“…Emanuel (2005) showed that, since the mid-1970s, tropical cyclones have become increasingly destructive because of longer storm duration and greater intensity. Sasaki et al (2005) and Yong et al (2008) indicated that summertime extreme wave heights have increased in the western North Pacific during recent years resulting from intense tropical cyclones. Furthermore, extreme hurricane-generated waves in the western North Atlantic have also increased (Komar and Allan 2008;Bromirski and Kossin 2008), and Moore et al (2013) concluded that coastline changes to the U.S. East Coast were attributed to changes in hurricane-generated waves.…”

Future Projections of Extreme Ocean Wave Climates and the Relation to Tropical Cyclones: Ensemble Experiments of MRI-AGCM3.2H*

Future projections of extreme ocean surface wave climates were carried out with single-model ensemble experiments of the atmospheric global climate model MRI-AGCM3.2H. The ensemble experiments of MRI-AGCM3.2H consist of four future sea surface temperature (SST) ensembles and three perturbed physics (PP) ensembles. This study showed that future changes in extreme wave heights strongly depend on the global climate model (GCM) performance to simulate tropical cyclones (TCs), indicating a need to acknowledge that results in a study that employs a low-performance model are not able to account for extreme waves associated with TCs (TC waves). The spatial distribution of future changes in non-TC extreme wave heights on the global scale was similar to that for mean wave heights; namely, wave heights increase over the middleto-high latitudes in the Southern Ocean and central North Pacific and decrease over midlatitudes and the North Atlantic, although the magnitude of future changes for extreme wave heights is greater than for mean wave heights. The variance of future changes mainly depends on differences in physics among PP ensemble experiments rather than differences in SST ensembles. The 10-yr return wave heights of TC waves over the western North Pacific showed either an increase or a decrease of 30% for different regions, maximally. The spatial distribution of future changes in TC waves can be explained by an eastward shift of TC tracks.

“…[6] Spectral wave models are categorized by their primary region of application, i.e., deep water (DW) models such as WAve Modelling (WAM) [WAMDI Group, 1988] and WAVEWATCH-III [Tolman, 1991;Huang et al, 2008], and Shallow Water (SW) models such as Simulating WAves Nearshore (SWAN) [Booij et al, 1999]. Whereas it is generally accepted that DW models are usually more efficient, it would be challenging for DW models to perform as good in shallow waters as SW models because SW models include additional physics representative of the shallow water environment.…”

Gulf of Mexico hurricane wave simulations using SWAN: Bulk formula‐based drag coefficient sensitivity for Hurricane Ike

et al. 2013

[1] The effects of wind input parameterizations on wave estimations under hurricane conditions are examined using the unstructured grid, third-generation wave model, Simulating WAves Nearshore (SWAN). Experiments using Hurricane Ike wind forcing, which impacted the Gulf of Mexico in 2008, illustrate that the default and recommended setting for the wind input parameterization tends to overestimate the maximum significant wave heights in the deep Gulf of Mexico by about 2 m when comparing with observations. The overestimation can be remedied either by adjusting the maximum value of the surface drag coefficient or by substituting a high wind speed formula for the default low to moderate wind speed. Because of added dissipative effects in the shallow coastal areas, the overestimations found in deep water have limited effect on the waves in the near shore shallower waters. Thus, previous wave model results using a low to moderate wind speed bulk formula may still be reliable in waters shallower than about 20-30 m even while overestimating significant wave heights in deeper waters under hurricane conditions.Citation: Huang, Y., R.

This study projected the future ocean wave climate changes based on global climate change scenario using the coupled climate model HadGEM2-AO according to the emission scenarios and using regional wave model. Annual mean significant wave height (SWH) is linked closely to annual mean wind speed during the forthcoming 21st Century. Because annual mean speed decreased in the western North Pacific, annual mean SWH is projected to decrease in the future. The annual mean SWH decreases for the last 30 years of the 21st century relative to the period 1971-2000 are 2~7% for RCP4.5 and 4~11% for RCP8.5, respectively. Also, extreme SWH and wind speed are projected to decrease in the future. In terms of seasonal mean, winter extreme SWH shows similar trend with annual extreme SWH; however, that of summer shows large increasing tendency compared with current climate in the western North Pacific. Therefore, typhoon intensity in the future might be more severe in the future climate.
