尘暴是火星表面沙尘颗粒在剧烈的大气运动下形成的扬尘现象,局部尘暴可持续几个火星日(sols),大型甚至全球性尘暴可持续长达几个月.火星尘暴事件严重威胁探测器着陆过程的安全性,并可能加剧火星车太阳能帆板表面的沙尘沉积进而导致火星车供电不足.为保障火星探测任务着陆过程的安全,应开展火星尘暴事件的时空概率分析并对着陆前的尘暴事件进行预报.本文以中国首次火星探测任务“天问一号”为例,开展了:(1)基于长时间序列(MY24~28)火星遥感影像(MDGMs)来提取尘暴对象和尘暴序列,建立乌托邦平原(Utopia Planitia)研究区的尘暴时空数据库;(2)计算研究区中尘暴出现的时空概率,并对“天问一号”任务的着陆时间、地点以及“祝融号”火星车工作和休眠期内的尘暴活动进行分析评价;(3)完成“天问一号”主选和备选着陆圆的原生尘暴划分和尘暴序列的特征提取,并实现了“天问一号”任务着陆前的尘暴预报分析.未来应当结合大气环流模型模拟和计算的大气物理等参数(温度、压强、光学深度、风速和风向等)来综合研究尘暴等大气活动的机理和影响因子,以提高尘暴分析和预报的准确性以及实时性.

We present observations of the eruption of a large-scale quiescent filament （LF） that is associated with the formation and eruption of a miniature filament （MF）. As a result of convergence and subsequent cancelation of opposite-polarity magnetic flux, MF was formed just below the spine of the LF＇s right seg- ment. Probably triggered by a nearby newly emerging flux, MF underwent a failed eruption immediately after its full development, which first ejected away from the spine of LF and then drained back to the Sun. This eruption no sooner started than the overlying LF＇s right segment began to rise slowly and the LF＇s other parts were also disturbed, and eventually the whole LF erupted bodily and quickly. These observa- tions suggest that the MF can serve as an intermediary that links the photospheric small-scale magnetic-field activities to the eruption of the overlying large filament. It appears that, rather than directly interacting with the supporting magnetic field of LF, small-scale flux cancelation and emergence in the LF＇s channel can manifest themselves as the formation and eruption of MF and so indirectly affect the stability of LE

This paper deals with the construction of anisotropic curl-free wavelets on the cube [0,1]3, which satisfies the specific boundary conditions. First, one constructs curl-free wavelets on the unit cube based on one dimensional wavelets on the interval [0,1] with some boundary conditions. Then, the stability of the corresponding wavelets in curl-free space and the characterization of Sobolev spaces are studied. Finally, one gives a Helmholtz decomposition and the representation of curl and div operators in wavelet coordinates.
