Influences of Intraseasonal Oscillations on the Clustering of Tropical Cyclone Activities over the Western North Pacific during Boreal Summer
大气季节内振荡对夏季西北太平洋热带气旋群发性的影响

The NCEP/NCAR reanalysis, outgoing longwave radiation (OLR) and tropical cyclone datasets are employed to investigate the clustering characteristics of tropical cyclone activities over the western North Pacific from June to September in 1991 and their associations with intraseasonal oscillations (ISOs), in which tropical cyclone data refer to the best tracks from the Shanghai Typhoon Institute of China Meteorological Administration. Tropical convective activities are found to exhibit an intraseasonal oscill...
