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

通常，降水系统被组织成带状结构。这些结构包括与低气压中心相关的飓风雨带和降水带。通常最大的降水发生在这些带上。人们认为带状结构与大气中的不稳定有关，这种不稳定被称为条件对称不稳定(CSI)。使用先进的数值模式，首席调查员将继续进行一系列研究，包括评估各种大气强迫项及其如何影响CSI。如果成功，将特别注意辐射和地面强迫项，这项研究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.
