1县级防雷工作的内容1.1防雷行政管理防雷行政管理是县气象局行政管理十分重要的环节,也是气象行政管理的主要内容。县气象局的三个行政许可项目中防雷占了两个。但防雷工作在县气象局刚刚开展,社会和部门在认知上还有一个过程,需做大量艰苦的工作。县气象局应明确“防雷行政管 相似文献

1 防雷行政管理工作的历史和现状 陕西防雷工作起步于1989年,十几年来,历经坎坷,不断发展壮大.防雷工作的内容由最初单纯的检测技术服务,逐步扩大为雷电技术防护、雷电预警预报、雷击风险评估、防雷装置设计审核和竣工验收以及行政许可等,防雷社会管理由最初与公安、劳动、保险等部门合作借力发展,发展到现在运用法律独立行使管理职能,防雷社会管理工作的地位由过去从属地位发展到成为行业管理主体,防雷社会管理工作机构从无到有,发展到现在全省各级防雷管理机构规范设置,执法工作受到各级领导重视,得到快速发展. 相似文献

Summary Considering the effects of causal mechanics on geophysical problems enables us to explain a number of phenomena, which cannot
be explained from conventional positions. This paper shows that the introduction of the force of causality in a simple barotropic
hydrodynamic model of weather forecasts results in the outcomes, which, on the one hand, can not be described from the positions
of classical hydro-thermodynamics, whilst on the other hand, exist in nature. 相似文献

Due to the complex orography and the presence of the moisture-saturated air, the Mediterranean region is characterized by
the increased baroclinic and convective instability, that leads to the sudden cyclogenesis and the formation of dangerous
weather phenomena. The results are given of the investigation of formation mechanisms of Mediterranean cyclones, peculiarities
of stages of their evolution and dynamical processes, which occur throughout the atmosphere, using the regional numerical
ETA model of the atmosphere by the example of individual cases of the cyclogenesis over the Mediterranean Sea. It is revealed
that the cold Arctic air outbreak (the intrusion of the cold Arctic air) to the south of the Western Europe, leading to the
formation of the areas of the baroclinic instability and the increased moisture content of the air in the area of the vortex
origin, favors the cyclogenesis. The use of the vertical coordinate η in the model enabled to compute more precisely the vertical
wind speed, therefore, the influence of the orography on the moisture content and precipitation increase became pronounced.
The transformation of the structure of meteorological fields in the course of the development of vortexes is considered. The
computation of the helicity is made, and it is shown that this characteristic can be one of the earliest predictors of cyclogenesis. 相似文献

Here, we analyze the characteristics and the formation mechanisms of low-level jets(LLJs) in the middle reaches of the Yangtze River during the 2010 mei-yu season using Wuhan station radiosonde data and the fifth generation of the European Centre for Medium-Range Weather Forecasts(ERA5) reanalysis dataset. Our results show that the vertical structure of LLJs is characterized by a predominance of boundary layer jets(BLJs) concentrated at heights of 900–1200 m.The BLJs occur most frequently at 230... 相似文献

On the determination of the height of the Ekman boundary layer 总被引:1,自引:1,他引:1
S. S. Zilitinkevich 《Boundary-Layer Meteorology》1972,3(2):141-145
The heighth
of the Ekman turbulent boundary layer determined by the momentum flux profile is estimated with the aid of considerations of similarity and an analysis of the dynamic equations. Asymptotic formulae have been obtained showing that, with increasing instability,h
increases as ¦¦1/2 (where is the non-dimensional stratification parameter); with increasing stability, on the other hand,h decreases as –1/2. For comparison, a simple estimate of the boundary-layer heighth
u
determined by the velocity profile is given. As is shown, in unstable stratification,h
u
behaves asymptotically as ¦¦–1, i.e., in a manner entirely different from that ofh

流场配置及地形对西南低涡形成的动力作用 总被引:10,自引:8,他引:10
本文采用定常二层模式讨论较小地形及高、低层流场配置对西南低涡形成的动力作用。指出了西南低涡的形成是与盆地、河谷以及其上气流分层有关的一种定常态.在上、下为西风分层时期,低层的浅薄暖湿西风有利于西南低涡的形成.在上、下为东、西风分层时期,上层浅薄东风亦有利于西南低涡的形成.小型的凸起山脉对西南低涡的形成没有作用. 相似文献

1引言我国执行接地降阻剂测试的技术标准是全国电力系统起草的:“接地降阻剂暂行技术条件修改稿”。在技术要求中要求接地降阻剂的酸碱值应在7 ̄12范围内。在实际使用中发现该技术要求对接地降阻剂的酸碱值要求范围并不合理,需要分析和讨论。2接地降阻剂的PH值接地降阻剂的酸碱性对地网的使用寿命至关重要,为了不让接地降阻剂腐蚀接地体或者减弱接地降阻剂对接地体的腐蚀,在接地降阻剂测试的技术要求中,对接地降阻剂的酸碱度有一定的限制。国内各厂家用于生产接地降阻剂的偏弱酸的盐类进行了对镀锌钢材腐蚀的试验,结果是这些镀锌钢材均受到… 相似文献

Summary ?Some features of the climate system that can be considered predictors of the onset and end of the convective season over
the Amazon were identified using one-month lag correlations and field composites. The fields analyzed were sea surface temperature
(SST), outgoing long-wave radiation (OLR), vertical velocity and upper tropospheric winds.
Warm (cold) anomalies in the SST in the tropical North Atlantic and the Caribbean Sea tend to be associated with delayed (early)
onsets. Likewise, there is a tendency towards a delayed (early) end of the convective season with cold (warm) anomalies in
these ocean regions. In addition, the SST in the cold tongue region of the equatorial Pacific is negatively, though weakly
correlated with the onset date. The signal of this SST is more evident in the case of the end date, which is earlier with
respect to its mean date in most of El Ni?o cases.
The convective activity intensity itself conditions the onset and the end of the convective season, as it is evidenced by
the behavior of the OLR and the vertical velocity fields. The more (less) intense the convective activity over South America
during the preceding month, the earlier the onset and the later the end of the convective season on the Amazon region.
The prediction of the onset and end dates of the convective season in the Amazon region was explored using a simple multiple
regression technique based on the variables that have shown precursor signals with respect to these dates. The correlation
coefficient between the predicted and the observed onset date is 0.81, and in the case of the end date, it is 0.76. The skill
to predict early, delayed and normal categories was high, since in more than two thirds of the cases the category was successfully
predicted, and there were no predictions of categories opposed to those observed.
