The all-important Madden-Julian Oscillation (MJO) wave is forecast to redevelop in the coming days between tropical Africa and Central Indian Ocean. This may re-invigorate the Indian monsoon, according to the Australian Bureau of Meteorology, a widely respected MJO tracker. The MJO wave passes periodically from West to East over the Indian Ocean and is loaded with significant implications for weather under its footprint. The Arabian Sea and the Bay of Bengal, which lie just North of the Indian Ocean, are also impacted in the bargain, which in turn determines the performance of the Indian monsoon. Monsoon has been witnessing a slightly weak patch after a promising start and the MJO forecast indicates at a revival in rainfall in coming days.
