摘要20世纪80年代末，整个北方半球发生了一次突然的气候体制转变（CRS），影响了海洋和内陆沃茨。在瑞士，河流和湖泊突然变暖。20世纪80年代后期CRS前后的水温逐月比较显示了变暖幅度的季节差异，冬季，春季和夏季比秋季更强。在湖泊中，增加的幅度和变化的不稳定性随着深度的增加而减少。地表温度显示出最一致的突然变暖。下湖温度也增加了，但在研究的4个湖泊中，有3个湖泊的变化是渐进的。20世纪80年代末的突然变暖大大促进了瑞士水体在过去几十年中出现的总体温度上升。
Abstract In the late 1980s, a sudden climate regime shift (CRS) occurred throughout the Northern Hemisphere that affected both marine and inland waters. In Switzerland, rivers and lakes underwent an abrupt warming. A month-by-month comparison of water temperatures before and after the late 1980s CRS shows seasonal differences in the magnitude of the warming, which was stronger in winter, spring, and summer than in autumn. In lakes, the magnitude of the increase and the abruptness of the change diminished with increasing depth. Surface temperatures showed the most consistent abrupt warming. Hypolimnetic temperatures also increased, but the change was gradual in 3 of the 4 lakes studied. The abrupt warming in the late 1980s contributed substantially to the overall increase in temperature that has occurred in water bodies in Switzerland over the last few decades.
