摘要
本文利用西太平洋热带海域海-气相互作用与年际气候变化和南沙及邻近海域综合科学考察中的资料,对比分析了船体甲板辐射加热对气温测量的影响是显著的,分析计算了在海-气交换通量中造成的误差是明显的,估计晴好天气中,感热与潜热的误差为感热潜热总和的16％,建议采用在迎风面船舷伸出4m远小百叶箱内的气温为好。
Using observation data of Tropical Western Pacific and Nansha area by the self-manufactured sea surface meteorological observation sampling device QX-1, the dry-and -wet-bulb temperature data of the port and starboard of the ship (at a 4m distance from the shipside, and 10m from the sea surface)and shelter on deck were analysed. The results indicated that temperature difference was obvious between the deck shelter, ship's windward and leeward sides. This is the influence of the ship hull deck radiation heating to air temperature of observation of the sea surface.By using air temperature data of the thermometer screen on deck and the windward side of a ship and other sea hydrometeorological data, sensible heat fluxes latent heat fluxes are calculated. During daytime on a clear day, the error sum of sensible heat fluxes and latent heat fluxes make up 16 per cent of the total heat fluxes value (the sum of the sensible heat and latent heat fluxes are equal to the total heat fluxes value),
