【摘要】：利用云南省1960—2013年逐日0cm地面溫度觀測(cè)資料,運(yùn)用Mann-Kendall趨勢(shì)和突變檢驗(yàn)法、小波分析法等分析了云南地面溫度的空間分布、變化趨勢(shì)及突變特征、周期變化及可能的影響因素。結(jié)果表明:年平均地溫、年平均最低地溫整體上呈現(xiàn)"南高北低"的分布特點(diǎn),年平均最高地溫呈現(xiàn)出"西北、東北低,中部、南部高;深切河谷高,高原面較低,高聳山地更低"的分布特點(diǎn);同時(shí),也表現(xiàn)出明顯的區(qū)域性差異;年平均地溫、年平均最高(低)地溫高值中心主要分布在元江河谷(元江站),金沙江河谷(元謀站),滇南瀾滄江及其支流河谷(景洪站、勐臘站);平均地溫、平均最高(低)地溫季節(jié)分布特點(diǎn)與年際分布大致相似。平均地溫、平均最高(低)地溫年際、季節(jié)及不同氣候帶均呈增溫趨勢(shì);年平均地溫、年平均最高(低)地溫均以冬季增溫幅度最大;年平均地溫、年平均最低地溫以高原氣候帶增溫幅度最大,年平均最高地溫以北熱帶增溫幅度最大。年平均地溫、年平均最高(低)地溫及不同氣候帶地溫均發(fā)生顯著突變;其中,年平均地溫、年平均最高(低)地溫顯著突變點(diǎn)分別為2000年、2004年、1997年;年平均地溫、年平均最高(低)和不同氣候帶地溫均以長(zhǎng)周期變化為主周期;其中,年平均地溫、年平均最高(低)地溫主周期分別為28a,26a,26a。年平均地溫、年平均最高(低)地溫與緯度和海拔呈極其顯著的負(fù)相關(guān);1960—2013年亞洲區(qū)極渦面積(強(qiáng)度),西太平洋副高西伸脊點(diǎn)指數(shù)顯著減弱,西太平洋副高面積(強(qiáng)度、脊線)、印緬槽、西藏高原、印度副高面積指數(shù)呈顯著增加可能是引起云南地溫變化的原因之一。
[Abstract]:Based on the daily 0cm ground temperature observation data from 1960 to 2013 in Yunnan Province, the spatial distribution, variation trend and abrupt change characteristics of ground temperature in Yunnan Province are analyzed by using Mann-Kendall trend and mutation test method, wavelet analysis method and so on. Periodic changes and possible influencing factors. The results show that the annual mean ground temperature and the annual mean lowest ground temperature are "south high and north low" as a whole, and the annual average highest ground temperature is "northwest, northeast low, central and southern high;" The deep valley is high, the plateau surface is lower, the towering mountain is lower ", at the same time, there are obvious regional differences. The annual mean ground temperature is the highest (low) and the high value center is mainly distributed in the Yuanjiang River Valley (Yuanjiang Station), the Jinsha River Valley (Yuanmou Station), the Lancang River and its tributaries in Southern Yunnan (Jinghong Station, Mengla Station). The seasonal distribution characteristics of mean ground temperature and average highest (low) ground temperature are approximately similar to that of interannual distribution. The mean ground temperature is the highest (low) interannual, the seasonal and different climatic zones show a trend of warming, and the annual mean ground temperature, the annual average maximum (low) ground temperature is the largest in winter. The annual mean ground temperature is the highest in the climate zone of the plateau and the largest in the north of the tropical zone. The annual mean ground temperature, the annual mean highest (low) ground temperature and the different climatic zone ground temperature all have significant mutation, among them, the annual mean ground temperature, the annual average maximum (low) ground temperature significant mutation point are 2000, 2004, 1997 respectively; The annual mean ground temperature, annual mean maximum (low) and different climatic zones are dominated by long period variation, in which the annual mean ground temperature and the annual average maximum (low) earth temperature are 28a ~ 26a ~ 26a ~ (26) a, respectively. The annual mean ground temperature, annual mean maximum (low) soil temperature was significantly negatively correlated with latitude and altitude. From 1960 to 2013, the Asian polar vortex area (intensity), the west Pacific subtropical high ridge extension point index significantly weakened, the western Pacific subtropical high area (intensity, ridge line), the Indo-Burma trough, the Tibet plateau, A significant increase in the Indian subtropical high area index may be one of the reasons for the change of ground temperature in Yunnan.
