ABSTRACT

This work revisits and extends an analysis of the Australian wave observing network. The method is based on calculating correlations between modelled wave variables at observation sites and the Australian coastal domain and identifying areas of low correlation. This gives an indication of the areas where variability of the wave fields is poorly captured by existing observation locations, i.e. the network gaps. It is found that the gaps in the network that had been identified in previous work are to a large part reduced by the recent deployment of new infrastructure, but not eliminated. It is also found that the network does less well at observing the synoptic scale wave field than it does at observing the monthly wave climate. Lagged correlations are also considered but found to have only a modest impact on the ability of the network to observe the wave field variability.

摘要

这项工作重新审视并扩展了对澳大利亚波浪观测网络的分析。该方法基于计算观测点模拟波浪变量与澳大利亚沿海地区之间的相关性，并确定相关性低的区域。这给出了现有观测位置无法很好地捕获波场变化的区域的指示，即网络间隙。结果发现，最近部署的新基础设施在很大程度上减少了之前工作中发现的网络差距，但并未消除。还发现该网络在观测天气尺度波场方面不如在观测月波气候方面做得好。
