and fronts (FRT). However, differences in convection characteristics in disturbances remain unclear. We first clarified the statistical features of the convection (structure, intensity, and environmental parameters) in various disturbances simulated by a global simulation with a sub-kilometre grid spacing. The convection in MJO (TC) was tall with a strong (weak) upward motion, and was driven by large convective available potential energy (strong low-level convergence). The convection in MDL and FRT was shorter and characterized by a strong vertical wind shear.
