Abstract

The standardized precipitation index (SPI) has been recognized as the standard index that should be used for quantifying and reporting meteorological drought. This study presents the implementation of the two-dimensional correlation method for determining the spatial and temporal variability of drought among the SPI series. The developed method was applied on 13 stations in Central Anatolia. The results show that the presented approach is capable of quantitatively assessing the differences in drought behaviour between stations. The paper also presents heatmaps as a new way of visualizing SPI series enabling detection of dry and wet periods.

基于二维相关分析的干旱变率检测

标准化降水指数（SPI）已被公认为用于量化和报告气象干旱的标准指数。本研究介绍了确定SPI序列中干旱时空变异性的二维相关方法的实现。所开发的方法已应用于安纳托利亚中部的13个台站。结果表明，该方法能够定量评估站点之间干旱行为的差异。本文还提出了热图作为一种可视化SPI系列的新方法，可以检测干旱和潮湿时期。

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
