| 1. | Mean dekad temperature humidity ten - days average temperature humidity 一旬逐日平均温湿度的平均值 |
| 2. | The empirical orthogonal function ( eof ) is employed to analyze dekad rainfall in china in recent 44 years 采用eof方法,将我国近44年的旬降水量进行分解。 |
| 3. | This paper is concerned with the characteristics of dekad precipitation in china based on dekad rainfall data of 188 stations from 1955 to 1998 本文利用我国188个测站1955 - 1998年的逐旬降水资料,对我国的旬降水特征进行研究。 |
| 4. | There are significant statistical correlations among temporal coefficients of spatial patterns of dekad precipitation . lag correlations and cross correlations can be viewed as one clue to mid - long term weather forecast 旬降水量空间型时间系数间存在显荚的统计相关,将时问系数间的1相关和互相关作为中长则天气预报的一干! |
| 5. | The body comfort index is established . at the same time , the dekad apparent temperature distributing character of all over the country were calculated and analyzed based on many years average weather data of 198 stations 同时利用全国198站多年平均气象资料计算分析了全国旬体感温度的分布特征,以此为基础进行了全国人体舒适度的区划,并利用地理信息系统做出旬区划图。 |
| 6. | On the basis of dekad apparent temperature analysis , selected 12 representative stations on different latitude and longitude , the yearly change rule of dayly apparent temperature and different type apparent temperature - 2 - change condition with geography position are calculated and analyzed and dayly change rule of body comfort degree is attempted to discuss from climate angle 在旬体感温度分析的基础上,本文选择了不同纬度和经度的12代表性站点分析了日体感温度的年变化规律和不同类型的体感温度随地理位置的变化情况,试图从气候角度解释人体舒适度日变化规律的原因。 |
| 7. | Compared with annual variation averaged over china , rainfall in region 1 is more in winter and spring but less in july and autumn ; region ii a and ii b have more rainfall in september and october ; rainfall in region iii is less from november to march of the next year while more in july and autumn ; region iv has less rainfall in may and june ; precipitation in region vis significantly more from middle - dekad in june to first - dekad in july , which manifests the feature of meiyu in middle - lower reaches of the yangtze river ; region via and vib have more rainfall in november . the characteristic periods of time are defined which indicate the typical characteristics of rainfall in each region 与全国平均年变程相比,区域冬、春季降水偏多, 7 - 8月份降水相对偏少;区域a和b在9 、 10月份降水显著偏多;区域11月至次年3月降水明显偏少, 7 、 8月份降水相对偏多;区域5 - 6月份降水偏少;区域6月中旬到7月上旬降水显著偏多,体现了长江中下游的梅雨特征;区域a和b在11月份的降水相对偏多。 |
| 8. | With reof analyze technique , the mainly anomalous spatial features of soil humidity in the 0 - 50cm layer of huai river basin and their relations to different periods of precipitation and air temperature are specially analyzed by using the observed data including dekad averaged soil moisture , precipitation and air temperature data over the east of china from 1990 to 2000 . the results indicate that in the springtime the 30cm layer soil can be treated as a boundary 本文首先利用中国东部1990 - 2000年旬平均土壤湿度、降水和气温观测资料,通过对0 - 50cm层次土壤湿度进行旋转主分量分析( reof ) ,重点分析了淮河流域土壤湿度的时空分布特征,并初步研究了与前期、同期和后期不同时段降水与气温的关系。 |
| 9. | In the droughts or floods over the yangtze river basin , between june and the second dekad in july , the moisture transport from the southern boundary , originating from south china sea and south china , is the most important influence factor , but between the last dekad in july and august , the one flowing out from northern boundary is the most important influence factor 长江流域旱涝年, 6 - 7月中旬来源于南海、华南地区的南边界水汽输入是主要影响因子, 7月下旬一8月北边界的水汽输出是主要影响因子。长江流域旱(涝)年夏季风水汽输送的北界偏北(南) ,副高南侧的东南风水汽输送偏北(南) 。 |
