Abstract: This study demonstrates the multiscale nature, from synoptic to intraseasonal time scales, of the atmospheric flow in the tropical western North Pacific. The multiscale features include intraseasonal oscillations (ISO), ...

Abstract: The impact of tropical perturbation on the extratropical wave activity in the North Pacific in the submonthly time scale is demonstrated here. Previous studies identified a tropical cyclone (TC)/submonthly wave pattern, ...

Abstract: A composite of 10 cases of zonal wind maxima at 200 hPa over the subtropical region stretching from Australia to the central Pacific is examined for the six-month period, November 1984-April 1985. This region is unique in ...

Abstract: his study introduces a modified Pacific?Japan (PJ) index that exhibits a substantial periodicity of 5?16 days in the East Asian summer monsoon region. The quasi-periodic fluctuations of the PJ index can indicate changes ...

Abstract: n this study, the circulation patterns of the summer monsoon associated with monsoon rainfall in southern Taiwan were analyzed and two types of monsoon patterns were defined. The first type was characterized by a broad low ...

Abstract: The behavior of subtropical jet streaks over the Australian?South Pacific region is investigated for four consecutive 6-month summer seasons, November to April, during the period 1985?89. The study is an extension of a ...

Abstract: The main objective of this study is to obtain a better understanding of the upper-tropospheric subtropical westerly wind maxima over the Australian?South Pacific region in the summer half of the year, which have been ...

Abstract: ropagation and maintenance mechanisms of the tropical cyclone/submonthly wave pattern in the western North Pacific are explored. The wave pattern exhibited an equivalent barotropic structure with maximum vorticity and ...
