初始涡旋 meaning in English
initial vortex
Examples
- This paper discuss the effect of roughness coefficient on the tropical cyclone landfalling process using a idealized tc model developed from psu / ncar mm5 in the condition of quiescence and f - plane atmosphere . in order to understand the different influences of land and sea surfaces in the tc landfalling process , two kind of experiments had been designed : one for settled tc , the other for movable tc , and each kind consists four tests . the result indicates that the distribution of wind , precipitation , warm core and intensity of tropical cyclone has been changed obviously due to the effect of difference between the land and sea
本文利用bogus技术在psu / ncarmm5中加入了理想热带气旋初始涡旋，在f -平面和无环境流场的理想情况下，设计了两组静态和动态试验，通过控制试验和不同粗糙度的登陆试验，分别从空间和时间上探讨了理想热带气旋的登陆规律和分布特征，特别研究了边界层中热带气旋中心区域风场的垂直细致结构，并初步分析了其物理机制。 - In this paper , a bogused vortex with tilted vertical structure is firstly taken into account . check results of experiment b , experiment bt and experiment nb , we find that the simulated tc track , center pressure and pattern of precipitation during landing in experiment b are better than others . so , a bogused vortex with asymmetrical horizontal structure and tilted vertical structure is good for a tc moving in mid - latitude , which may be a new way to initialize this kind of tc in numerical simulation
本文首次采用倾斜垂直结构的人造热带气旋作为初始涡旋，试验b和试验bt以及试验nb的模拟结果对比发现，前者对9806号热带气旋登陆前后的运动路径、中心气压、降水分布和初始结构的模拟能力优于后两者，因此，具有倾斜垂直结构的人造热带气旋比正压结构的人造热带气旋更适合于作为模拟中纬度运动的热带气旋的初始涡旋，从而提出解决该类热带气旋初始化问题的一种新思路。
