This study addresses the passage of buoyancy streams within moist air along with the rain bands of a hurricane, Ingrid of September 2013 and Gabrielle of August 2013. Moist air along the rain bands of a hurricane supplies buoyancy to the eyewall where clouds grow during the hurricane's intensifying phase. In order to visualize these buoyancy streams, it was necessary to invoke rain rate initialization referred to as Physical initialization for the model. For Ingrid, physical initialization resulted in a relatively moist boundary layer where the buoyancy stream passages were also noted. It was also noted that the convergence of flux of buoyancy contributes to the confinement of buoyancy elements within the moist stream. Physical initialization provided an improvement for the boundary layer moisture along with the rain bands. In Ingrid, the initial moisture analysis (data assimilation) was a little too dry and was improved by invoking physical initialization that made the boundary layer moist. Computations showed a larger population (area occupied) of the buoyant elements before and after physical initialization. This study's salient aspect relates to a time history of buoyancy over a box where the rain band meets the eyewall of hurricane Ingrid. As many as 5-peaks showing buoyancy flare-ups and vertical stretching were followed with increased storm intensification. Monitoring the time history of buoyant elements and their budget is remarkable in the understanding of growing versus decaying phases of these storms.

快速增强的风暴眼壁中沿雨带的浮力流和云朵爆发

这项研究解决了潮湿空气中浮力流与飓风雨带一起通过的问题，2013 年 9 月的 Ingrid 和 2013 年 8 月的 Gabrielle。沿着飓风雨带的潮湿空气为风眼墙提供浮力，在飓风期间云在那里生长强化阶段。为了可视化这些浮力流，有必要调用降雨率初始化，称为模型的物理初始化。对于 Ingrid，物理初始化导致了一个相对潮湿的边界层，其中还注意到了浮力流通道。还注意到浮力通量的收敛有助于将浮力元件限制在湿流中。物理初始化为边界层湿度和雨带提供了改进。在英格丽德，最初的水分分析（数据同化）有点过于干燥，通过调用使边界层湿润的物理初始化进行了改进。计算表明，在物理初始化之前和之后，浮力元件的数量（占用面积）更大。这项研究的显着方面与雨带与飓风英格丽德眼壁相遇的盒子上浮力的时间历程有关。多达 5 个峰值显示浮力骤升和垂直拉伸，随后风暴强度增加。监测浮力元素的时间历程及其预算对于了解这些风暴的增长阶段与衰减阶段非常重要。计算表明，在物理初始化之前和之后，浮力元件的数量（占用面积）更大。这项研究的显着方面与雨带与飓风英格丽德眼壁相遇的盒子上浮力的时间历程有关。多达 5 个峰值显示浮力骤升和垂直拉伸，随后风暴强度增加。监测浮力元素的时间历程及其预算对于了解这些风暴的增长阶段与衰减阶段非常重要。计算表明，在物理初始化之前和之后，浮力元件的数量（占用面积）更大。这项研究的显着方面与雨带与飓风英格丽德眼壁相遇的盒子上浮力的时间历程有关。多达 5 个峰值显示浮力骤升和垂直拉伸，随后风暴强度增加。监测浮力元素的时间历程及其预算对于了解这些风暴的增长阶段与衰减阶段非常重要。多达 5 个峰值显示浮力骤升和垂直拉伸，随后风暴强度增加。监测浮力元素的时间历程及其预算对于了解这些风暴的增长阶段与衰减阶段非常重要。多达 5 个峰值显示浮力骤升和垂直拉伸，随后风暴强度增加。监测浮力元素的时间历程及其预算对于了解这些风暴的增长阶段与衰减阶段非常重要。
