기온 및 강수량 기록경신 발생빈도

The current observed value of the ratio of daily record high maximum air temperatures to record low minimum air temperatures averaged across the Korea is about “2.5”. This is because records that were declining uniformly earlier in the 20th century following a decay proportional to 1/n(n being the number of years since the beginning of record keeping) have been declining less slowly for record highs than record lows since the late 1980s. The results used the same approach in the ratio of daily record high maximum moving average precipitation statistics to record low minimum moving average precipitation statistics averaged across the Korea has not characteristic value but large variance.
