建立了一个太湖水温数值模型,模拟太湖平均水温的日变化过程。应用本模式和由太湖气象水文数据自动采集系统测得的资料(1990年9月26—27日)分析了气温、湿度和风速对水温的影响。由计算和数值试验结果看出,本模式较好地模拟出了选定的两天中水温变化过程;随着空气温度的增加,水温线性增加;在空气相对湿度较大或风速较小时,它们的变化对水温有较大的影响。
A numerical model of Taihu Lake water temperature was established to simulate the diurnal variation of average Taihu Lake water temperature. Based on the data obtained from the automatic acquisition system of Taihu Lake meteorological and hydrological data (September 26-27, 1990), the effects of temperature, humidity and wind speed on water temperature were analyzed. According to the results of numerical and numerical experiments, this model better simulates the change of water temperature during the selected two days. As the air temperature increases, the water temperature increases linearly. When the relative humidity of air is relatively high or the wind speed is small, The changes have a greater impact on water temperature.
