Code for tropical cyclone wind profile model of Chavas et al (2015, JAS)
收藏资源简介:
<p>MATLAB code (+ python version, courtesy of Chia-Ying Lee) to produce the tropical cyclone radial profile of the near-surface rotating wind, defined in Chavas et al (2015, JAS). The model&#39;s representation of wind field variability is described in Chavas and Lin (2016, JAS). The code is&nbsp;fast (runs in &lt;0.1s) and written in a robust manner to handle a very wide range of parameters. The code numerically merges a&nbsp;solution for the inner convecting&nbsp;wind field from Emanuel and Rotunno (2011) with a solution for the outer wind field from Emanuel (2004); each individual solution also require&nbsp;a&nbsp;fast numerical integration as neither is fully analytic.</p> <p>Chavas, D.

本数据集包含用于生成近地面旋转风热带气旋径向廓线的MATLAB代码(附带Python版本,由Chia-Ying Lee提供),该廓线的定义源自Chavas等人2015年发表于《大气科学杂志(Journal of the Atmospheric Sciences,简称JAS)》的研究。该模型对风场变率的表征方式详见Chavas和Lin 2016年发表于JAS的研究。本代码运行速度极快(耗时小于0.1秒),且采用鲁棒性设计,可适配极广范围的参数设置。该代码通过数值方法融合了Emanuel和Rotunno 2011年提出的内对流风场解,以及Emanuel 2004年提出的外风场解;由于两种解均无法完全解析表达,各自的求解过程也需要借助快速数值积分完成。 Chavas, D.
