The 10- to 15-day time scale is closely related to the intraseasonal (or 30-60 day) oscillations that propagate from the Indian Ocean to the western Pacific along the equator all year round. Large convective complexes known as supercloud clusters (SCC) are found to organize in the 10- to 15-day time scale, especially over the open, warm water of the western/central Pacific (160°E to 180°). The SCCs generally propagate eastward. The SCC is found to be made up of several well-organized cloud clusters, which are generated at 2- to 3-day intervals and propagate in the opposite direction to the SCC. The diurnal variation is most pronounced over the maritime continent, although significant amplitudes are also found over the open ocean. -from Authors |
