Abstract We use the WAVEWATCH-III model to quantify the effect of oceanic current on typhoon-wave modeling in the East-China-Sea (ECS). Typhoons Jelawat and Saomai in the autumn of 2000 are hindcasted. The oceanic currents in the ECS are mainly constituted of Kuroshio and typhoon-generated currents. The results show distinguishable differences in wave height and wave period under the typhoon conditions. The oceanic current causes the maximum differences, of up to a 0.5 m significant wave height and a 1 s mean wave period. Comparisons between typhoons Jelawat and Saomai show the dependence of the current effect on the typhoon characteristics.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
