[目的]为检验中国气象局风能太阳能预报系统(CMA-WSP)风速产品在风资源短期预报中的可靠性,对CMAWSP 100 m风速3 d预报产品进行检验分析。[方法]文章利用湖北省枣阳周楼、麻城蔡家寨和大金中部3个风电场100 m风速实测数据开展研究。[结果]研究结果如下:(1)CMA-WSP对枣阳风电场3 d内风速的整体预报效果较好,预报结果与实测风速变化趋势较为一致,逐15 min、小时平均和日平均风速第1 d的预报与实测风速相关系数可达0.728、0.740和0.860,随着预报时效增加,预报与实测相关性逐渐降低。(2)CMA-WSP预报风速与实测风速相对误差变化规律性强,逐15 min、小时平均和日平均风速第1 d预报相对误差分别为68%、70%和92%,预报风速整体高于实测风速;小时平均风速及相对误差均呈现白天小、晚上大的特征;月平均风速变化与MRE值变化呈相反趋势,且在1~6月和10~12月最低、7~9月最大。(3)从地区差异来看,CMA-WSP对枣阳周楼风电场风速的预报效果最好,第1 d预报与实测风速相关性可以达到0.728,第2~3 d的预报相关性也超过0.6,CMA-WSP对蔡家寨和大金中部风电场的预报与实测风速相关系数均低于0.6。[结论]CMA-WSP风速预报效果整体较好,且相对误差具有一定的规律性,有利于下一步对该产品进行订正、降低误差水平。

Objective: We assess the application effect of the “3 + 1” mode in the COVID-19 epidemic prevention and control at the infection ward of a designated comprehensive hospital for COVID-19 treatment. Method: Based on the features of the inpatients of the infection ward and their relatives, a “3 + 1” mode for the COVID-19 prevention and control is developed to conform to the demands for epidemic prevention and control and the overall prevention and control scheme of the whole hospital. Here, “3” stands for the epidemic prevention and control system, personnel management, and prevention and control measures;“1” stands for COVID-19 testing. Result: From March 1, 2020 to March 31, 2021, a total of 3056 patients were hospitalized in the three infection wards. Among them, 265 patients had a fever, and 113 patients had respiratory symptoms. None of them were infected with COVID-19. The participation rate of the test about the knowledge related to COVID-19 and the knowledge mastery rate were both 100% among the medical staff. None of the inpatients and their companions or the medical staff was diagnosed with COVID-19. Conclusion: Thus the “3 + 1” mode proves successful for avoiding nosocomial infection and the spread of the epidemic.

In this study, the five-in-one community mass prevention and mass treatment group established in Wuhan to curb novel coronavirus outbreak in 2019 to 2020 is introduced. Various public health propaganda methods are used, including community loudspeakers and community bulletin boards. In the meantime, WeChat platform account named “Wuhan neighborhood on WeChat” is registered and opened, and a Group Chat on WeChat is created for grid management. A diversity of on-line and off-line countermeasures against the novel coronavirus outbreak are implemented via the WeChat platform: three-early measures (early discovery, early reporting, and early treatment), centralized management, community-based reporting, hierarchical diagnosis, and treatment system, isolation of mild patients at designated facilities, diagnosis and treatment appointment system for patients with fever, patient transferral in special vehicles, terminal disinfection at homes, psychological support and daily caring plan for special populations. This WeChat platform allows for an all-region, all-around, all-time and entire population-coverage control of novel coronavirus outbreak, with the extension and strengthening of health propaganda, guidance for seeking medical assistance, mass prevention and mass treatment, and health self-management among the community residents. Great effect has been achieved in novel coronavirus control so far. The five-in-one community management mode of Wuhan plus “Wuhan neighborhood on WeChat” plays an important role in relieving the shortage of health service resources and resolving the problem of limited service scope of professional medical staff in Wuhan, and ultimately contributes to the overall novel coronavirus control.
