摘要
将南海西沙海区2000年5~6月海面辐射通量(包括太阳短波辐射、海面反射辐射、大气逆辐射和海面长波辐射)与云量、海温、气温、水汽压等气象要素进行了对比分析,发现它们之间存在一定的相关关系,利用这些关系建立了适合于计算南海西沙海区的太阳短波辐射、大气逆辐射、海面长波辐射和海面反照度的经验公式.分析结果表明,采用本文经验公式计算的各辐射通量值与实测资料的误差较一般常用经验公式的计算误差均有不同程度的减小,计算结果与实测结果在变化趋势上也具有较好的一致性.
Observational radiation flux data(including solar radiation, reflected radiation from sea surface, atmospheric radiation and long-waved radiation from the sea ) at sea surface of XiSha sea area of the South China Sea from May to June 2000 and some regular data such as the quantity of clouds, surface sea temperature, atmospheric temperature, water vapor and so on are studied and analyzed in this article. We find out that there is some relationships between the radiation flux data and regular data. Making use of these relations, we establish the empirical formulae which are appropriate to calculate solar radiation, atmospheric radiation, long-waved radiation from the sea and albedo from sea surface in XiSha sea area of the South China Sea. The results show that error margins calculated by the formulae mentioned above decrease compared with the ones calculated by common formulae. There is a relatively better consistency between the observation and the results calculated by our formulae.
