对蒙古 Hovsgol 盆地地区的一组长期（1963-2002）每日最高和最低温度以及降水数据进行了分析。考察了 6 个极端气温指数和 8 个极端降水指数。结果表明，正如研究期间确定的变暖趋势所示，蒙古北部的气候条件正在发生变化。该地区每年的炎热白天和温暖夜晚的数量显着增加。与这些变化相关的是每年寒冷白天和寒冷夜晚数量的减少。蒙古北部地区降水日数略有增加，但年降水总量没有明显增加。平均而言，最大连续干旱天数没有显着减少，潮湿天数没有显着增加。 5日降水总量略有增加。版权所有 (C) 2006 英国皇家气象学会。
A long-term (1963-2002) set of daily maximum and minimum temperature and precipitation data are analyzed for the Hovsgol Basin area, Mongolia. Six indices of extreme temperature and eight indices of extreme precipitation are examined. Results suggest that climate conditions over northern Mongolia are changing as indicated by a warming trend identified during the study period. Significant increases are detected in the annual number of hot days and warm nights in this region. Associated with these changes are concomitant decreases in the annual number of cold days and cold nights. The number of days with precipitation has increased slightly while the annual total precipitation has not significantly increased in northern Mongolia. On an average, there was no significant decrease in the maximum number of consecutive dry days or increase in the wet days. The 5-day precipitation total showed a small increase.
