中文摘要
地球环境中的变化受两个主要驱动因素的影响:中低大气的变化主要受源自地表的过程的影响,而高层大气的变化则受太阳变化的控制。传统上,人们使用不同的数值模型来研究这些制度,尽管它们既不是不同的地区,也不是完全独立的驱动因素。来自低层大气的波可能会对高层大气产生很大影响,而太阳的可变性可能会产生严重的影响,至少在平流层中部。TIES项目的目的是弥合气象学和空间科学之间的差距,因为这种大气耦合只有在描述所有相关区域的模型中才能被捕获和理解。一个创新的全大气模式将通过将两个模式结合在一起来创建,这两个模式结合在一起非常好地描述了低层、中层和高层大气。这一工具将用于调查太阳变化对大气的影响。科学重点将放在粒子降水产生的消耗臭氧的NOY物种及其与极地化学和动力学的相互作用,以及通过大气波的垂直耦合传递太阳信号。CAWSES其他项目(ARTOSAIMOS、PROSECCO)的专门知识和数据将有助于这些调查。
英文摘要
The processes in the environment of our planet are governed by two major drivers: The variability of the lower and middle atmosphere is mostly influenced by processes originating at the surface, while the variability of the upper atmosphere is controlled by solar variability. Traditionally different numerical models have been used to study these regimes, although they are neither distinct regions nor completely independent drivers. Waves from the lower atmosphere can have large effects in the upper atmosphere, and solar variability can have severe effects at least down to the middle stratosphere. The aim of the TIES project is to bridge the gap between meteorology and space science because such atmospheric coupling can only be captured and understood in models describing all involved regions consistently. An innovative whole atmosphere model will be created by coupling two models that in combination very well describe the lower, middle and upper atmosphere. This tool will be used for investigations of the impact of solar variability on the atmosphere. Scientific focus will be on ozone depleting NOy species that are produced by particle precipitation and their interactions with polar chemistry and dynamics, as well as the transfer of the solar signal through vertical coupling by atmospheric waves. Expertise and data from other CAWSES projects (ARTOSAIMOS, ProSECCO) will aid these investigations.
