New generation of satellite-derived ocean thermal structure for the western north pacific typhoon intensity forecasting
Ocean thermal structure is critical for the intensity change of tropical cyclones (TCs). It has been operationally derived from satellite altimetry for TC forecasting and research. The existing derivation is, however, based on a simple two-layer method; as a result, only two isotherms can be obtained to coarsely characterize the subsurface ocean thermal structure. Improvement on the vertical re...
متن کاملDecadal variations of intense typhoon occurrence in the western North Pacific
The causes of one of the two major oscillation periods, 16–32 years, identified through a wavelet analysis, of the time series of the frequency of intense typhoon (categories 4 and 5 in the Saffir–Simpson scale) occurrence for the period 1960–2005 in the western North Pacific (WNP) is studied in this paper. By dividing this period into sub-periods during which the frequency of intense typhoon o...
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 کاملRegional modelling of the western Pacific typhoon season
An ensemble of typhoon events was examined to detect systematic skills and deficiencies of regional atmospheric models in dynamical downscaling these extreme weather phenomena from global reanalyses data. A regional atmospheric model hindcast was computed for the typhoon season 2004 for SE Asia and the western North Pacific. Global reanalyses data were dynamically downscaled to a grid resolutio...
متن کاملNorthwestern Pacific typhoon intensity controlled by changes in ocean temperatures
Dominant climatic factors controlling the lifetime peak intensity of typhoons are determined from six decades of Pacific typhoon data. We find that upper ocean temperatures in the low-latitude northwestern Pacific (LLNWP) and sea surface temperatures in the central equatorial Pacific control the seasonal average lifetime peak intensity by setting the rate and duration of typhoon intensification...
