澳大利亚17个验潮站报告了“气压因子”，即每日平均海平面变化与大气压力变化的比率。示出的气压计因子是明显小于理论值在四个站在澳大利亚东海岸和明显大于理论值在两个站在澳大利亚西海岸。气压因子和相移作为频率的函数，通过频谱分析18个月的记录，提出了四个站。讨论了风应力对海平面的影响，认为风应力的影响很小，不能解释气压因子观测值的异常。观测结果表明，东海岸和西海岸都存在移动的大陆架波。
The ‘barometer factor,’ or ratio of daily mean sea level change to atmospheric pressure change, is reported for 17 Australian tide stations. The barometer factor is shown to be appreciably less than the theoretical value at four stations on the east Australian coast and appreciably greater than the theoretical value at two stations on the west Australian coast. Barometer factors and phase shifts as functions of frequency derived by spectrum analysis of 18-month records are presented for four of the stations. The effect of wind stress on sea level is discussed, and it is concluded that the effect is too small to account for the observed abnormal values of barometer factor. The observations suggest the presence of traveling continental shelf waves on both the east and west coasts.
