    摘要:

    基于环境减灾卫星的热红外波段数据,采用普适性单通道温度反演算法反演了田湾核电厂附近海域海面温度,反演结果与MODIS海面温度产品具有一致性,然后依据反演所得海面温度分布图,对不同季节和不同潮汐条件下温排水的分布特征进行了分析,结果表明, 夏季温升超过3℃的区域明显小于冬季,夏季温排水沿海岸单向扩散,冬季的温升区域呈扇形分布;低潮时温排水扩散范围明显增大,温升超过3℃的区域面积超过高潮时的4倍.

    Abstract:

    Based on the thermal infrared data obtained from environmental mitigation satellite, the sea surface temperature (SST) was retrieved using generalized single-channel method to get the quantitative information about the diffusion of the thermal discharge around the Tianwan Nuclear Power Plant. It indicated that the retrieved SST was consistent with the MODIS SST product. Based on the retrieved SST distribution map, the thermal field variations in different seasons and tides were analyzed. The area where the SST has increased more than 3℃ in winter was much larger than that in summer. During the winter months, the thermal discharge extended to a sector area around the power station, while in summer it was limited to a longer and narrower area in one side of the bay. The thermal fields at low tide were rather larger than that at high tide, with the area where the SST has increased more than 3℃ four times larger than that at high tide.
