Implementation of spectral partition in wave models(波浪数学模型中谱分割功能的应用)

Zhejiang Daxue xuebao. Lixue ban, 2012
海洋风浪的数值模拟常以全谱有效波高作为模拟结果，并在验证时将它与实测风浪记录相对比.实际上，全谱中既包含了当地风浪部分，也包括了外海传入的涌浪部分，其有效波高在物理意义上并不等价于风浪波高.采用海浪模型WAVEWATCH-III和MIKE21-SW进行西北太平洋海域的风浪后报，并应用模型的谱分割功能，可对完整的波谱进行分割，分离出风浪和涌浪部分.数值计算结果对比证实：利用该功能得到的分离波高不仅能提高风浪模拟的精度，也使波能状态信息更加完善.另外，对比发现WAVEWATCH-III相对于MIKE21 ...

Extreme wave event in Ilha Grande Bay: a case study

Boletim do Observatório Ambiental Alberto Ribeiro Lamego, 2012
This study aims to understand the propagation of wind-generated waves, through numerical modeling, in Ilha Grande Bay, using two different scenarios: a typical and a storm wave situation.

Unraveling the Source Locations of Short‐Period Secondary Microseisms

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Primary and secondary microseisms are generated by ocean wave interactions, with the latter occasionally split into short‐ and long‐period bands in some regions. The short‐period secondary microseism (SPSM) sources have traditionally been associated with nearby coastal segments, suggesting a more uniform distribution across shorelines.

Deployment Strategy Shapes the Polar Climate Response to Marine Cloud Brightening

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Marine cloud brightening (MCB) is a proposed solar climate intervention strategy that increases marine cloud reflectivity to cool Earth's surface. While previous studies have largely examined its global temperature and precipitation effects, little is known about how MCB deployment strategies influence polar climate and sea ice.

Revealing Coastal Storm‐Wave Transformations From SWOT HR Observation: The English Channel Case Study

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Swell propagation and transformation across variable bathymetry and coastal obstacles fundamentally control nearshore wave energy redistribution, sediment transport, and shoreline evolution. Conventional satellite altimetry cannot adequately resolve these dynamics, particularly refraction and diffraction as swell transition into shallow waters.

The influence of ex‐tropical cyclones on marine terrace retreat

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Ex‐tropical cyclones can damage the integrity of marine terrace structures and contribute to erosion, but they are sometimes too infrequent to explain the longer term erosion rates of coastlines. Abstract High magnitude events, like Ex‐Tropical Cyclones, are likely to change in their trajectory, magnitude, and frequency under future climate change ...

Evaluating the gravity wave energy potential off the Brazilian coast

Brazilian Journal of Oceanography
The wave energy potential on the Brazilian coast is estimated using in-situ buoy data and model data. The results present a greater potential on the southern-southeastern coast than on the northeastern coast, but the variance is also larger.

Assessing the Performance of the Dissipation Parameterizations in WAVEWATCH III Using Collocated Altimetry Data

Journal of Physical Oceanography, 2009
Abstract Wave-breaking dissipation is one of the least understood processes implemented in contemporary wave models. Significant effort has been put in its parameterization, but it has not proven to be totally satisfactory, either theoretically or practically.

EVALUASI MODEL WAVEWATCH-III MENGGUNAKAN DATA SATELIT ALTIMETRI DAN OBSERVASI [PDF]

Jurnal Meteorologi dan Geofisika, 2018
Model gelombang menjadi komponen utama dalam memberikan informasi prediksi gelombang dewasa ini. Hal ini terjadi akibat terbatasnya pengamatan in-situ yang dilakukan untuk mengamati lautan secara umum. Model prakiraan gelombang telah mengalami evolusi, mulai dari generasi pertama dan berkembang sampai model generasi tiga.
