RISWavelet Analysis of the Convectively Coupled Equatorial Waves in the Wavenumber–Frequency Domain
Publisher: American Meteorological Society
Abstract: Wavelet analysis is performed on 31 yr (1975?2007, except 1978 and 1979) of daily outgoing longwave radiation data in the global equatorial region (15°S?15°N). Power spectra in the zonal wavenumber?frequency domain are ...
A Simple Empirical Model for Estimating the Intensity Change of Tropical Cyclones after Landfall along the South China Coast
Publisher: American Meteorological Society
Abstract: The intensity change of past (1976?2005) tropical cyclones that made landfall along the south China coast (110.5°?117.5°E) is examined in this study using the best-track data from the Hong Kong Observatory. The change in ...
Tropical Cyclone Motion in Response to Land Surface Friction
Publisher: American Meteorological Society
Abstract: Numerical experiments are performed with the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5) to study the effects of surface-moisture flux and friction over ...
Modeling the Effects of Land–Sea Roughness Contrast on Tropical Cyclone Winds
Publisher: American Meteorological Society
Abstract: The fifth-generation Pennsylvania State University?National Center for Atmospheric Research (PSU?NCAR) Mesoscale Model (MM5) is used to simulate tropical cyclone (TC) wind distribution near landfall. On an f plane at 15°N, ...
Tropical Cyclone Intensity in Vertical Wind Shear
Publisher: American Meteorological Society
Abstract: The structure and intensity changes of tropical cyclones (TCs) in environmental vertical wind shear (VWS) are investigated in this study using the fifth-generation Pennsylvania State University?National Center for Atmospheric ...
