降水

The effects of sunshine and precipitation on phenology phase changes are different because of the difference of the geographical location and the growing phases.

日照和降水对物候期变化的影响，由于其地理位置和生育时段的不同而呈现各不相同的关系。

The autumn rainfall had showed decrease trend, and winter was pluvial period in 1970's, summer was pluvial period in 1980's, spring was infrequent rain period in 1970's.

秋季降水呈下降趋势，而冬季在20世纪70年代为多雨期，夏季在80年代为多雨期，春季在70年代为少雨期。

The result of factor analysis can provide the changes of relative precipitation and temperature variations. In trace elements, Cu, As, Zn, Pb and Ni were apparently enrichmented in soil layers and are sensitive to climatic changes. Carbon isotope is more sensitive to climatic changes than that of oxygen isotope in loess stratigraphy. The heavy mineral are varified in the loess stratigraphy, but their content differences between loess and palaeosol is little. Though the palynologic analyses results reveal that pollens and spores are fewer in the loess stratigraphy, they differ greatly in loess layer and palaeosol layer not only in species but also in types, i. e., the pollens and spores indicating warm and moist climate, such as Lles, Podocarpus, Polopydium, Pteris grerilliana Wall, Pterocarya and Juglans appear in palaeosol layers, while those indicating cold and dry climate such as Ephedra, Artemisia, Chinopodiaceae, Picea and Abies exist mainly in loess layers. The pollen content of broad-leaved tree mainly consisting of Pterocarya is up to 60% in palaeosol 〓, while the content of Ephedra is more than 50% in 〓 loess layer, showing that the environment differed greatly when 〓 and 〓 were formed.

当然，常量元素氧化物的组合因子分析结果可提供相对降水与相对温度在剖面的变化，因而来反映气候状况更为理想；微量元素中Cu、As、Zn、Pb与Ni在成土过程中富集明显，亦较好地反映了气候变化；稳定同位素中的碳同位素比氧同位素更能敏感记录气候的变化；研究区黄土地层中重矿物种类较多，但黄土层与古土壤层中含量差异不大；孢粉分析结果揭示，尽管研究区黄土层中孢粉总量相对较为贫乏，但黄土层与古土壤层中孢粉种属相差较大：在古土壤层内出现了指示相对暖湿环境的冬青属、罗汉松属、水龙骨属、林下凤尾蕨、枫杨、胡桃等植物孢粉，而黄土层中麻黄、藜科、蒿属及冷杉、云杉含量较高。

Based on analyzing the causes of flood and the relationship between variation rate of sunspot and precipitation, the point of view of energy variation continuity is put forward, and it is used to analyze the energy process related to precipitation.

基于对洪水发生原因以及太阳黑子变化率与降水量关系的分析结果，初步提出了从某一地区能量以及能量连续变化的观点，来分析与降水有关的能量过程。

Collected data showed that soil water status of peanut slope farmland changes along with periods of year rainfall, and location of slope farmland. The 0~150cm soil pondage is divided into three stages that are water surplus period, water consume period and water complementarities period.

花生旱坡地水分状况随年降水周期和坡位不同变化。0~150cm土壤贮水量大致分为盈余期、消耗期和补充期三个阶段。

In chapter 5, the method of Power Spectrum was used to analyze the cycle change of precipitation and temperature each station.

第五章采用功率谱方法分析了各站点降水和气温的周期变化。

Relationship Between Gps Precipitable Water Vapor And Precipitation.

Previous study shows that GPS precipitable water vapor and local precipitation have close relationship.

该文利用 2 0 0 2年"973"项目安徽GPS外场试验和 2 0 0 0年北京GPS/VAPOR试验积累的资料对GPS遥感的大气可降水量与局地降水之间关系进行了定量分析。

The particles act as seeds or nuclei for precipitable water drop formation, thereby to enhance precipitation from the cloud formation.

粒子作为种子或细胞核为降水量下降的形成，从而提高降水从云的形成。

It indicates that the precipitable water changes remarkably with seasons and precipitation mostly occurs in the period when precipitable water is larger than its threshold value.

结果表明，GPS反演的大气可降水量具有较高的使用价值，其时空变化明显，反映了河北降水的季节和地区变化特征。
