Northeast China Is Not Immune to Typhoons: Why Liaoning Is So Frequently Affected
Despite its high latitude, Liaoning faces a significant typhoon threat from July to September each year. When typhoons form over the western North Pacific and move northwestward, they generally affect Liaoning through two pathways: first, by crossing the Yellow Sea and Bohai Sea before making landfall on the Liaodong Peninsula; and second, by making landfall in places such as Shandong or Hebei and then continuing northward as a remnant circulation. A particularly important factor is that orographic uplift in the mountainous areas of eastern Liaoning can substantially amplify rainfall. More importantly, when the typhoon's remnant moisture encounters cold air moving south from the north, a “1+1>2” amplification effect often occurs, producing extreme rainfall beyond normal expectations. Therefore, disaster preparedness should focus not only on wind but also on the risk of rainstorms caused by the interaction of typhoons and cold air.
Review of Notable Historical Cases
Looking back at typhoons that have significantly affected Liaoning in recent years, their destructive impacts often arose from the combined effects of wind and rain or from unusual tracks:
- Typhoon BAVI (2020): One of the more intense typhoons in recent years to make landfall directly in Liaoning, BAVI brought widespread violent winds and heavy rain in late August, causing considerable damage to coastal infrastructure and agriculture.
- Typhoon LEKIMA (2019): Although it made landfall mainly in Shandong, its vast circulation system moved northward and penetrated deep into Liaoning, bringing prolonged heavy rainfall to many areas and triggering urban flooding and hazards in mountainous regions.
- Typhoon LIONROCK (2016): Its track was extremely unusual, turning northwestward from near the Sea of Japan and entering Northeast China. It brought strong winds and heavy rain to Liaoning, highlighting the complexity of track forecasting.
- Typhoon DAMREY (2012): After making landfall in Jiangsu, it moved northward, causing torrential rain in southeastern Liaoning and placing several small and medium-sized rivers under flood alert.
These cases show that even when a typhoon has weakened by the time it makes landfall, the moisture and energy it carries can still cause severe disasters.
Main Risks and a Guide to Targeted Preparedness
In light of Liaoning's geographic characteristics, typhoons primarily pose four types of risk: urban flooding (drainage standards in some plain cities are lower than those in southern China, leaving low-lying road sections prone to waterlogging), geological hazards in mountainous areas (the Liaodong mountains require close vigilance for debris flows and landslides), coastal storm surges (Dalian, Yingkou, Dandong, and other areas must guard against strong winds at sea and seawater intrusion), and agricultural losses (during the critical growing periods for corn and rice, crops are vulnerable to lodging and waterlogging).
Public action recommendations:
- Monitor warning levels: The China Meteorological Administration classifies typhoon and rainstorm warnings into four levels—blue, yellow, orange, and red—with red being the highest. Pay close attention to the latest warnings issued by local meteorological observatories.
- Prepare for emergencies: Households should stock emergency supplies in advance, including flashlights, drinking water, common medicines, and power banks. Residents of low-lying areas or mountainous regions must familiarize themselves in advance with evacuation routes and the locations of the nearest temporary shelters.
- Follow official guidance: For the specific standards governing school closures, work stoppages, business closures, and evacuations, follow the latest notices issued by local governments and emergency management departments.
- Protect specific groups: People working at sea must return to port and seek shelter promptly; tourists should avoid visiting coastal scenic areas or mountainous regions while typhoons are affecting the area; and farmers should reinforce greenhouses and sheds and clear drainage channels in their fields in advance.
