The MJO is most evident in the Indian and western Pacific Oceans, where it includes variations in wind, sea-surface temperature, cloudiness, and rainfall that, in turn, affect the intensity and break periods of the Asian and Australian monsoons. This study examines the relationship between the zonal oscillation of the western Pacific subtropical high (WPSH) and underneath sea surface temperature (SST) variation on a subseasonal time scale, associated with the persistent heavy rainfall (PHR) events over the middle and lower reaches of the Yangtze River valley (MLYRV) in China. The hypothesis emphasizes the importance of off-equator sea surface temperature and sea level pressure variations west of the dateline for initiating equatorial easterly winds over the far western Pacific. A data-based hypothesis is presented on the mechanism of the El Niño-Southern Oscillation (ENSO), a major determinant of interannual global climate variability.

The intraseasonal oscillation (convection) over the South China Sea and tropical western Pacific area is closely related to the summer rainfall (convection) in the southern China. western Pacific subtropical high (WPSH), tropospheric biennial oscillation (TBO), East Asian monsoon, tropical sea surface temperature (SST) anomaly, intensity index, western boundary index oscillations in the far western equatorial Pacific (1208–1408E) may originate from an air–sea interaction instability involving the mean seasonal wind cycle and evaporation.

OeyThe Philippines–Taiwan oscillation: monsoonlike interannual oscillation of the subtropical–tropical western North Pacific wind system and its impact on the ocean Journal of Climate, 25 (2012), pp. Y.-L. Chang, L.-Y. El Niño is a warming of surface waters in the eastern tropical Pacific Ocean. It can also interact with the Southern Oscillation, contributing to the intensity of an El Niño or La Niña event. Their relationship seems to be a seesaw feature, and this relationship resulting from the different pattern of convection in those two regions is caused by the differnt type of local meridional circulation. El Niño–Southern Oscillation (ENSO) is an irregularly periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics.
