Abstract. The tides in the Taiwan Strait (TS) feature large semidiurnal lunar (M2) amplitudes. An extended Taylor method is employed in this study to provide an analytical model for the M2 tide in the TS. The strait is idealized as a rectangular basin with a uniform depth, and the Coriolis force and bottom friction are retained in the governing equations. The observed tides at the northern and southern openings are used as open boundary conditions. The obtained analytical solution, which consists of a stronger southward propagating Kelvin wave, a weaker northward propagating Kelvin wave, and two families of Poincaré modes trapped at the northern and southern openings, agrees well with the observations in the strait. The superposition of two Kelvin waves basically represents the observed tidal pattern, including an anti-nodal band in the central strait, and the cross-strait asymmetry (greater amplitudes in the west and smaller in the east) of the anti-nodal band. Inclusion of Poincaré modes further improves the model result in that the cross-strait asymmetry can be better reproduced. To explore the formation mechanism of the northward propagating wave in the TS, three experiments are carried out, including the deep basin south of the strait. The results show that the southward incident wave is reflected to form a northward wave by the abruptly deepened topography south of the strait, but the reflected wave is slightly weaker than the northward wave obtained from the above analytical solution, in which the southern open boundary condition is specified with observations. Inclusion of the forcing at the Luzon Strait strengthens the northward Kelvin wave in the TS, and the forcing is thus of some (but lesser) importance to the M2 tide in the TS.

Mobility across the Taiwan Strait has intensified since the border was opened in 1987. The cross-border social, cultural and economic exchanges, however, have remained closely embedded in the nationalistic logic specific to cross-Strait relations. Employing a state-centered approach and building on a comparative analysis of the interaction between Beijing and two groups of cross-Strait migrants (mainland spouses in Taiwan, and Taiwanese investors in China), this paper examines the various ways in which a state may still exert influence over migrant communities in a context of increased mobility and exchanges. This paper argues that the nation-state may still shape migrants’ experiences, particularly when sending and receiving governments have unresolved disputes. Under these conditions, state actors may use migrant communities to achieve their nationalistic goals.

The Relationship

This special section includes four papers to examine the ups and downs of the relationship between Taiwan and China. While both sides of the Taiwan Strait have different political systems, these studies show that domestic politics play a central role in explaining the oscillation of the cross-Strait relationship. The findings provide evidence of the interaction between domestic and external factors. Leaders in Beijing and Taipei therefore need to take heed of the internal forces of both sides of the Taiwan Strait in addressing their contentious relationship.

The purpose of this state-of-the-field article is to take stock of the use of international relations theory in the study of cross-Strait relations since 2000. To what degree have studies of cross-Strait relations made use of international relations theory since 2000, and to what degree has international relations theory provided useful insights for understanding Beijing–Taipei relations? I focus my attention on five topics in particular: the prospects for armed conflict in the Taiwan Strait; alliance/alignment politics and the u.s.–China–Taiwan triangular relationship; interactions between domestic politics (in Taipei and Beijing) and the cross-Strait dyadic relationship; cross-Strait economic integration in the shadow of political conflict; and the role of psychology, emotion, and identity in shaping cross-Strait interactions. For each topic, I survey recent studies that apply rigorous international relations theory to the cross-Strait relationship, and where appropriate I make suggestions for further development.

AbstractThis study shows that mesoscale eddies can alter the Taiwan Strait Current. The 20-yr data-assimilated Japan Coastal Ocean Predictability Experiment 2 (JCOPE2) reanalysis data are analyzed, and the results are confirmed with idealized experiments. The leading wind-forced seasonal cycle is excluded to focus on the effect of the eddy. The warm eddy southwest of Taiwan is shown to generate a northward flow, whereas the cold eddy produces a southward current. The effect of the eddy penetrates onto the shelf through the joint effect of baroclinicity and relief (JEBAR). The cross-isobath fluxes lead to shelfward convergence and divergence, setting up the modulation of the sea level slope. The resulting along-strait current anomaly eventually affects a wide area of the Taiwan Strait. The stronger eddy leads to larger modification of the cross-shelf flows and sea level slope, producing a greater transport anomaly. The composite Sea-Viewing Wide Field-of-View Sensor chlorophyll-a (Chl-a) serves as an indicator to show the change in Chl-a concentration in the strait in response to the eddy-induced current. During the warm eddy period, the current carries the southern water of lower concentration northward, reducing Chl-a concentration in the strait. In contrast, Chl-a is enhanced because the cold eddy–induced southward current carries the northern water of higher concentration southward into the strait.

Economic Globalisation

<p>The further development of economic globalisation causes the status and effect of economic factors to continuously increase in international relations. This new characteristic is increasingly apparent in cross-strait relations as the course of the reform and opening-up in mainland China, as well as the development of cross-strait economy and trade. Particularly since the mainland and Taiwan signed Economic Cooperation Framework Agreement (ECFA) in 2010, economic development has become one of the most important issues between the two sides. Since the détente between the mainland and Taiwan in the 1980s, cross-strait economics and trade have displayed two primary characteristics. First, the volume of trade, the amount of investment, and especially the economic interdependency between the two sides are all constantly increasing. Second, although under the influence of fluctuating political relations, the cross-strait economic relationship is still maintaining a stable development tendency. Due to the impact of economic globalisation, both the mainland and Taiwan are re-examining their own economic interests and have realized that economic relations form the cornerstone of their relationship. The expanding common interest which is generated from the deepening cross-strait economic exchanges between the mainland and Taiwan is becoming the key factor in both governments’ political considerations. Cross-strait economic and trade development is thus becoming an interests mechanism which maintains the framework of peace and stability across the Taiwan Strait. This thesis argues that cross-strait economic interdependence and cross-strait relations are inherently and interactively related. From the viewpoint of Neoliberalist Theory and Interdependent Theory, and on the basis of the development course of cross-strait economy and trade, this article analyzes the interactive effect between the cross-strait economy and cross-strait relations, especially the political relations from many factors such as the signing of ECFA, the impact of Taiwanese businessmen’s investment in the mainland, and the mainland's Taiwan policy. This thesis concludes that on the one hand, the increase in cross-strait economic interdependence will promote peace and stability across the Taiwan Strait. On the other hand, stable cross-strait relations will also provide a policy guarantee and a peaceful scope for the future development of the relationship between mainland China and Taiwan.</p>
