| 摘 要： | 波浪破碎诱导生成的海盐粒子是海洋向大气输运无机盐的主要机制,海气界面的无机盐通量对于全球气候变化有重要影响。本文开展了实验室实验模拟海盐粒子生成实验,定量考察了温度和盐度对海盐粒子中离子质量分布的影响,揭示了初生海盐粒子中各离子的富集和亏损现象与温度和盐度的关系。基于实验室观测分析结果和推测假定,提出了1个既包含海面风速、又反映海表温度和海表盐度影响的海-气无机盐通量参数化方案。将此参数化方案应用于估计海盐粒子向大气输运的各种无机盐离子质量通量,并与传统方法估算结果进行了比对分析。

| Abstract: | The sea salt particle(SSP) induced by wave breaking is the main mechanism transferring the inorganic salt from ocean to atmosphere.It is believed that the inorganic salt flux at the air-sea interface plays an important role in global climate change.In the present paper,the laboratory experiments for simulating the SSP production process are carried out,in order to investigate quantitatively the effect of temperature and salinity of sea water on the mass fractions of ions in SSP.It is indicated that the enrichment or fractionation of the ions in the nascent SSP is much closely related to temperature and salinity of sea water.On the basis of the experimental results and some assumptions,a parameterization of air-sea inorganic salt flux has been proposed,in which both wind speed,and sea surface temperature and sea surface salinity are included.The proposed parameterization is applied to estimate the air-sea mass flux of various ions transferred by SSP,in comparison with the traditional estimation. |
