SOLVING THE SEA SURFACE TEMPERATURE FROM THE INFRARED RADIATION HEAT BALANCE EQUATION

针对海面红外仿真中需要输入实时海面温度的要求 ,本文从海面的热平衡方程出发 ,将平衡方程中的各项 ,如太阳辐射、天空辐射、海面自发射、海面与大气的热交换等用温度的函数表示 ,然后从平衡方程中解出海面温度 .最后模拟了海面温度随太阳辐照、天空辐照、风速、相对湿度的变化 .

In order to obtain real-time input of sea surface temperature in infrared simulation of sea surface, the heat balance equation of infrared radiation at the sea surface are given, and every term in the equation, such as the solar radiation, the radiation from the sky, the self emission radiation of sea surface, heat exchange between the sea surface and the atmosphere are expressed as a function of temperature, then the sea surface temperature is calculated by solving the equation. Finally the changes of sea surface temperature along with the variation of solar radiation, radiation from the sky, wind speed, and relative humidity are simulated, which shows that the model is correct and reliable.
