海流概率统计特征

非周期性海流作为一种随机变量进行研究,只有具备较长的实测连续资料才可进行分析.本文用概率统计方法分析了黄海和东海六个多昼夜连续海流观测站的资料,得到它们的数字特征.研究结果表明,在A5号站流速模、流向和流速系数均服从一维正态分布;流速的东分量和北分量服从二维正态分布.由于海洋环境的复杂,文中结论还应用与其他海区和台站的资料加以比较验证.

Statiscal Characteristics of Currents

In this paper the statistical method is used to analyse the continuously observed current data at 6 stations in the Yellow Sea and the East China Sea, and digital characteritics are obtained, the study shows that at the A_5 station, the modulus of current, current direction and current speed coefficient all obey one dimensional normal distribution. The X component and Y component of current speed obey two dimensional normal distribution.
