| 摘 要： | 利用1956~2004年南阳市麦播期气象资料,分析了南阳麦播期降水量变化规律及旱、涝环流特点,结果表明:20世纪90年代以来,降水量年际变率大,麦播期降水量旱、涝问题十分突出;从1996年起,南阳市降水气候特点呈连续干旱和持续雨涝的特点。大的环流形势直接影响麦播期降水量。

| Abstract: | By using the wheat seedtime Meteorological Data from 1956 to 2004,the variational rule of wheat seedtime precipitation and circulation characters of Nanyang are analyzed.The results show that the interannual variability of the precipitation is great and the problem of the drought and flood is very remarkable since 1990;Since 1996,the characters of precipitation assume continuous drought and flood.Large circulation pattern affects the precipitation directly in this period. |
