Mesoscale Frontal Waves

气象专家认为，大多数强降水和严重的 天气事件是由发生在所谓的 气象学家称之为风暴尺度或中尺度。 这些 地物的典型空间尺度为10至100公里， 没有很好地被业务天气系统采样， 明白 在与一位来自国家科学院的科学家的合作中， 大气研究中心，首席研究员将 研究已经观测到的发展中的小的中尺度扰动 在大尺度天气锋面上。 主要问题是 要解决的是水动力机制，引起 中尺度波及其与对流的相互作用和影响 它们形成的锋面区域的结构。 的答案 这些问题将加深我们对 降水沿着锋分布和强度 边界 这项研究涉及理论，数值模型和 观察分析 使用的数据是在 两项实地调查集中于中尺度过程， 大西洋低地实验和俄克拉荷马-堪萨斯的起源 STORM-Central初步区域实验（STORM代表 风暴尺度业务和研究气象学）。

Meteorologists recognize that most heavy precipitation and severe weather events are controlled by factors that occur on what is termed the stormscale or mesoscale as it is called by meteorologist. These features have typical spatial scales of 10 to 100 kilometers and are not well sampled by the operational weather system nor well understood. In a collaborative effort with a scientist from the National Center for Atmospheric Research, the Principal Investigator will study small mesoscale disturbances that have been observed to develop on large scale synoptic frontal surfaces. The primary questions to be addressed are the hydrodynamic mechanisms that give rise to mesoscale waves, their interactions with convection and their effect on the structure of the frontal zones on which they form. Answers to these questions will enhance our basic understanding of the distribution and intensity of precipitation along frontal boundaries. This investigation involves theory, numerical models and observational analysis. The data to be used were collected during two field investigations focussed on mesoscale processes -- the Genesis of Atlantic Lows Experiment and the Oklahoma-Kansas Preliminary Regional Experiment for STORM-Central (STORM stands for Stormscale Operational and Research Meteorology).
