对陆地上热带低强度的数值模拟进行了分析。使用 MM5 介观模型进行模拟，初始条件和边界条件由 ECMWF 分析提供。讨论了七种模拟：一种控制模拟、五种灵敏度模拟（其中初始水分可用性变化）以及一种模拟（其中水分可用性之间的耦合被抑制）。改变初始水分可用性为深层对流的发展增加了随机因素。结果根据最近修改的热带气旋增强的经典轴对称范式进行解释。
An analysis of numerical simulations of tropical low intensification over land is presented. The simulations are carried out using the MM5 mesoscale model with initial and boundary conditions provided by ECMWF analyses. Seven simulations are discussed: a control simulation, five sensitivity simulations in which the initial moisture availability is varied, and one simulation in which the coupling between moisture availability is suppressed. Changing the initial moisture availability adds a stochastic element to the development of deep convection. The results are interpreted in terms of the classical axisymmetric paradigm for tropical cyclone intensification with recent modifications.
