摘要
阿里地区位于我国西南边陲,平均海拔约4500 m,因高寒缺氧、自然环境恶劣,气象站点数量稀少、设置分散(地域面积辽阔)、设备故障频发,导致气象数据缺失严重。依托“阿里原初引力波探测计划”(AliCPT)搭建的设备,利用趋势系数法、Mann-Kendall非参数检验、R/S分析等方法对阿里地区气温突变情况及变化趋势进行初步研究,结果显示:阿里地区全年约3/4的时间日均气温低于0℃,气温与海拔高度呈负相关性;2018年12月中旬至2019年4月气温整体呈下降趋势,且以2018年11月18日为起点发生突变,突变前后温差较大,突变后温度偏低、波动剧烈,难免影响探测器正常工作状态及信号输出;就R/S分析结果看,阿里地区气温变化趋势具有正持续性特征,说明未来气温变化的趋势与现在相同。本研究可以为当地居民、科技工作者有序的生产生活、科研活动提供有价值的参考。
Ali Region is located in the southwest border of China,with an average altitude of 4500 meters.Due to the high temperature and lack of oxygen,the natural environment is poor,the number of meteorological stations is scarce,the settings are scattered(the area is vast),and equipment failures occur frequently,resulting in serious lack of meteorological data.This paper mainly relies on the equipment set up by AliCPT,and uses the trend coefficient method,Mann Kendall non-parametric test,R/S analysis and other methods to conduct a preliminary study on the temperature mutation and the temperature change trend in Ali Region.The current results show that:the annual average temperature in Ali Region is below 0℃for about three quarters of the time,the temperature is negatively correlated with the altitude;The temperature is generally in a downward trend from mid-December 2018 to April 2019,and there is a sudden change starting from November 18,2018.The temperature difference before and after the sudden change is large,and the temperature after the sudden change is low and fluctuates violently,which is difficult to avoid affecting the normal working state and signal output of the detector arranged there;According to the R/S analysis results,the temperature change trend in the Ali area has a positive and continuous characteristic,which shows that the trend of temperature change in the future is the same as that in the present.It is believed that this result will provide valuable reference for the orderly production and life and scientific research activities of local residents and scientific and technological workers.
