The Pacific Meridional Mode and the Occurrence of Tropical 1 Cyclones in the Western North Pacific
30 This study investigates the association between the Pacific Meridional Mode (PMM) 31 and tropical cyclone (TC) activity in the western North Pacific (WNP). It is found that 32 the positive PMM phase favors the occurrence of TCs in the WNP while the negative 33 PMM phase inhibits the occurrence of TCs there. Observed relationships are 34 consistent with those from a long-term preindustrial co...
متن کاملImplications of the Observed Relationship between Tropical Cyclone Size and Intensity over the Western North Pacific
Tropical cyclone (TC) size, usually measured with the radius of gale force wind (34 kt or 17m s), is an important parameter for estimating TC risks such as wind damage, rainfall distribution, and storm surge. Previous studies have reported that there is a very weak relationship between TC size and TC intensity. A close examination presented here using satellite-based wind analyses suggests that...
متن کاملWestern North Pacific Tropical Cyclone Intensity and ENSO
The influence of the El Niño–Southern Oscillation (ENSO) on tropical cyclone intensity in the western North Pacific basin is examined. Accumulated cyclone energy (ACE), constructed from the best-track dataset for the region for the period 1950–2002, and other related variables are analyzed. ACE is positively correlated with ENSO indices. This and other statistics of the interannually varying tr...
متن کاملWhat 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 کاملEffect of ENSO and the MJO on Western North Pacific Tropical Cyclones
Prior work has suggested that Rossby wave accumulation in the lower troposphere may be an important mechanism for the development of synoptic-scale disturbances in the western north Pacific in northern summer. This work examines the intraseasonal and interannual variability of wave accumulation by computing the barotropic wave activity flux divergence at 850 hPa for different phases of the Madd...
