摘要
热带气旋(TC)快速增强(RI)对我国影响大且预报难度较大,在常规观测资料稀少的海洋上,卫星探测技术的发展,提供了更多的RI TC内部结构变化的有效信息,能够帮助人们进一步认识TC强度的变化规律。文中总结了静止轨道及极地轨道卫星上搭载的可见/红外扫描仪、微波成像仪、降水测量雷达、风场测量仪器、闪电成像仪和云雷达资料在TC RI中的应用以及存在的问题,指出发展小卫星星座及静止轨道微波探测,加强RI TC内部的降水、云微物理和风场等重要信息的时间演变分析,并结合数值模拟进一步研究TC RI的物理机制将是未来的发展方向。
Rapidly intensifying(RI)tropical cyclones(TC)are difficult to be predicted and often cause severe disasters.On the ocean with few regular observations,the development of satellite detection technology provides more effective information of TC internal structure variations,and can help to further understanding the variation rule of TC intensity.The application of visible/infrared scanner,microwave imager,precipitation measurement radar,wind field measurement instrument,lightning imager and cloud radar data on the geostationary and polar orbit satellites in TC RI as well as the existing problems were discussed.The development of small satellite constellation and microwave detection aboard geostationary satellites that strengthen the evolution observation of important information such as precipitation,cloud microphysics and wind field in RI TC were pointed out,and further study on the physical mechanism of RI in combination with numerical simulation will be the direction for future research.
