## 4 Results and Discussion
### Comprehensive Analysis of Typhoon-Induced Oceanic and Societal Impacts  
Based on the news retrieval from the \"China National Knowledge Infrastructure (CNKI)-China Important Newspapers Full-text Database\", the distribution of topics in

Figure 5: Training and validation loss across folds for cross-validation analysis. typhoon news reports from 2011 to 2020 exhibits a marked imbalance, reflecting the extensive impact of typhoons on various domains, including society, economy, and politics. As previously discussed, typhoons, as extreme meteorological events, not only exert profound effects on the marine environment but also significantly influence multiple aspects of society, a fact that is clearly reflected in the media coverage. Figure 6 illustrates that political topics dominate the majority of typhoon-related news reports. These reports predominantly focus on government responses and decisions in the wake of typhoon disasters, including the convening of important meetings, policy implementation, public statements by leaders, as well as government-led rescue and post-disaster reconstruction efforts. Such coverage highlights the central role of the government in disaster management, underscoring the dominance of political power in handling typhoon-related crises. Although economic topics rank second in terms of coverage, they remain a critical component of the reporting. Economic reports often center on the direct financial losses caused by typhoons and the subsequent progress of reconstruction efforts. This is closely related to the significant impact of typhoons on economic systems, particularly within industries such as insurance, agriculture, and telecommunications. The reports also emphasize the social responsibility and actions of these sectors during disaster recovery, echoing the earlier discussion of the far-reaching economic impacts of typhoons. In contrast, ecological and scientific topics receive relatively less coverage, yet they are crucial for understanding the ecological and scientific implications of typhoons. Ecological reports typically address the impacts of typhoons on meteorological conditions, the implementation of ecological flood control measures, and the application of meteorological monitoring technologies. This aligns with the earlier discussion on the effects of typhoons on ocean heat content, salinity, and other related aspects, further elucidating how typhoons influence the natural environment through complex physical processes. Scientific topics, on the other hand, primarily focus on the analysis of typhoon formation mechanisms, structural characteristics, and path prediction, providing scientific insights for the public and policymakers that are essential for a deeper understanding of the complexities and multifaceted impacts of typhoons. Between 2011 and 2020, the distribution of subjects in typhoon news reports shows a significant imbalance, reflecting the widespread impact of typhoons on social, economic, and political domains. As mentioned earlier, typhoons, as extreme meteorological phenomena, have profound effects on ocean temperature distribution and thermal structures,

particularly in shallow and deep ocean layers. Correspondingly, the impact of typhoons on society is also clearly reflected in news coverage. The distribution of subjects in typhoon news reports reveals that \"human\" subjects overwhelmingly dominate the coverage, comprising 86.07% of the total, with a sum of 1396 reports. Figure 7 illustrates this, showing that government workers are the most frequently reported group, with 1150 reports, representing 70.9% of the total. These reports primarily focus on government decisions, meetings, and policy implementation in response to typhoons, highlighting the central role of the government in disaster management and its leadership in post-disaster reconstruction and emergency response.
