AB - This study analyzed Standard Precipitation Index (SPI) at 6 stations near Chungbuk area for 1 to 12 months of duration, along with drought characteristics such as the degree of resiliency and vulnerability. There was no significant difference in the number of months with negative SPI according to the duration. However, SPI12 was associated with a large percentage of negative SPI, despite the small data size. SPI12 remained negative in Chungju, Jecheon, Yeongwol, and Cheongju branches over 12 months, which indicates a particular vulnerability to long-term drought. In particular, the 12-month average of SPI12 values was -1.0 or lower in Yeongwol and Cheongju, indicating that they were vulnerable to drought. The SPI12 for resiliency was below 0.1 in Jecheon, Yeongwol, and Cheongju, which confirms that it was the most vulnerable period in terms of returning to the normal state. The SPI12 for vulnerability was below –0.8 in Chupungyeong, Jecheon, Yeongwol and Cheongju and they were particularly vulnerable to 12 months of continuous drought.
This study confirms that the Chungbuk region is vulnerable to 12 months of droughts and so needs to develop a response strategy based on drought characteristics.
