摘要

在耦合的区域气候化学模式RegCCMS中增加了海盐的起盐机制, 并引入海盐的光学参数, 使之能够模拟海盐气溶胶浓度的时空演变特征和直接气候效应, 研究了2006年四季(以1, 4, 7和10月为代表)东亚海盐气溶胶的空间分布、直接辐射强迫及其直接气候效应。结果表明, 东亚海域海盐气溶胶年平均浓度达14.69 μg·m-3, 冬季为26.27 μg·m-3, 夏季为7.59 μg·m-3; 海盐气溶胶高值中心呈明显的季节变化, 冬季高值中心主要在南海, 夏季在黄海。晴空条件下该区域年平均海盐气溶胶的直接辐射强迫在大气顶达-2.35 W·m-2, 在有云条件下达-1.17 W·m-2。海盐气溶胶直接气候效应导致海岛及沿海陆地降温, 其中在7月和1月台湾降温分别为-0.1094 K和-0.0083 K, 沿海陆地则分别为-0.1330 K和-0.0142 K。

Abstract

Sea salt aerosol (SSA) is one of the most important aerosol components in atmosphere, which plays very important role in atmospheric environment and climate change. The regional climate and chemistry modeling system RegCCMS was further developed and applied to investigate the spatial and temporal characteristics of sea salt aerosol as well as its direct effect. Here we present numerical simulations on sea salt aerosol concentrations and then its direct climate responses in January, April, July and October 2006, representing for four seasons. The annual mean concentration of SSA over ocean areas of East Asia reaches 14.69 μg·m-3. The maximum concentration of 26.27 μg·m-3 occurs in winter, while the minimum concentration of 7.59 μg·m-3 occurs in summer. The results indicate that the spatial and temporal distribution of SSA shows obvious seasonal variation. The high value center of SSA concentration appears in the South China Sea in winter and in the Yellow Sea in summer. The annual direct radiative forcing at the top of atmosphere of SSA in this area is estimated to be -2.35 W·m-2 and -1.17 W·m-2 for clear sky and all sky, respectively. The direct climate effects of SSA lead to cooling over the coastal land and islands. For Taiwan, the cooling is -1.0940 K, -0.0083 K in July and January, respectively. For the coastal land, the coolings in July and January are -0.1330 K and -0.0142 K, respectively.
