This paper starts with untime-diversification of the time-diversification deformation model and gives displacement distribution model of untime-diversification and simplifies further the study of deformation model. The paper discusses the problem of least squares fitting of coordinate parameters model—parameters of deformation model. During discussion, the basic means of cubic B splines and two steps of multidimensional disorder datum fitting are adopted which can make fitting function calculated mostly approximate coordinate parameters model and it can make calculation easier.

The moist vorticity vector (MVV), defined as (ζa×▽qv)/ρ introduced by Gao et al. is used to study a heavy rainfall event in North china. The MVV has zonal, meridional and vertical components in a three-dimensional framework. Analysis of domain-mean and mass-integrated quantities shows that the variation of the vertical component of the MVV closely follows the variation of the cloud hydrometeors, with a linear correlation coefficient of 0.95, indicating that the vertical component of the MVV is strongly associated with midlatitude convection. Further analysis shows that the vertical component of the MVV reflects the interaction between the horizontal vorticity and the horizontal specific humidity gradient, which can associate dynamic and thermodynamic processes with cloud microphysical processes. Thus, this study can help to understand how the interaction between circulations and clouds aids the development of convection, and the MVV can be used to trace the development and evolution of heavy rainfall.

通过实施土地开发整理,从根本上改善了农村生态环境,不仅增加了农村耕地面积,促进了农业生产水平的提高和农民增产增收,更有力地促进了农村经济发展。农业生产条件的改善,使生产成本得到有效降低,规模效益普遍提高,壮大了村集体经济实力,加快了社会主义新农村建设步伐。但工作中仍存在领导重视不够、工程质量不够高、后期管护不到位等问题,今后应进一步强化领导、规范运作、跟踪管理,以保证开发整理成效。

利用压力室技术测到的水势是缺乏修正的数值,比实际水势要高出许多,用该方法测定水势,只能反映出水势的大小变化,而不能用其代表木质部内真实的负压。蒸腾使木质部产生的负压最大不会超过-0.1Mpa,木质部内巨大负压的存在缺乏理论依据和直接的实验证据。空穴的必然发生使水柱无法保持连续,故连续水柱不存在。蒸腾状态下木质部水分的移动方式是自上而下分段依次移动的,这一现象与内聚力原理相抵触。蒸腾产生的负压能保持到蒸腾停止后继续使根系吸水。

Detection of nighttime sea fog/stratus over the Huang-hai Sea using MTSAT-1R IR data

引用

Acta Oceanologica Sinica 2009年第2期28卷 23-35页

作者： GAO Shanhong WU Wei ZHU Leilei FU Gang HUANG Bin Physical Oceanography Laboratory Ocean University of China Qingdao 266003 China shandong Provincial meteorological Institute Jinan 250031 China National meteorological Center China Meteorological Administration Beijing 100081 China

A dual channel difference （DCD） method is applied to detect nighttime sea fog/stratus over the Huanghai Sea using the infrared （IR） data of shortwave （3.5-4.0 μm） and longwave （10.3-11.3 μm） channels from the Multi-functional Transport Satellite （MTSAT）-IR, i.e., shortwave minus longwave brightness temperature difference （SLTD）. Twenty-four sea fog events over the Huanghai Sea during March to July of 2006 and 2007 are chosen to determine a suitable value of SLTD for nighttime sea fog/stratus detection, and it is found that the value of-5.5-2.5℃ can be taken as a criterion. Two case examples of sea fog events are especially demonstrated in detail utilizing the criterion, and the results show that the derived sea fog/stratus coverage is quite reasonable. This coverage information is very helpful to analyze the formation and evolution of sea fog/stratus during night and can provide sea fog researchers with observational evidences for model results verification. However, more efforts are needed to further obtain vertical extent information of sea fog/stratus and attempt to discriminate between sea fog and stratus.
