Western 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 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 کاملForced and internal variability of tropical cyclone track density in 1 the western North Pacific
6 Forced interannual-to-decadal variability of annual tropical cyclone (TC) track density in 7 the western North Pacific between 1979-2008 is studied using TC tracks from observations 8 and simulations by a 25-km-resolution version of the GFDL High-Resolution Atmospheric 9 Model (HiRAM) that is forced by observed sea surface temperatures (SSTs). Two modes 10 dominate the decadal variability: a ...
متن کاملSatellite-Derived Tropical Cyclone Intensity in the North Pacific Ocean Using the Deviation-Angle Variance Technique
The deviation-angle variance technique (DAV-T), whichwas introduced in theNorthAtlantic basin for tropical cyclone (TC) intensity estimation, is adapted for use in the North Pacific Ocean using the ‘‘best-track center’’ application of the DAV. The adaptations include changes in preprocessing for different data sources [Geostationary Operational Environmental Satellite-East (GOES-E) in the Atlan...
متن کاملInterannual Variation of Multiple Tropical Cyclone Events in the Western North Pacific
The interannual variability of occurrence of multiple tropical cyclone (MTC) events during June–October in the western North Pacific (WNP) was examined for the period 1979–2006. The number of the MTC events ranged from 2 to 9 per year, exhibiting a remarkable year-to-year variation. Seven active and seven inactive MTC years were identified. Compared to the inactive years, tropical cyclone genes...
