Summary
Pioneered by Madden and Julian (1971, 1972), the intraseasonal oscillation (ISO) did not receive much attention until mid to late 1980s. Since then there has been a surge of studies based on observations, numerical modeling, and theoretical treatment of its phenomenon. According to the two seminal papers by Madden and Julian, the ISO is marked by a planetary zonal wavenumber one structure and a fast (~5 m s–1) eastward-propagating feature from the Indian Ocean to the central Pacific along the equator within a time window of 40–50 days. Associated with the ISO deep convections are fluctuations in surface pressure and zonal wind component at both lower and upper troposphere. A slower poleward propagation in the Pacific is also found. The discovery of tropical intraseasonal variability can be traced back in Chinese literature to Xie et al. (1963), who published eight years prior to the first paper by Madden and Julian (1971). Because of its publication in a non-English journal, it has eluded the international research community working in the field (Li et al., 2018).
