On the ionospheric response in the Taiwan region to Typhoon Meranti in September 2016

引用

Geodesy and Geodynamics 2025年第1期16卷 29-41页

作者： Peng Chen Mingzhu Xiong Yibin Yao Hao Chen Fucai Tang Liangcai Qiu Yuchen Zhang College of Geomatics Xi'an University of Science and Technology State key laboratory of Geodesy and Earth's Dynamics Innovation Academy for Precision Measurement Science and Technology Chinese Academy of Science School of Geodesy and Geomatics Wuhan University key laboratory of Geospace environment and Geodesy Ministry of Education Wuhan University

Previous studies have revealed that typhoons can affect the ionosphere. This paper uses GNSS observations provided by GNSS tracking stations of Taiwan region, ERA5 gravity wave dissipation products,and Himawari-8 band 07 brightness temperature observation data to analyze the impact of Typhoon Meranti on Taiwan region's ionosphere from September 13 to 15, 2016. In addition to the daily effects of traveling ionospheric disturbances(TIDs), TIDs of various intensities caused by Meranti-induced gravity waves were observed during this period, which is inseparable from the state of the typhoon and the topographic features during its progress. The ionospheric disturbance caused by the edge of a typhoon is usually larger than that at the typhoon eye. When the typhoon approached Taiwan region with high intensity on September 14, it was observed that the gravity waves caused by the typhoon had a wavelength of about 174-293 km, a period of 13.5-23.5 min, and a propagation speed of 142-302 m/s. When the vortex structure of a typhoon interacts with complex surfaces such as mountains, it is easier to excite more medium-scale gravity waves. The origin that excites gravity waves and causes ionospheric anomalies is different from the location of the typhoon eye and changes over time. The gravity waves caused by the typhoon lasted for three days in the central mountains of Taiwan region. Still, background wind conditions restricted the propagation of gravity waves from the mesosphere to the thermosphere and led to TID predominantly concentrated between 06:00 and 13:00 UT each day.

Integration of CRISPR screening and proteomic analysis of WDR91 manipulation of endosome-to-cytosol transport of African swine fever virus

Dear Editor,African swine fever virus (ASFV) relies heavily on host cellular components for replication, highlighting the complex relationship between the virus and its host(Alcamíet al., 1990). Despite this reliance, the molecular mechanisms governing ASFV infection of host cells remain poorly understood. The low availability of susceptible and permissive cell lines for ASFV replication has hindered research on virus-host interactions, impeding effective antiviral drugs and infection-resistant pig development. Notably, CRISPR screening offers an unbiased and comprehensive method to uncover host factors that are necessary for viral infection,providing a promising avenue for exploring ASFV-host interactions (Puschnik et al., 2017).
