Abstract

Results of the study of water exchange between the Azov and Black seas based on the data of contact measurements in 2019 are presented. Estimates of the scale of the Sea of Azov plume were obtained under conditions of a strong northeasterly wind (9–10 m/s). The results of field measurements confirmed the determining role of wind in water exchange through the Kerch Strait, which made it possible to form statistics on the flow of the Sea of Azov waters into the Black Sea based on wind reanalysis data over the past twenty years. A new method for calculating the flow of the Sea of Azov water through the Kerch Strait based on the comparison of satellite and field data is proposed and applied. The calculation of the Sea of Azov water transport is generally based on the assessment of the spatial characteristics of the Sea of Azov plume in the Black Sea and, in particular, on the determination of the dependence of its area on wind parameters. The average annual transport of the Sea of Azov water estimated using the new method practically coincides with the average value of all estimates of water exchange through the Kerch Strait, obtained using other calculation methods. We also considered the reverse case of the inflow of the Black Sea waters into the Sea of Azov after the end of the period of intense flow of the Sea of Azov waters into the Black Sea.

2019年基于历史数据和接触测量的刻赤海峡水交换研究

摘要

介绍了基于 2019 年接触测量数据的亚速海和黑海之间的水交换研究结果。在强东北风 (9-10 m/s) 的条件下获得了对亚速海羽流规模的估计。现场测量结果证实了风在刻赤海峡水交换中的决定作用，这使得基于过去二十年风再分析数据形成亚速海流入黑海的流量统计成为可能。提出并应用了一种基于卫星和现场数据比较计算亚速海流经刻赤海峡的水流量的新方法。亚速海水运的计算通常基于对黑海亚速海羽流空间特征的评估，特别是确定其面积对风参数的依赖性。使用新方法估计的亚速海年平均水运量实际上与使用其他计算方法获得的通过刻赤海峡的所有水交换估计值的平均值相吻合。我们还考虑了在亚速海水域强烈流入黑海的时期结束后黑海水域流入亚速海的相反情况。使用新方法估计的亚速海年平均水运量实际上与使用其他计算方法获得的通过刻赤海峡的所有水交换估计值的平均值相吻合。我们还考虑了在亚速海水域强烈流入黑海的时期结束后黑海水域流入亚速海的相反情况。使用新方法估计的亚速海年平均水运量实际上与使用其他计算方法获得的通过刻赤海峡的所有水交换估计值的平均值相吻合。我们还考虑了在亚速海水域强烈流入黑海的时期结束后黑海水域流入亚速海的相反情况。
