| 1. | We also detail regional range of each season . and chose 4 stations to analyze the decadal variability of rainfall 最后选取4个代表站进行降水的年代际变化分析。 |
| 2. | Representatives of each race stood in their appropriate places and spoke to their own guardianship on behalf of their people 而各种族的代表站在所属的位置以代表人民守护的身分发言。 |
| 3. | In this paper tendency analysis method is used to analyze the trend of annual and seasonal rainfall at 35 stations of fujian from 1961 to 2003 摘要本文应用趋势分析方法分析了福建省35个代表站1961 ~ 2003年年、季降水的变化规律。 |
| 4. | 29 representative stations of northwest china are selected using eof analysis , and the detailed results of characteristics are given for temporal and space variation of interarmual change and decadal change . the main conclusions are followed : ( 1 ) the tendency of precipitation in northwest china is positive to the west of 103 e longitude and opposite to the east of it . there is a periodic oscillation of quasi - three years of precipitation and a mutation in the middle of 80s in spring precipitation of northwest china 用eof分析方法选取西北地区29个代表站,分别对其春季和夏季近50a降水进行年际变化和年代际变化时空特征分析,结果发现( 1 )西北地区近50a降水时空趋势变化以103 e为基准线,以西为正,以东为负,并有准3a的振荡周期, 80年代中期西北地区春季降水出现了气候突变。 |
| 5. | In order to provide scientific advice for wintertime agricultural production in guangdong province , we analyzed and studied the yearly variations and spatial distribution of the winter chilling damage in guangdong for the latest 44 years by using mean daily temperature and daily minimum temperature of 22 meteorological stations in guangdong from december , 1957 to february , 2001 用广东省22个分布较均匀的代表站1957年12月? 2001年2月冬季( 12月? 2月)逐日平均气温和最低气温资料,对广东省近44年来冬季寒害的发生规律及地域分布特征进行了分析和研究,为广东省冬季农业生产提供科学指导。 |
| 6. | The precipitation and evaporation data at 12 observational stations from 1958 to 2003 were used to calculate the spring drought index , the criterion of spring drought and the spring drought index series were set up , the spatial and temporal features , yearly and decadal climate variability of the indexes of the loess plateau in gansu province were analyzed 摘要利用甘肃省甘肃黄土高原地区12个代表站1958 ~ 2003年春季3 ~ 5月逐候降水、蒸发资料,建立了该地区早春旱和晚春旱指数序列,确定了春旱等级标准,进一步分析了春旱的时空分布特征及其年际(年代际)变化规律。 |
| 7. | The correlativity between theoretical value and the actual value of soil moisture content in 93 . 3 percent of observational stations is distinct . all this shows that calculational methods of zndx is more reason for studing the flood or drought of northwest chine . ( 2 ) index _ z and index _ k ca n ' t objectively remark extent of drought and flood event . both ca n ' t distinguish the difference of some years which have the same precipitation and have different temperature , awc 西北地区10个代表站三种指数值的对比表明, z指数与k指数仅反映西北地区同期的降水,而zndx指数不仅反映了同期降水状况,且与同期气温及前期气候湿润度有关。 ( 2 )通过z 、 k与zndx指数对西北地区旱涝等级的对比研究表明, z指数与k指数对西北地区旱涝等级的确定不具有客观性。 |
| 8. | Using the summer rainfall data from twenty - six observatories in shandong province from 1961 to 2001 , the subtropical high index data from 1961 to 2002 and the monthly mean reanalysis data of wind , moisture , height and olr of ncep / ncar from 1958 to 1998 , the characteristics of abnormal circulation in the northern hemisphere , the abnormal strength and location of subtropical high , the abnormal strength of monsoon and water vapor transport over the areas of east asian were studied 利用山东26个代表站1961 2001年夏季降水、 1961 2001年副高特征指数以及1958 1998年ncep ncar再分析月平均风场、高度场、比湿、 olr等资料,对山东夏季发生旱涝的北半球大气环流、副热带高压、东亚夏季风以及季风区水汽输送等异常特征进行了合成对比分析。对山东夏季旱涝形成的原因,从季风区水汽输送和出现降水异常的物理机制等方面进行了较深入的研究。 |
| 9. | The integrative chilling damage index successions of 22 representative stations for 44 years were calculated . let those successions consist of a matrix . do eof to the matrix and get two meaningful eigenvector fields , and therefore two main patterns about the spatial distribution of winter chilling damage in guangdong was found : the whole distribution pattern and the south - north distribution pattern 计算了22个代表站44年的综合寒害指数序列,构成一个综合寒害指数序列的时变矩阵,对该矩阵进行自然正交分解,获得了2个有意义的特征向量场,由此发现广东冬季寒害的地域分布主要有2种型式:整体分布型和南北分布型。 |
| 10. | By analyzing a series of precipitation data from 6 meteorological stations and gauging stations during the period from the year they had been established to 2003 , this paper gave the characteristic values of precipitation and their change regularity within a year and inter years , and studied the change trend of precipitation in i1i region 摘要根据伊犁地区6个代表站上世纪50 、 60年代至2003年的实测降水资料,分析了伊犁地区降水量的地区分布、变化特征及其多年来的变化趋势。 |
