石河子市近63a降雨特征分析
Analysis of Precipitation Characteristics Re-cent 63 Years in Shihezi City
摘要:
本文通过对石河子市近63a年降水量季(5~9月)降水量资料分析，结果表明：石河子市年降水量呈显著增加，冷季降水对年降水量的贡献明显大于暖季降水量的贡献，暖季降水量虽也呈增加趋势，但降水量的增加主要来自大雨和暴雨的明显增加；石河子市暖季极端降水事件发生频次也显著增多，特别是20世纪80年代中期后表现明显；暖季降水有明显的日变化，降水量的高值时段为夜间，最大小时降水出现在22时，且降水强度也在此时段最大、出现频次也最多。
Abstract:
The paper analyzed annual precipitation and warm season (from May to September) precipitation recent 63 years in Shihezi City. The results showed that the annual precipitation was significantly increased; the cold season precipitation is more significant than warm season; the warm season precipitation is also increased, but the increase of precipitation mainly derived from the heavy precipitation and it increased significantly. The frequency of extreme precipitation is also significantly increased in the warm season in Shihezi, especially after the mid-1980s. The precipitation has obvious diurnal variation in warm season, the high-value period at night, the maximum hourly precipitation occured at 22 hour, the largest intensity and most frequent of precipitation is also in this period.
