Developing versus Nondeveloping Disturbances for Tropical Cyclone Formation. Part II: Western North Pacific*
Global daily reanalysis fields from the Navy Operational Global Atmospheric Prediction System (NOGAPS) are used to analyze Northern Hemisphere summertime (June–September) developing and nondeveloping disturbances for tropical cyclone (TC) formation from 2003 to 2008. This is Part II of the study focusing on the western North Pacific (WNP), following Part I for the North Atlantic (NATL) basin. T...
متن کاملDeveloping versus Nondeveloping Disturbances for Tropical Cyclone Formation. Part I: North Atlantic*
This study investigates the characteristic differences of tropical disturbances that eventually develop into tropical cyclones (TCs) versus those that did not, using global daily analysis fields of the Navy Operational Global Atmospheric Prediction System (NOGAPS) from the years 2003 to 2008. Time filtering is applied to the data to extract tropical waves with different frequencies. Waves with ...
متن کاملThe 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 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 کاملAnalysis of Tropical Cyclogenesis in the Western North Pacific for 2000 and 2001*
High-resolution satellite data and NCEP–NCAR reanalysis data are used to analyze 34 tropical cyclone (TC) genesis events in the western North Pacific during the 2000 and 2001 typhoon seasons. Three types of synoptic-scale disturbances are identified in the pregenesis stages. They are tropical cyclone energy dispersions (TCEDs), synoptic wave trains (SWTs) unrelated to preexisting TCs, and easte...
