石家庄市强暴雨的气候特征和环流形势分析 总被引:2,自引:1,他引:2
利用统计学方法对石家庄及各市(县)建站以来的强暴雨过程进行气候分析。普查了59次强暴雨个例的历史天气图,将强暴雨过程分成8个类型,归纳出各型强暴雨的发生时段和落区;找出各型的典型形势场特征,并制作了天气型模板,可在MICAPS平台上直接与天气图叠加,进行预报分析,力图以此提高预报强暴雨的能力。 相似文献

Despite the small size of England and Wales, the rainfall there shows large variations, possibly due to geographical and topographical conditions. Spectral analysis shows a large number of periodicities, but many are statistically insignificant, indicating considerable randomness. Significant periodicities are invariably in the low periodicity region (periodicity < 5 yr). Occasionally, high periodicities are also encountered, but are always accompanied by low periodicities. Hence, meaningful predictions are not possible. 相似文献

Technology of space monitoring of the state of water bodies and results of its application for studying the Azov-Black Sea basin in 2008 are considered. Based on the processing of more than 1000 satellite images and ground-based station data, basic characteristic features of the marine environmental pollution are determined which are connected with suspension dispersion, phytoplankton and algae growth, ship dumping of oil products (more than 62 oil patches were revealed), etc. The influence of dynamic structures in the coastal zone on the spatiotemporal distribution of the sea surface pollution parameters, and their contribution to mechanisms of water purification and self-purification are estimated. In particular, new data are obtained about the evolution of “Caucasian anticyclones,” about the dates of intensification of the Main Black Sea Current, and about features of coccolithophore bloom in the abyssal area of the Black Sea, etc. 相似文献

In conventional gradient-transfer models of the atmospheric boundary layer, the fluxes are calculated using the gradients of buoyancy and momentum over the grid interval. When using finite-differences, these gradients are approximated using what are essentially the grid-volume means of the quantities involved. This is unrealistic, as within a large volume of the atmosphere fluxes are supported by an ensemble of small-scale motions, which may be organized by the presence of large coherent eddies. In this paper, a new method of computing the flux is developed, in which the gradients of grid-volume mean buoyancy and momentum are replaced by grid-volume ensembles. The distributional parameters of the ensembles are derived using dimensional arguments, augmented by the results of a large-eddy simulation. 相似文献

Statistical processing of simultaneous multiyear field observations of biogenic pollutants and water discharges in a small river is carried out for the northwestern region of Russia. Stress (in terms of water pollution) periods are found. Estimates of the distribution parameters are considered, results of autocorrelation and correlation analyses are presented, and the results obtained are discussed. 相似文献
