河北省沿岸表层温盐特征分析

Characteristics of sea surface temperature and salinity at tidal gauge stations along Hebei coast

本文基于河北省沿岸4个海洋站的观测数据,综合统计分析该海域的表层海水温度和盐度,发现其具有地域性和季节性特征。表层水温存在年际变化和上升趋势,与气温显著相关,反映出其对海气相互作用的响应。表层盐度主要受黄河径流量的影响,秦皇岛站的表层盐度与黄河径流量存在明显的负相关性,表层盐度对黄河径流量的响应存在一年的滞后。

Based on the observation data of four marine stations along the coast of Hebei province,this paper comprehensively analyzes the sea surface temperature and salinity,reveals the regional and seasonal characteristics of sea surface temperature and salinity.sea surface temperature has an interannual variation and rising trend,which is obviously related to the temperature,reflecting its response to air-sea interaction.Sea surface salinity is mainly affected by the runoff of the Yellow River.There is an obvious negative and one-year lag correlation between the sea surface salinity of Qinhuangdao station and the Yellow River runoff.
