What Percentage of Western North Pacific Tropical Cyclones Form within the Monsoon Trough?
It is frequently stated that 70%–80% of western North Pacific tropical cyclones form ‘‘within the monsoon trough,’’ but without an objective definition of the term. Several definitions are tested here. When the monsoon trough (MT) is defined as the contiguous region where long-term (1988–2010) mean July– November 850-hPa relative vorticity is positive, 73% of all July–November tropical cyclones...

متن کاملInterannual Variability of Summer Monsoon Onset over the Western North Pacific and the Underlying Processes
Climatological summer monsoon onset over the South China Sea (SCS) and the western North Pacific (WNP) (defined as the region of 108–208N, 1208–1608E) displays three distinct stages. Around mid-May, monsoon rain commences in the SCS and the Philippines. In early to mid-June, the monsoon rain extends to the southwestern Philippine Sea. After mid-July, the rainy season starts in the northeastern ...
متن کاملWestern North Pacific Typhoons with Concentric Eyewalls
This study examines the intensity change and moat dynamics of typhoons with concentric eyewalls using passive microwave data and best-track data in the western North Pacific between 1997 and 2006. Of the 225 typhoons examined, 55 typhoons and 62 cases with concentric eyewalls have been identified. The data indicate that approximately 57% of category 4 and 72% of category 5 typhoons possessed co...
متن کاملHydrographic Processes Driven by Seasonal Monsoon System Affect Siphonophore Assemblages in Tropical-Subtropical Waters (Western North Pacific Ocean)
This work is a part of the Taiwan Cooperative Oceanic Fisheries Investigation, the first large scale hydrographic and plankton survey around Taiwan (21-26°N, 119-123°E). The present study examined the influence of hydrodynamic and biological variables driven by monsoon system on the siphonophore assemblages through an annual cycle in 2004. Calycophorans, namely Chelophyes appendiculata, Diphyes...
