摘要:
本文介绍了利用船测温度外部定标解译卫星红外云图海面温度场及其简化应用的方法。其计算处理方程为: Te=T1+αT12(De-D1)-βT12ln(τ1τ2)简化应用的方程为: Te=T1[1+αT1(De-D1)] 诺阿卫星红外云图的水温解译图能够显示表面水温和黄、东海区冷暖系锋面及其流隔的时空变化。 在冬春季节,计算温度与船测表面温度比较。其结果是: 1.总体均绝差1.0℃左右; 2.相关系数0.9以上。 如果能够获得一系列晴空的云图和它的解译图,则对渔海况预报和渔场海洋学的研究及渔业生产具有很大的价值。
The present paper describes a method of interpreting the sea surface temperature field of infrared cloud picture using ship-measured temperature and its simple application. The complete equation for caculation can be expressed as follows, Te=T1+αT12(De-D1)-βT12ln(τ1τ2) and the simplified equation can be reduced to Te=T1[1+αT1(De-D1)] The interpretation charts of the NOAA satellite infared cloud picture show the distribution of SST and cold-warm fronts of water system of the Huanghai Sea and the East China Sea as well as the variation of the current with time and space.Comparing the caculated temperature with the ship-measured SST in winter and spring, it was obtained that the overall mean absolute error was about 1.0℃ and the correlation coefficients were 90 percent or more.A series of cloud-free images and their interpretation charts, if they can be obtained, will be great value for the forecast of fishing-sea conditions, the research on fishery oceangraphy and the fishing operation.
