漳平市高温变化规律研究

The Law of High Temperature Variation in Zhangping City

以漳平市国家级台站1958—2014年逐日最高气温为基础,用时间序列分析方法和Morlet小波功率谱分析方法研究漳平市高温时间分布规律。结果表明:1958—2014年温度≥35℃和37℃的年高温日数无显著变化趋势,温度≥35℃和≥37℃高温主要均出现在7月和8月。由Morlet小波功率谱分析方法得知:1958—2014年温度≥35℃年高温日数存在显著的准3a尺度周期;1958—2014年温度≥37℃年高温日数存在显著的准2~4a尺度周期。

Based on the daily maximum temperature from 1958 to 2014 of Zhangping national station, the time series analysis method and Morlet wavelet power spectrum analysis method were used to study the time distribution of Zhangping high temperature. The results showed that there was no significant change trend of annual high temperature days that ≥35℃ and ≥37℃ from 1958-2014, and the high temperature ≥35 ℃ and ≥37 ℃ mainly occurred in July and August. The analysis by the Morlet wavelet power spectrum method showed that the annual high temperature days that≥35℃ from 1958-2014 was significant quasi 3 a scale cycle, and the annual high temperature days that ≥37℃ from1958-2014 was significant quasi 2-4 a scale cycle.
