【摘要】：丹麥海峽海洋鋒可為局地氣候變化、海峽魚(yú)類分布以及海峽中尺度渦等方面研究提供參考,在軍事領(lǐng)域也具有較高應(yīng)用價(jià)值。然而目前國(guó)內(nèi)外缺乏對(duì)于丹麥海峽鋒的系統(tǒng)研究。本文利用WOA13數(shù)據(jù),對(duì)丹麥海峽鋒位置、強(qiáng)度空間分布以及相應(yīng)的季節(jié)變化進(jìn)行了分析。結(jié)果顯示,鋒軸線位置在34°W以西150m以淺相對(duì)穩(wěn)定,34°W以東鋒軸線隨深度和季節(jié)均有擺動(dòng)。鋒強(qiáng)度在水平和垂直方向分布不均勻,水平方向上鋒軸線最大值與最小值差值一般在3倍以上。垂直方向鹽度鋒主要集中在100m以淺,且強(qiáng)度隨深度不斷減小;溫度鋒強(qiáng)度最大值在表層以下且在300m以深隨深度增加鋒強(qiáng)度減小,但有一些區(qū)域如27°W和28°W附近,受到海底地形的影響溫度鋒強(qiáng)度隨著深度的變化有大幅度增加的特點(diǎn)。
[Abstract]:The sea front in the Danish Strait can be used as a reference for the study of local climate change, fish distribution and mesoscale vorticity in the Strait, and also has a high application value in the military field. However, there is a lack of systematic research on the Danish Strait front at home and abroad. Based on WOA13 data, the position, intensity spatial distribution and seasonal variation of the front in the Danish Strait are analyzed. The results show that the position of the front axis is about 150 m west of 34 擄W, and the axis of the front east of 34 擄W is relatively stable with the depth and season. The distribution of the front strength is not uniform in horizontal and vertical directions, and the difference between the maximum and minimum of the axis of the front in horizontal direction is generally more than 3 times. The vertical salinity front is mainly shallow at 100 m and the intensity decreases with the depth, and the maximum intensity of the temperature front decreases below the surface layer and increases with the depth at 300 m, but there are some regions such as 27 擄W and 28 擄W. The intensity of temperature front increases greatly with the change of depth due to the influence of submarine topography.
