6․25전쟁시 날씨와 전투사례와의 연계성 연구 262 군사연구 제130집 (Abstract) A Study on the Relationship between the Weather and Battles during the Korean War - Ban Ki Song - Military forces, weapons, strategies, tactics, and generalships are the factors that decide the outcome of wars and they apply to not only ancient wars but also modern warfare. However, weather has always been one of the most important factors. The 6․25(Korean War) which was provoked by North Korea 60 years ago was significantly affected by weather in many battles. Korea has very unique weather conditions. It has a rainy season called Jang-ma and 70% of the country is mountainous.

These explain why it was the weather that decided the outcome of Korean War. This report is intended to consider how to deal with weather in the future wars examining the weather factors which determined victory or defeat in the battles of Korean War. In this report, the effect of weather factors by which the outcomes of the 7 battles were decided will be analyzed for the future wars. There are several weather factors classified in this report such as precipitation and poor visibility(Battle of Miari and Battle of Punch Bowl), hot weather(Operation Kean), tides and typhoons(Battle of Incheon), the cold(Battle of Chosin Reservoir and Battle of Nambugun), and abnormal changes of weather(Operation Kean).

Therefore, if you make good use of weather information, you can manage military forces cost-effectively and conduct military training efficiently in peace time. You can also secure victory by using weather information during the war. As state-of-the-art weaponry improves, it is important that we maximize efficiency of advanced equipment and change our
