摘要/Abstract

摘要：

在2008—2017年间登陆广东沿海的台风多达25个, 但台风登陆区域周边出现的热辐射异常现象并未引起太多关注。本文利用中国静止气象卫星FY-2C/2E红外遥感亮温资料, 对台风登陆引起的热辐射异常进行分析, 并使用亮温相对功率谱对台风登陆前后热辐射时空分布进行量化。研究发现: 伴随台风的登陆, 大于5倍以上背景值的亮温相对功率谱经历了产生—增加—极大值—减弱—消亡的过程, 其持续时间长于台风过程; 亮温相对功率谱增强的区域与台风登陆路径有一定的相关性, 受限于陆地条件和海洋热量供给; 通过分析台风登陆路径和台风登陆过程中亮温相对功率谱变化趋势可知, 台风登陆前后热辐射持续10~20d, 期间的热异常都与台风过程相关。台风登陆导致热辐射的机制可能与海洋表面降温、水汽聚集等因素有关, 即台风吸收的海洋热量随环流上升过程被海—气相互作用所调制, 导致不同频段和区域出现热辐射差异。

Abstract:

In the period of 2008-2017, there were 25 typhoons that made landfall in the coastal areas of Guangdong, China. However, abnormal thermal radiation around the typhoon landing area has not attracted much attention so far. In this paper, the infrared remote sensing temperature data of Chinese geostationary meteorological satellite FY-2C/2E are used to analyze the thermal radiation anomalies associated with typhoon landfall. The temporal and spatial distributions of thermal radiation before and after typhoon landfall are quantified using bright temperature relative power spectrum (RPS). It is found that with the typhoon landfall, RPS was five times greater than the background value, experiencing a process of generating— increasing—reaching maximum—attenuating—extinction, which lasted longer than the typhoon process itself. There was a correlation between the area with enhanced RPS and typhoon landfall path, limited by terrestrial conditions and ocean heat supply. By analyzing the landfall path and RPS change trend during the typhoon landfall process, we show that the thermal radiation lasted for 10-20 days before and after typhoon landfall, and the thermal anomalies during this period were all related to the typhoon process. The mechanism of thermal radiation anomalies caused by typhoon landfall may be related to the heating leakage and water-vapor accumulation, that is, the ocean heat absorbed by typhoon is modulated by the air-sea interaction as the air rises, resulting in thermal radiation variation in different frequency bands and regions.
