Distinct atmospheric disturbances with zonal wave number 1 were found in the summer southern polar region of Mars using the Mars Global Surveyor (MGS) Thermal Emission Spectrometer (TES) retrieved temperatures provided by NASA. Our investigations show that the polar disturbances exist during summer (Ls = 250¿--270¿) in three consecutive Martian years. These disturbances have phase structures tilted westward with height, and connected with near-surface temperature anomalies whose maxima and minima are largely fixed to those of the surface temperature associated with the axially asymmetric polar cap. Such a wave structure is consistent with stationary planetary waves that are forced by axially asymmetric surface temperature anomaly and propagate upward in weak eastward winds flowing over the polar cap.
