  1. 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

    旬降水量空間型時間系數間存在顯莢的統計相關，將時問系數間的1相關和互相關作為中長則天氣預報的一干！
  2. 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

    本文首先利用中國東部1990 - 2000年旬平均土壤濕度、降水和氣溫觀測資料，通過對0 - 50cm層次土壤濕度進行旋轉主分量分析（ reof ） ，重點分析了淮河流域土壤濕度的時空分佈特徵，並初步研究了與前期、同期和後期不同時段降水與氣溫的關系。
  3. Mean dekad temperature humidity ten - days average temperature humidity

    一旬逐日平均溫濕度的平均值
  4. 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

    在旬體感溫度分析的基礎上，本文選擇了不同緯度和經度的12代表性站點分析了日體感溫度的年變化規律和不同類型的體感溫度隨地理位置的變化情況，試圖從氣候角度解釋人體舒適度日變化規律的原因。
  5. 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

    與全國平均年變程相比，區域冬、春季降水偏多， 7 - 8月份降水相對偏少；區域a和b在9 、 10月份降水顯著偏多；區域11月至次年3月降水明顯偏少， 7 、 8月份降水相對偏多；區域5 - 6月份降水偏少；區域6月中旬到7月上旬降水顯著偏多，體現了長江中下游的梅雨特徵；區域a和b在11月份的降水相對偏多。
  6. The empirical orthogonal function ( eof ) is employed to analyze dekad rainfall in china in recent 44 years

    採用eof方法，將我國近44年的旬降水量進行分解。
  7. This paper is concerned with the characteristics of dekad precipitation in china based on dekad rainfall data of 188 stations from 1955 to 1998

    本文利用我國188個測站1955 - 1998年的逐旬降水資料，對我國的旬降水特徵進行研究。
  8. 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

    同時利用全國198站多年平均氣象資料計算分析了全國旬體感溫度的分佈特徵，以此為基礎進行了全國人體舒適度的區劃，並利用地理信息系統做出旬區劃圖。
  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

    長江流域旱澇年， 6 - 7月中旬來源於南海、華南地區的南邊界水汽輸入是主要影響因子， 7月下旬一8月北邊界的水汽輸出是主要影響因子。長江流域旱（澇）年夏季風水汽輸送的北界偏北（南） ，副高南側的東南風水汽輸送偏北（南） 。
