摘要
选取2016年至2020年阿克陶国家气象观测站与7个区域自动气象站气温和降水资料,探讨盖孜河流域气温、降水分布特征和年变化特征与阿克陶国家站气温和降水的联系。结果表明:(1)盖孜河流域上游至下游五年平均气温、最高气温、最低气温均呈线性上升趋势;(2)2016年至2020年盖孜河流域平均气温下降趋势,趋势值为1.0℃/5a~1.5℃/5a,与国家站同期气温变化一致;(3)各月气温数据分析来看,1月至8月气温上升比较缓慢,上升趋势值为3.3℃/月~4.2℃/月,8月至12月气温下降较快,下降趋势值为3.5℃/月~4.6℃/月。平均气温的峰值在7月,谷值在1月;(4)盖孜河流域年平均降水量分布特点是:上游降水量多于下游降水量,中游Y6083站年平均降水量最多,年平均降水量为145.9mm,均多于阿克陶国家站降水量。
Selecting temperature and precipitation data from the Aktau National Meteorological Observatory and seven regional automatic meteorological stations from 2016 to 2020,this study explores the distribution and annual variation characteristics of temperature and precipitation in the Gaizi River Basin and their relationship with the temperature and precipitation at the Aktau National Observatory.The results show that:(1)The average temperature,maximum temperature,and minimum temperature in the upstream and downstream of the Gaizi River Basin have all shown a linear upward trend over the past five years;(2)The average temperature in the Gaizi River Basin showed a decreasing trend from 2016 to 2020,with a trend value of 1.0℃/5a to 1.5℃/5a,which is consistent with the temperature changes at the national station during the same period;(3)According to the analysis of monthly temperature data,the temperature rise from January to August is relatively slow,with an upward trend of 3.3℃/month to 4.2℃/month.From August to December,the temperature drops rapidly,with a downward trend of 3.5℃/month to 4.6℃/month.The peak of the average temperature is in July,and the valley is in January;(4)The distribution characteristics of annual average precipitation in the Gaizi River Basin are:the upstream precipitation is greater than the downstream precipitation,and the Y6083 station in the middle reaches has the highest annual average precipitation,with an annual average precipitation of 145.9mm,which is higher than the precipitation at Aktau National Station.
