大气层结稳定度 的翻译结果
In this paper, using least square method instead of similarity hypothesis of profiles between wind and temperature, We analyse data of mean wind and temperature obtained from a meteorological tower at Beijing over rough and inhomo-geneous terrain in stable stratified condition.The results show that the rule of log+linear is valid and true within the wide limits of the stable stratification from slight stablity to strong inversion and that the profile parameters (βu and β(?)) are not constants, but vary with...
In this paper, using least square method instead of similarity hypothesis of profiles between wind and temperature, We analyse data of mean wind and temperature obtained from a meteorological tower at Beijing over rough and inhomo-geneous terrain in stable stratified condition.The results show that the rule of log+linear is valid and true within the wide limits of the stable stratification from slight stablity to strong inversion and that the profile parameters (βu and β(?)) are not constants, but vary with atmospheric stratification condition. The experimental formulae shown here indicate that the profile parameters decrease with incresing of Ri and increase with L. The variation of profile parameters with stability in condition Ri>Riet differs from in condition Ri
本文不做风和温度廓线相似性假设,使用最小二乘法分析位于粗糙、不均匀地形上北京气象专用塔在稳定条件下的平均风速和温度测量资料。结果表明,在近地面层,从弱稳定到强逆温的较宽的稳定层结范围内,对数加线性规律都是适用的;廓线参数β和β不是常数,它们的数值随大气稳定度而变化。文中给出的经验公式表明:廓线参数随R_i的增大而减少,随L的增大而增大。在临界理查逊数的两侧,廓线参数随R_i的变化遵循不同的规律。文中还表明,廓线相似性假设仅对大气层结稳定度较弱时才是真实的;当稳定度增大时,廓线变成不相似,P值随R_i的增大而增大。
The South China Sea is one of the tropical seas with high SST, and its seasonal and non-seasonal variations of SST are both conside-rable.It is found that SST variations of the central-north part of the South China Sea have a significant effect on the sea-air heat exchanges and the atmospheric stability.The central-north part of the South China Sea, as an underlying heat source,is responsible for the long-term weather anomalies.

The analyses in this paper deal with: (1) the regional distribution and inte-rannual variations for the occurrences of severe convective storms in March and April in Guangdong, and( 2) the correlation between the mean stability for stratified atmosphere in South China and the surface thermal condition during the same season. It concludes that a long-term forecast of the convection occurrences for the time can be converted to a forecast of thermodynamics for the lower atmosphere. Further exploitation reveals...

It concludes that a long-term forecast of the convection occurrences for the time can be converted to a forecast of thermodynamics for the lower atmosphere. Further exploitation reveals that Southern Oscillation, SST in the South China Sea,and intensity of the West Pacific Sub- tropical High are important restraints for spring temperature in Guangdong, stratification stability and occurrence variations of severe convection. The conclusion is used to develop a physically significant statistics equation for predicting the variation tendency of the occurrence for severe spring convection in Central and West Guangdong. It works well.
濮梅娟(省气象局副局长、新闻发言人):大气污染的影响跟气象条件密切相关,气象部门制定了江苏省环境气象相关实施方案,进一步建设完善大气污染监测网络,提升大气污染预警服务能力,主要在三个方面加强工作:一是建立完善大气污染监测预警业务,开展大气污染气象条件预报,通过加强大气污染气象条件监测,包括常规气象要素,雾霾的监测等等,分析研究大气污染的天气背景、影响系统,以及它对大气污染的影响的关系大气层结稳定度,建立大气污染气象条件的预报系统,对大气污染气象条件做出不同等级预报,预判未来的天气是否有利于空气的污染、扩散和清除。提升大气环境质量预报和污染预警水平大气层结稳定度,强化污染源追踪与解析,开展大气环境质量预报。我们所能直接看到的是位于太阳表面的光球层.光球层比较活跃,温度约为摄氏六千多度,属于比较“凉爽”部分.光球层上有一个个起伏的对流单元“米粒”.每个米粒的直径在一千六百公里左右,它们是一个个从太阳内部升上来的热气流的顶问.就是在不断的对流活动中,太阳每秒钟向宇宙空间释放着相当于一千亿个百万吨级核弹的能量.。
