As a part of the Tropical Cyclone Rapid Intensification (TCRI) project, we investigated thermodynamic conditions necessary for cyclone intensification. While high sea surface temperature and low tropospheric wind shear are well known environmental factors contributing to storm intensification, they are not sufficient to predict intensification and rapid intensification in particular. To explore thermodynamic factors contributing to intensification, we used dropsondes deployed in pre-storm and storm environments interpolated on a regular grid via a 3D variational analysis. We find that in mesoscale convective areas an instability index, which measures the stability of the atmosphere to moist convection, and saturation fraction, which measures the moisture content of the atmosphere, show a narrow range of values favorable for intensification, and rapid intensification in particular.

热带气旋快速增强所需的对流层热力学条件
作为热带气旋快速增强 (TCRI) 项目的一部分,我们研究了气旋增强所需的热力学条件。虽然高海面温度和低对流层风切变是导致风暴增强的众所周知的环境因素,但它们不足以预测增强,特别是快速增强。为了探索导致增强的热力学因素,我们使用了部署在暴风雨前和暴风雨环境中的空投探空仪,并通过 3D 变分分析在规则网格上插值。我们发现,在中尺度对流区,衡量大气对湿对流稳定性的不稳定指数和衡量大气含水率的饱和分数显示出有利于增强,特别是快速增强的狭窄值范围。
