Magnetohydrodynamic (MHD) waves are believed to be a global indicator of magnetotail processes. Even if the wave source is localized, the wave propagates to various parts of the magnetosphere and thus dynamical phenomena in the magnetotail would be monitored. Since the plasma density and magnetic field are spatially variable, the phase fronts of the MHD waves are highly distorted due to inhomogeneity. Thus, it is important to understand the global spatial structure of MHD wave speed. To calculate the wave speed in the magnetotail, we use the plasma and magnetic field data acquired from the Geotail spacecraft in two years (1996-1997). From these statistical values, we present the map of Alfven and sound speeds in the near-Earth magnetotail (ěrt XGSM ěrt = 10 ˜ 30 RE, ěrt YGSM ěrt < 10 RE). We also investigate the effects of seasonal variations and geomagnetic activities on these speed profiles.
