【摘要】：文章為大亞灣潮汐動(dòng)力學(xué)系列研究論文的第二部分,主要關(guān)注大亞灣雙峰水位現(xiàn)象和漲潮流速雙峰現(xiàn)象的產(chǎn)生機(jī)制�；谇叭搜芯砍晒蛿�(shù)學(xué)解析方法,得出在大亞灣海域水位的雙峰現(xiàn)象主要是由以M_2為代表的半日分潮與四分之一日分潮(如M_4分潮)和六分之一日分潮(如M-_6分潮)共同作用造成的。并對(duì)產(chǎn)生雙峰水位和漲潮流速雙峰的條件進(jìn)行了數(shù)學(xué)解析,利用數(shù)值模擬結(jié)果發(fā)現(xiàn),M_2/M_4分潮組合在大亞灣并不能產(chǎn)生雙峰水位現(xiàn)象,而M_2/M_6分潮組合只能在大亞灣東北的范和港產(chǎn)生雙峰水位現(xiàn)象。相對(duì)而言,M_2、M_4和M_6 3個(gè)分潮疊加的組合在雙峰水位的產(chǎn)生范圍和雙峰間落差上都要大于上述2個(gè)分潮的組合。在大亞灣灣內(nèi)區(qū)域,漲潮流速雙峰可以由M_2/M_4分潮組合,M_2/M_6分潮組合和M_2/M_4/M_6分潮組合產(chǎn)生,M_2/M_4/M_6分潮產(chǎn)生的漲潮流速雙峰強(qiáng)度要比另外兩組分潮組合大。
[Abstract]:This paper is the second part of a series of studies on tidal dynamics in Daya Bay, focusing on the mechanism of the bimodal water level phenomenon and the bimodal tidal velocity phenomenon in Daya Bay. Based on previous research results and mathematical analytical methods, It is concluded that the bimodal phenomenon of water level in Daya Bay is mainly caused by the action of the half-day tide represented by M _ (2), the one-day tide (such as M _ 4) and the one-sixth tide (such as M-6). The condition of producing double peak water level and rising tide velocity double peak is analyzed. By using the numerical simulation results, it is found that the two-peak water level phenomenon can not be produced in Daya Bay by the combination of M _ (2) / M _ (4) min tide. The M-2 / M6 tidal component can only produce bimodal water level phenomenon in Fan and Gang northeast of Daya Bay. Comparatively speaking, the combination of M _ 2M _ S _ 4 and M _ 6 is larger than the combination of the above mentioned two tidal components in the generation range and the drop difference between the two peaks. In the area of Daya Bay, the double peak of high tide velocity can be generated by MSP 2 / M 4 tide assemblage, M2 / M 4 minute tide combination, M2 / M / M 6 tide combination, and M 2 / M 4 / M 6 tide combination, and by M 2 / M 4 / M 6 tide combination, the peak strength of the two peaks is higher than that of the other two component tidal combinations, which are generated by the M 2 / M 4 / M 6 tide.
