The precipitation frequencies is analysed according to 1956 ~ 2000 years of rainfall record series in baoding area. the features of distribution of rainfall are detailed evaluated. firstly, the distribution of monthly precipitation is not even. for instance. the annual rainfall amount is about 548mm in whole year, about 80 % of them in summer season. secondly, yearly variation of rainfall is greater. thirdly, the abundant years usually are followed by short years, but the important changes have taken place in the last decades. before 70 ' s the abundant years took the dominant position, from the 70 ' s to the middle of 80 ' s the short years took place more frequently than ever. after the later of 80 ' s, the short years hold the main position. the above knowledge is instructive for guiding the rainwater resources effective utilization
本文利用1956 2000年保定市的長系列降雨資料，對保定市降水量進行了頻率分析、年內變化分析和多年變化分析，明確了保定市降水量年內、年際間的變化情況：保定市降水量年內分配不均，汛期（ 6 - 9月）占年降水量的81 。保定市降水量年際間變化大，豐水年和枯水年交替發生， 70年代以前以豐水年段為主； 70年代到80年代前期降水量豐枯交替頻繁，總的接近於枯水年段； 80年代後期至今以枯水年段為主。這種降水分佈規律對農業生產雨水資源的高效利用具有重要的指導意義。 -

本文利用1948 - 2001全球陸地月降水資料（ prec l ） ，美國ncep ncar再分析月平均風場資料和高度場資料以及英國氣象局整編的全球逐月海溫格點資料。研究了全球、北、南半球及歐亞、非洲、澳洲、北美、南美和南極大陸6個大尺度區域12 - 2月的降水趨勢變化及旱澇氣候變化。 -
Through analysing the correlation between the annual rainfall in years ( annual rainfall > ( x. - 1s ) mm ; and annual rainfall > ( x - 1s ) mm ) with notable rainfall variation from the average and monthly precipitation, we found that, apparent correlation not only exists between the monthly rainfall in rainy season and the annual rainfall, it also exists between the monthly rainfall in some
