摘要

2023 年,中国气候温暖干燥。年地表气温达到新高 10.71°C,为 1961 年以来最热的秋季和第二热的夏季。同时,年降水量为 615.0 毫米,为 2012 年以来第二少。冬季至夏季降水量较常年偏少,但秋季降水量较常年偏多。与常年情况一致,5 月至 9 月汛期降水量也是 2012 年以来第二少,比常年偏少 4.3%,中部和东部地区异常,中部偏多,北部和南部偏少。相反,"华西秋雨 "带来的降水却比常年同期偏多,且开始时间偏早,结束时间偏晚。虽然 2023 年全年降水偏少,但中国遭受了严重的强降水和洪涝灾害。特别是 7 月底至 8 月初,台风 "杜苏芮 "引发的罕见特大暴雨袭击京津冀,导致华北地区旱涝急转。与此形成鲜明对比的是,西南地区从去年秋季到今年春季经历了持续干旱。初夏,华北和黄淮地区经历了 1961 年以来最强的高温过程。不过,影响中国的冷空气过程比常年偏多,其中最严重的一次出现在 1 月中旬。摘要2023年, 我国气候暖干特征明显, 全国平均气温10.71°C, 为1951年以来最暖; 全国平均降水量615.0毫米, 较常年偏少3.9%, 为2012年以来第二少。汛期(5-9月),全国平均降水量为2012年以来第二少, 中东部降水总体呈 "中间多南北少 "的分布。2023年, 我国区域性气象干旱多发, 西南地区遭遇冬春连旱; 春季北方沙尘天气过程偏多; 夏季前期, 华北和黄淮遭受1961年以来最强高温过程; 7月底至8月初, 受台风杜苏芮影响, 京津冀地区发生历史罕见极端强降雨过程, 华北地区出现 "旱涝急转"; 华西秋雨开始早, 结束晚, 雨量多。

State of China's climate in 2023

China witnessed a warm and dry climate in 2023. The annual surface air temperature reached a new high of 10.71°C, with the hottest autumn and the second hottest summer since 1961. Meanwhile, the annual precipitation was the second lowest since 2012, at 615.0 mm. Precipitation was less than normal from winter to summer, but more in autumn. Consistent with the annual condition, precipitation in the flood season from May to September was also the second lowest since 2012, which was 4.3% less than normal, with the anomalies in the central and eastern parts of China being higher in central areas and lower in the north and south. On the contrary, the West China Autumn Rain brought much more rainfall than normal, with an earlier start and later end. Although there was less annual precipitation in 2023, China suffered seriously from heavy precipitation events and floods. In particular, from the end of July to the beginning of August, a rare, extremely strong rainstorm caused by Typhoon Dussuri hit Beijing, Tianjin, and Hebei, causing an abrupt alteration from drought to flood conditions in North China. By contrast, Southwest China experienced continuous drought from the previous autumn to current spring. In early summer, North China and the Huanghuai region experienced the strongest high-temperature process since 1961. Nevertheless, there were more cold-air processes than normal impacting China, with the most severe of the year occurring in mid-January. Unexpectedly, in spring, there were more sand and dust occurrences in northern China.
