项目摘要

The interactions between mesoscale convective systems (MCSs) and the synoptic scale environment over West Africa are crucial for determining the nature and variability of the weather and climate of the region. In addition to their important role in influencing West African rainfall, the mesoscale and synoptic scale weather systems (African easterly waves, AEWs) also have a key role in mobilizing and transporting dust. General understanding of the scale interactions including their impact on dust is poor and has until now been severely hindered by lack of useful observations. The related overarching aims of this research are: (i) To improve our knowledge and understanding of the interactions between MCSs and the synoptic environment, and (ii) to improve knowledge and understanding of the role MCSs and AEWs play in mobilizing and transporting dust. Intellectual Merit Central to addressing both aims are the special observations that were made as part of the African Monsoon Multidisciplinary Analysis (AMMA), a special observing campaign over West Africa in summer 2006. Of particular importance to this research are the observations from the MIT Doppler radar. These observations will be used by the PIs to highlight the nature and variability of the intensity and structure of the MCSs. A particularly novel aspect of this work is the estimation of the 4-dimensional diabatic heating fields associated with the MCS passages. The impact these heating fields have on mesoscale potential vorticity structures will be investigated by imposing diabatic heating fields (guided by the observations) in an idealized version of the WRF regional model. A case study will be carried out that explores the multi-scale aspects of the PV field associated with the passage of an AEW and embedded MCSs during the summer of 2006 - something that has not been possible previously. The MIT radar data will also be combined with several ARM (Atmospheric Radiation Measurements) observations, including the 95 Ghz vertically-pointing Doppler radar, to explore in detail how the dust is mobilized in association with the passage of the MCSs. This analysis will be compared to the nature of the synoptic environment, discussed above, and will help to shed light on the relative contributions of Sahelian and Saharan dust to the total dust amounts observed over West Africa (and the tropical Atlantic). Broader impacts The research has broad impacts that include:- Improving knowledge and understanding of the key weather systems in the West African Monsoon. - Educating and training three graduate students who will develop their understanding of weather and climate as well as their skills in data analysis and modeling. - Contributing to knowledge of how the variability of West African weather climate impacts downstream tropical cyclogenesis, through providing detailed analysis of the weather systems before they reach the tropical Atlantic and head for the U.S.
中尺度对流系统(MCSs)和天气尺度环境之间的相互作用,在西非地区的天气和气候的性质和变率的决定是至关重要的。除了在影响西非降雨方面发挥重要作用外,中尺度和天气尺度天气系统(非洲东风波,AEW)在调动和输送沙尘方面也发挥着关键作用。对尺度相互作用包括它们对尘埃的影响的一般理解很差,到目前为止,由于缺乏有用的观测,这一理解受到严重阻碍。 这项研究的相关总体目标是:(一)提高我们的知识和理解的MCS和天气环境之间的相互作用,(二)提高知识和理解的MCS和AEW在动员和运输灰尘的作用。对实现这两个目标至关重要的是作为非洲季风多学科分析(AMMA)的一部分进行的特别观测,AMMA是2006年夏季在西非进行的一次特别观测活动。对这项研究特别重要的是麻省理工学院多普勒雷达的观测。PI将使用这些观察结果强调MCS强度和结构的性质和变异性。这项工作的一个特别新颖的方面是4维非绝热加热场与MCS通道的估计。这些加热场对中尺度位涡结构的影响将通过在WRF区域模式的理想化版本中施加非绝热加热场(由观测结果指导)来研究。将进行一项案例研究,探讨与2006年夏季空中预警和嵌入式MCS通过相关的PV场的多尺度方面-这在以前是不可能的。麻省理工学院的雷达数据还将与几个ARM(大气辐射测量)观测相结合,包括95 Ghz垂直指向多普勒雷达,以详细探索尘埃如何与MCS的通过相关。这一分析将与上文讨论的天气环境的性质进行比较,并将有助于阐明萨赫勒和撒哈拉沙尘对西非(和热带大西洋)上空观测到的沙尘总量的相对贡献。更广泛的影响这项研究具有广泛的影响,包括:-提高知识和理解的关键天气系统在西非季风。- 教育和培训三名研究生,他们将发展对天气和气候的理解以及他们在数据分析和建模方面的技能。- 通过对到达热带大西洋并前往美国之前的天气系统进行详细分析,有助于了解西非天气气候的变化如何影响下游热带气旋生成。
