Theories and Methods for Diagnoses of Moist Frontal Circulations

虽然许多影响天气的因素 模式是相当好理解的，物理现象， 控制局部严重事件，如极重 降雪或山洪暴发仍然是个谜。 气象学家称之为中尺度现象， 目前正在进行紧张的调查， 气象界。 主要研究者将进行理论和 两种中尺度现象的数值模拟研究 （锋生强迫和湿对称稳定性）。 这些 在某些情况下，这些特征可能是形成 强烈的雨/雪带，往往形成在附近的 气象前线 这项研究的结果将导致 更好地理解带状的物理学 沉淀结构，并最终改善短程 降水预测。//

While many of the factors that govern general weather patterns are fairly well understood, the physical phenomena that control localized severe events, such as extremely heavy snowfalls or flash floods, are still somewhat of a mystery. These mesoscale phenomena, as they are called by meteorologist, currently are the subject of intense investigations within the meteorological community. The Principal Investigator will undertake a theoretical and numerical modeling investigation of two mesoscale phenomena (frontogenetical forcing and moist symmetric stability). These features may be responsible in some cases for the formation of intense rain/snow bands that often form in the vicinity of meteorological fronts. Results of this study should lead to better fundamental understanding of the physics of banded precipitation structures and eventually to improved short range precipitation predictions.//
