摘  要:
利用1961~2009年(5月15日~6月10日)滨州市7个台站逐日最高气温、14:00相对湿度、14:00风速及1980~2009年逐年小麦千粒重资料,采用周期方差外推法、回归分析等统计方法,对滨州市49年来干热风空间分布、年际变化和周期等特征进行分析;同时还就不同类型干热风对小麦千粒重的影响进行了初步分析。结果表明:干热风日数、干热风天气过程等级和干热风年型等级的年平均发生日数自北向南逐渐增加;年代际变化规律:20世纪60年代出现次数平均值最大,70、80年代有下降趋势,90年代发生次数最低,2000~2009年出现次数比90年代略有上升;干热风日数存在6、16年左右的周期;小麦千粒重与重干热风天气过程出现次数具有负相关关系。

摘  要:
The daily maximum temperature,14:00 relative humidity,14:00 wind speed and 1 000-grain weight of wheat data from 1980 to 2009 of 7 stations in Binzhou City during 1961-2009 (May 15th-June 10th) were used,using the statistical method of extrapolation method using cycle variance,regression analysis and so on,the spatial distribution,annual variation and cycle characteristics of dry-hot wind for 49a in Binzhou City were analyzed; Also the different types of dry-hot wind effects on wheat 1 000-grain weight were analyzed. The analysis showed that:the average annual number of days about dry-hot wind days,the grades of dry-hot wind weather processes and the grades of dry-hot wind year type occurred a gradual increase from north to south; The law of annual variation:the average number of occurrences in 1960s is the largest,the number showed downtrend in 1970s and 1980s,the number of occurrences in 1990s is the minimum,the number of occurrences for 2000s there is a slight increase over 1990s; The days of dry-hot wind there is a cycle about 6a and 16a; there is a negative correlation between wheat 1 000-grain weight and the number of occurrences about heavy weather in the process of dry-hot wind.
