This reduction in column radiative cooling—likely driven by the local invigoration of moist convection Fig. Rather, large-scale circulation and humidity are intimately linked—that is, on the spatiotemporal scales important to the MJO, wherein temperature variations are relatively small Charney ; Raymond ; Sobel et al. The Madden—Julian oscillation MJO; Madden and Julian , dominates tropical intraseasonal 20—90 day variability and influences global weather e. Cotturone, : Multiscale variability of the atmospheric mixed layer over the western Pacific warm pool. Part I: Convective signals. It is hypothesized that the diurnal cycle and mesoscale cloud organization characteristic of the preonset stage of the MJO represent two manners in which local processes promote more vigorous daily-mean column moistening than would otherwise occur. Namely, the diurnal cycle of convective clouds dominates temporal variations of column humidity during the preonset stage Fig. All fields have been smoothed using a min running mean. The vertical dotted lines indicate local noon.
