"Thunder from the Sky..." Weather Anomaly? Climate Change? Why Does Hail Fall?

Recent Hail Damages Crops
Seasonal Factors Cause Cold Air Above,
Warm Air Below Creates 'Ice Chunks'

In early this month, it was revealed that the scale of crop damage caused by sudden hail was significant, drawing attention to the background of the hailstorm. Various analyses have emerged, including views that it is a weather anomaly or due to climate change.

The Ministry of Agriculture, Food and Rural Affairs announced that the crop damage caused by hail reported to local governments amounted to 3,089 hectares as of the 15th. By item, damage to fruit trees such as apples, peaches, plums, and pears accounted for 70% of the total, the largest share. By region, Gyeongbuk accounted for more than half of the total damaged area with 1,712 hectares.

Experts believe that seasonal factors play a major role in the recent hailstorms. Hail mainly occurs when cold air is present in the upper atmosphere and warm air is in the lower atmosphere, causing atmospheric instability.

When cold air remains in the upper layers, ice chunks form inside clouds. These chunks move between the upper and lower layers of the atmosphere due to instability, gradually becoming heavier and larger. When they reach a certain size, they fall to the ground as hail. In terms of seasons, this typically occurs in May to June and September to October.

As a result, some express concerns that if abnormal weather phenomena such as weather anomalies occur, hailstorms might increase. However, according to the Korea Meteorological Administration, it is more natural to view hail as a phenomenon caused by climate change rather than a weather anomaly. A KMA official explained, "It is better seen as climate change rather than a weather anomaly."

Meanwhile, local governments are currently conducting detailed investigations to support hail damage recovery. Based on the results of these investigations, recovery costs such as pesticide costs, seedling costs, and livelihood support funds will be provided to affected farmers. Additionally, for farmers with severe damage, support will be given for deferring repayment and reducing interest on agricultural policy loans. Local governments and the Ministry of Agriculture, Food and Rural Affairs plan to establish a damage recovery plan and provide support by the end of this month.
