    Advanced data processes of some meteorological parameters
    (CRC Press, 2005) Tokgozlu A.; Aslan Z.
    This chapter provides a case study on the application of curve fitting and harmonic analysis for some meteorological parameters in Isparta. Future projections of air temperature, pressure, rainfall, rate and wind speed data based on polynomial, final intervals and trigonometric functions have been evaluated for the study area. To define the model parameters, data observed in Isparta between 1929-2001 have been considered. Results of the harmonic analysis (Fourier series) and analysis of amplitude and phase values explain the small-, meso-, and large-scale effects on the parameters. The results of this chapter are evaluated and compared with wavelet analysis for this pilot project. This study has a key role to define the climate changing effects on meteorological parameters. © 2006 by Taylor & Francis Group, LLC. All rights reserved.

    Wavelet analysis of tropospheric and lower stratospheric gravity waves
    (CRC Press, 2005) Oğuz O.; Can Z.; Aslan Z.; Siddiqi A.H.
    To define the wave packets, wavelet analysis has been applied on horizontal wind speed data. This is the more objective methodology to detect wave packets. Horizontal wind speed, meridional and zonal components based on radiosonde launches at Göztepe (Istanbul) between 1993 and 1997 are analyzed. The vertical profiles of meridional and zonal wind components at 850, 700, 500, 300 and 100 hPa pressure heights are transformed by using the Daubechies wavelet and the Morlet wavelet. High wind speed variance observations are identified as gravity wave packets. A strong seasonal cycle and maximum wave variance have been observed in winter. © 2006 by Taylor & Francis Group, LLC.
