Wavelets in Geophysics by Efi Foufoula-Georgiou, Praveen Kumar

By Efi Foufoula-Georgiou, Praveen Kumar

Functions of wavelet research to the geophysical sciences grew from Jean Morlet's paintings on seismic signs within the Nineteen Eighties. Used to notice indications opposed to noise, wavelet research excels for transients or for spatiallylocalized phenomena. during this fourth quantity within the renown WAVELET research AND ITS functions sequence, Efi Foufoula-Georgiou and Praveen Kumar start with a self-contained evaluate of the character, energy, and scope of wavelet transforms. The 11 originalpapers that persist with during this edited treatise exhibit how geophysical researchers are utilizing wavelets to research such assorted phenomena as intermittent atmospheric turbulence, seafloor bathymetry, marine and different seismic info, and circulation in aquifiers. Wavelets in Geophysics will make informative studying for geophysicists looking an updated account of ways those instruments are getting used in addition to for wavelet researchers trying to find principles for functions, or perhaps new issues of departure.

  • Includes twelve unique papers written through specialists within the geophysical sciences
  • Provides a self-contained evaluate of the character, strength, and scope of wavelet transforms
  • Presents purposes of wavelets to geophysical phenomena corresponding to: the pointy occasions of seismic information, lengthy reminiscence procedures, similar to fluctuation within the point of the Nile, A constitution retaining decomposition of turbulence signals

K. Gamage Abstract. Coherent structures in velocity and temperature in the atmospheric boundary layer account for a large portion of flux transport of scalars such as momentum, heat, trace chemicals and particulates. Generally, coherent structures are bounded by zones of concentrated shear in velocity or temperature fields. We develop techniques based on the wavelet transform to provide a signal decomposition which preserves coherent structures. The decomposition is used to separate the signal into two components, one of which contains the important structures as defined by the characteristics of the transform.
