内蒙古寒潮时空变化数据集（1960-2012）

本研究依据内蒙古及周边121个气象台站1960-2013年逐日最低气温数据，以当年9月1日-次年5月31日范围内的寒潮次数定义为一个完整的寒潮统计年的寒潮发生频次，采用分段线性回归模型、Sen趋势分析和Mann-Kendall统计检验方法，得到内蒙古寒潮频次的时间（年际、季节、月份）和空间变化数据集。数据集包括：（1）内蒙古及周边121个气象台站位置数据；（2）1960-2012年内蒙古单站寒潮频次年际变化；（3）1960-2012年内蒙古单站寒潮频次春季变化；（4）1960-2012年内蒙古单站寒潮频次月份变化；（5）1960-2012年内蒙古区域寒潮频次变化；（6）1960-2012年内蒙古逐站点寒潮频次变化；（7）1960-2012年内蒙古单站寒潮频次和转折点1991年前后的寒潮频次数据；（8）内蒙古单站寒潮频次分布；（9）1960-2012年内蒙古寒潮和转折点1991年前后的寒潮变化趋势数据；（10）内蒙古寒潮变化趋势分布。数据集存储为.xlsx、shp格式，压缩后数据量为48KB。该数据集的分析研究成果发表在《地理学报》2014年69卷第7期。

This study is based on daily minimum temperature data from 121 meteorological stations in Inner Mongolia and its surrounding areas during 1960–2013. The number of cold wave events within the period from September 1st of the current year to May 31st of the following year was defined as the cold wave occurrence frequency of a complete statistical cold wave year. Using the segmented linear regression model, Sen's trend analysis, and Mann-Kendall statistical test methods, we obtained temporal (inter-annual, seasonal, monthly) and spatial variation datasets of cold wave frequency in Inner Mongolia. The dataset includes:
(1) Location data of 121 meteorological stations in Inner Mongolia and its surrounding areas;
(2) Inter-annual variations of cold wave frequency at individual meteorological stations in Inner Mongolia during 1960–2012;
(3) Spring variations of cold wave frequency at individual meteorological stations in Inner Mongolia during 1960–2012;
(4) Monthly variations of cold wave frequency at individual meteorological stations in Inner Mongolia during 1960–2012;
(5) Regional cold wave frequency variations in Inner Mongolia during 1960–2012;
(6) Cold wave frequency variations at each meteorological station in Inner Mongolia during 1960–2012;
(7) Cold wave frequency data at individual meteorological stations in Inner Mongolia during 1960–2012, as well as cold wave frequency data before and after the turning point year 1991;
(8) Spatial distribution of cold wave frequency at individual meteorological stations in Inner Mongolia;
(9) Cold wave change trend data in Inner Mongolia during 1960–2012, as well as trend data before and after the turning point year 1991;
(10) Spatial distribution of cold wave change trends in Inner Mongolia.
The dataset is stored in .xlsx and shp formats, with a compressed size of 48 KB. The analytical research results of this dataset were published in *Acta Geographica Sinica*, Vol. 69, No. 7, 2014.
