Since the 1990s, the physical mechanism of tropical cyclone intensity change has been a forward topic of typhoon dynamics.
二十世纪九十年代以来，热带气旋强度变化的物理机制成为国际台风动力学的一个研究热点。
In this paper the parameter and some physical factors, which reflect the intensity change of tropical cyclone, are derived from dynamical and thermodynamics equations.
本文从动力-热力学方程出发。得到反映热带气旋强度变化的参数和几个物理因子。
When the tropical cyclone moves in low latitudes, the cold air from higher latitudes can modulate the intensity of the tropical cyclones.
当热带气旋仍在热带海洋上，冷空气与热带气旋相向而行，气压梯度增强可明显加强热带气旋强度。
Some discussions on how the concentric eyewall structure affects the intensity of tropical cyclone are also proposed.
最后还据此对同心双眼结构的出现和消失如何影响热带气旋强度变化进行了探讨。
In addition, hourly analysis of current intensity of tropical cyclone will be made available in the bulletin for current weather whenever local tropical cyclone warning signal is in force.
除此以外，当本地热带气旋警告信号生效时，热带气旋强度分析资料会每小时附加在天气报告内。
Tropical cyclone tracks and intensity change are two important aspects in typhoon forecast.
热带气旋路径及强度变化是台风预测的两个主要方面。
Tropical cyclone tracks and intensity change are two important aspects in typhoon forecast.
