基于黔南州区域自动气象站资料的干旱分析
|
摘要
利用黔南州区域自动气象观测站和县级气象观测站的降水量资料,对比分析黔南州2011、2013年夏季干旱的特征。结果表明:2011年是于7月上旬—9月底的夏秋连旱,干旱程度为特旱,州的北部、中部和东部干旱严重,州的西部干旱稍轻。2013年是6月中旬开始,8月逐渐解除干旱的夏季干旱,州的北部和中部的局部地区干旱严重,中南部多数地区以轻、中旱为主。利用区域自动站资料分析干旱,比用县级气象观测站资料分析更能够清晰判断干旱的分布区域和干旱强度的层次,使干旱监测、分析更好反应出实际情况,由于观测的气象要素少,观测时间短,在干旱分析中也有不足之处,该文是区域自动气象观测资料分析的一次尝试。
Based on the precipitation data of Qiannanzhou regional meteorological observation station and county meteorological observation station,the characteristics of summer drought in Qiannan period in 2011 and 2013 were compared and analyzed. The results show that the drought is drought and drought in the north,central and eastern parts of the state in early July and the end of September. The drought in the western part of the state is slightly dry. 2013 is the beginning of mid-June,in August gradually relieved drought in the summer drought,the northern and central parts of the country serious drought,most of the central and southern regions to light,drought-based. It is better to use the data of the regional automatic station to analyze the drought,and to analyze the distribution of the drought and the level of the drought intensity more clearly than to analyze the data of the county meteorological observation station. The drought monitoring and analysis can reflect the actual situation. Because the observed meteorological factors are few,The observation time is short and there are shortcomings in the drought analysis. This paper is an attempt to analyze the regional automatic meteorological observation data.
