应用气象卫星红外云图,可以对无云(或少云)覆盖的海区,实时了解大范围海水表面温度水平分布.如果结合海上资料,则可以得到现场精度1℃的海水表面温度的水平分布,本文试图对日本“向日葵”气象同步卫星1981年1月12—18日的“麦卡托”红外云图照片,通过日本“Phosdac1200型数字彩色图象分析仪”,将黑自卫片进行假彩色等密度分割使其提高分辨力,结合有关文献资料,分析南海北部冬季海水表面温度实时水平分布的若干特征。这些云图照片是由我所气象实验室利用国产的甚高分辨力卫星云图按收装置接收和提供的,工作频率选在热红外通道(10.5—12.5微米)。
Using meteorological satellite infrared cloud images, it is possible to get a real-time understanding of the surface temperature distribution over a wide range of sea areas without clouds (or less clouds), and if the offshore data are combined, the horizontal distribution of sea surface temperature with on-site accuracy of 1 ℃ can be obtained At the same time, he attempted to photograph the “McCatuo” infrared cloud image of Japan’s “Sunflower” meteorological geostationary satellite from January 12 to January 18, 1981 through Japan’s “Phosdac 1200 digital color image analyzer” Making it improve the resolution, combined with the literature, analysis of the South China Sea in winter sea surface temperature real-time horizontal distribution of several characteristics. These cloud photos were received and provided by our meteorological laboratory using domestically produced very high resolution satellite imagery receivers operating at a frequency of thermal infrared channels (10.5-12.5 microns).
