| 520 | 3 |a"A decade of extremes of astronomical seeing is studied in connection with atmospheric conditions. An attempt is made to relate seeing to turbulence parameters, especially those parameters favouring turbulence at tropopause levels. The gravity wave-vertical shear mechanism is found to be significantly related to poor seeing conditions, suggesting that clear air turbulence is strongly involved in poor astronomical seeing"--Abstract. |
