为了更好地解决核应急救援航空辐射监测队伍能力评估指标中的不确定性、提高核应急航空辐射监测能力评估准确性,在构建评估指标体系的基础上,将层次分析法(AHP)与模糊综合评价法(FCE)有机结合,建立核应急航空辐射监测能力评估模型。该模型根据核应急航空辐射监测队伍应急准备、应急响应、应急救援、总结分析情况,综合各要素关键评估内容,形成了以核应急航空辐射监测能力为总目标,下设4项一级指标和16项二级指标的核应急航空辐射监测能力量化评估模型;通过AHP法计算指标权重,采用FCE法计算综合得分,实现对核应急航空辐射监测能力的综合量化评估。通过实例验证表明,AHP-FCE模型具有良好的适应性与合理性,为核应急救援航空辐射监测队伍能力评估提供参考。

This study investigates the relationship between the persistence and the zonal scale of atmospheric dipolar modes(DMs). Results from the daily data of ERA5 and the long-term output of an idealized atmospheric model show that the atmospheric DMs with a broader(narrower) zonal scale dipolar structure possess a longer(shorter) persistence. A detailed vorticity budget analysis indicates that the persistence of a hemispheric-scale DM(1/1 DM) and a regional or sectoral DM(1/8 DM) in the model both largely rely on the persistence of the nonlinear eddy forcing. Linear terms can indirectly reduce the persistence of the anomalous nonlinear eddy forcing in a 1/8 DM by modifying the baroclinicity via the arousal of anomalous vertical motions. Therefore, the atmospheric DMs with a broader(narrower) zonal scale possess a longer(shorter) persistence because the effects of the linear terms are less(more) pronounced when the atmospheric DMs have better(worse) zonal symmetry. Further analyses show that the positive eddy feedback effect is weak or even absent in a 1/8DM and the high-frequency eddy forcing acts more like a concomitant phenomenon rather than a leading driving factor for a 1/8 DM. Thus, the hemispheric-scale DM and the regional or sectoral DMs are different, not only in their persistence but also in their dynamics.
