孤立波在物理和数学科学中引起了极大的兴趣。这些非线性波似乎常常在内陆湖泊和沿海水域（2 - 4）、公海的温跃层(5)和低层大气（6,7）中传播扰动的渐近描述中起主要作用。我们在这里提出了在澳大利亚干旱内陆的Tennant Creek对复杂对流层孤立波扰动的新声学观测结果（图1），对澳大利亚北部出现的一种新型可见波现象的描述和解释，这种现象表现为薄传播的云云线，并讨论了在卡彭塔利亚湾的伯克敦观测到的一种新型低空传播的孤立波卷云，这种云起源于南部。当这些观测结果与坦南特溪的观测结果相关联时，表明产生孤波的干扰以内部孔的形式8,9传播很远的距离。
Solitary waves are of intense interest in the physical and mathematical sciences1. These nonlinear waves often seem to have a primary role in the asymptotic description of propagating disturbances in inland lakes and coastal waters2–4, in the thermocline of the open sea5 and in the lower atmosphere6,7. We present here new acoustic sounder observations of complex tropospheric solitary-wave disturbances at Tennant Creek in the arid interior of Australia (Fig. 1), a description and interpretation of a new type of visible wave phenomena over northern Australia which appear as thin propagating cumulus cloud lines, and a discussion of observations at Burketown on the Gulf of Carpentaria of a new class of low-altitude propagating solitary-wave roll clouds which originate to the south. These observations, when correlated with observations at Tennant Creek, indicate that solitary-wave-generating disturbances in the form of internal bores8,9 propagate over large distances.
