[目的]研究近54 a内蒙古自治区西部沙尘暴天气发生频次的变化特征,为该区沙尘暴天气的科学预测和防治提供理论依据。[方法]采用线性回归、5 a滑动平均、小波分析、滑动t检验、Mann-Kendall检验方法分析内蒙古自治区西部24个气象站点沙尘暴日数的变化趋势、周期性、突变性等特征。[结果]①近54 a来沙尘暴天气发生频次可分为高频期(1960-1975年)、快速减少期(1976-1992年)和低频期(1993-2013年)。沙尘暴发生的频次分别为17,9和4 d/a;发生频次的周期性存在31,22,13 a三个长周期和5,8,1.5 a三个短周期的波动变化。②1986年前后沙尘暴发生频次出现了明显的突变现象,1976-1986年的线性递减率为0.76 d/a,1987-1992年的线性递减率为1.4 d/a。[结论]近54 a内蒙古自治区西部沙尘暴日数变化呈波动下降趋势,且存在明显的周期性和突变性特征。
[Objective] The variation characteristics of sandstorm weather frequency in Western Inner Mongolia Autonomous Region in the recent 54 years were studied in order to provide theoretical basis for its scientific prediction and prevention and treatment.[Methods] Through the methods of linear regression
5-year sliding average
wavelet analysis
moving t test and Mann-Kendall
the changing trend
periodicity and mutagenicity of sandstorm day number of 24 meteorological stations in Western Inner Mongolia Autonomous Region were analyzed.[Results] ① In the recent 54 years
the frequency of sandstorm weather could be divided into high frequency period(1960-1975)
rapid attenuation period(1976-1992) and low frequency period(1993-2013). The frequency of dust occurrence was 17
9
4 days per year
there were 31
22
13 years long periods and 5
8
1.5 years short cycles. ② There was an obvious mutation in the frequency of sandstorm around 1986. The linear decrement rate of 1976-1986 was 0.76 day per years
that of 1987-1992 was 1.4 days per years.[Conclusion] In the recent 54 years
the change of sandstorm day number in Western Inner Mongolia Autonomous Region showed a fluctuating trend
and there were obvious cyclical and mutagenic characteristics.
