RELATION OF GLOBAL AND REGIONAL ATMOSPHERIC-WAVE CLIMATE SYSTEMS

Climate change and variability are becoming important for coastal engineering research. Although the impact of climate change impact on the wave climate became clear after IPCC 5th (2012) and 6th (2021) Assessment Reports, the characteristics of natural variability, ENSO, North Atlantic Oscillation (NAO), and others in the wave climate system. The evaluation and the impact of historical climate variability on the wave climate system are important global and regional coastal feature understandings (e.g., Casas- Prat, 2023). This study develops a highly accurate statistical analysis for global and regional wave climate by introducing the principal component information of the atmospheric field from a wide-area atmospheric field with regional wind and pressure fields. We discuss the role of global and regional atmospheric weather systems on the regional monthly wave climate.
