【摘要】：厄爾尼諾不僅危害海洋生物和生態(tài)環(huán)境,還造成全球多個(gè)地區(qū)氣候異常.文中同時(shí)考慮海表溫度、氣壓和降水量3個(gè)環(huán)境要素,采用多個(gè)交互視圖提升對(duì)厄爾尼諾特征的理解和探索分析的深度;使用時(shí)間序列圖和像素矩陣來分析厄爾尼諾的年代際和季節(jié)性規(guī)律,并利用顏色地圖來展示厄爾尼諾相關(guān)的海洋環(huán)境要素的空間分布,同時(shí)構(gòu)建了海表溫度、氣壓和降水量3個(gè)海洋環(huán)境要素的相關(guān)性地圖,以揭示厄爾尼諾表征海域的海洋環(huán)境要素對(duì)全球的海洋環(huán)境要素變化的影響程度;使用平行坐標(biāo)系統(tǒng)和散點(diǎn)圖矩陣展示了海表溫度、海表氣壓、降水量與厄爾尼諾事件間的相互關(guān)系,并利用數(shù)據(jù)重疊率比較了3個(gè)環(huán)境要素對(duì)厄爾尼諾事件的區(qū)分度;最后通過案例分析和用戶使用反饋,展示了該方法的有效性.
[Abstract]:El Nino not only harms marine life and ecological environment, but also causes climate anomalies in many regions of the world. Three environmental factors, sea surface temperature, air pressure and precipitation, are considered at the same time, and several interactive views are used to enhance the understanding of El Nino characteristics and the depth of exploration and analysis. Using time series diagram and pixel matrix to analyze the decadal and seasonal laws of El Nino, and using color map to show the spatial distribution of El Nino related marine environmental elements, and to construct sea surface temperature. The correlation map of three marine environmental elements, pressure and precipitation, to reveal the influence of El Nino on the changes of global marine environmental elements. The relationship between sea surface temperature, sea surface pressure, precipitation and El Nino event is demonstrated by using parallel coordinate system and scatter plot matrix, and the classification of three environmental elements to El Nino event is compared by using data overlap rate. Finally, the effectiveness of the method is demonstrated by case study and user feedback.
