中文摘要
海洋沉积物的空气成分的化学和矿物学可以用来追踪粉尘的来源位置。根据这些数据,就有可能在过去的某个时刻追踪气团和风的轨迹。本提案要求支持建立太平洋表层沉积物矿物学、气溶胶矿物学和气团轨迹的正式数据库。这些数据可以用来更准确地重建过去的风和气团运动。这项研究很重要,因为对过去风向和强度的重建提供了关于大气如何响应过去气候变化的重要信息。过去的风强度和风向也有助于测试一般环流模式的敏感性,因为风向和风向是这些数值模拟的主要输出。
英文摘要
The chemistry and mineralogy of air-borne components of marine sediments can be used to trace the source location of the dust. From these data it is possible then to trace the trajectory of air masses and winds at times in the past. This proposal requests support to develop a formal data base of surface sediment mineralogy, aerosol mineralogy, and air mass trajectory for the Pacific Ocean. These data can then be used to reconstruct past winds and air mass movements with greater accuracy. The research is important because the reconstruction of past wind directions and intensities provides important information about how the atmosphere responded to past climate change. Past wind intensities and directions also help to test the sensitivity of General Circulation Models, since wind direction and intensity are principal output from these numerical simulations.
