A Study of the Effect of a Time-Varying Moist Potential Vorticity on the Evolution of Conditional Symmetric Instability

降水系统通常被组织成带状结构。这些结构包括飓风雨带和与低压中心有关的降水带。通常最强烈的降水发生在这些波段。人们认为，带状结构与大气中的不稳定性有关，即条件对称不稳定性（CSI）。利用先进的数值模型，首席研究员将继续进行一系列研究，包括评估各种大气强迫条件以及它们如何影响CSI。如果这项研究取得成功，将对带状降水结构提供更好的理解和潜在的更好的预测。

Often precipitation systems are organized into banded structures. These structures include hurricane rainbands and precipitation bands associated with low pressure centers. Often the heaviest precipitation occurs in these bands. It is believed that banded structures are associated with instabilities in the atmosphere know as conditional symmetric instability (CSI). Using an advanced numerical model, the Principal Investigator will continue a line of research that involves assessing various atmospheric forcing terms and how they effect the CSI. Special attention will be paid to radiation and surface forcing terms If successful, this research will provide better understanding and potentially better prediction of banded precipitation structures.
