央视网消息：据中国天气网消息，受寒潮过程影响，近日我国冬季版图迅速扩张，南方多地提前入 冬，从中国天气网推出的全国入冬进程图来看，冬季前沿已抵达长江沿线附近。今天（11月26日）至12 月初，还将有三股冷空气影响我国，冬季版图还会继续扩张吗？ 展望后期，11月最后几天至12月初，我国冷空气活动频繁，11月26日至27日、11月29日至30日、12月2 日至4日，将有三股冷空气先后来袭。而冷空气活动的间歇期，气温又会快速上升。在冷暖空气的拉锯 中，冷空气并不会占据优势，我国气温总体上仍将较常年同期偏高或持平，因而季节版图不会发生太大 变化。 中国天气网提醒，未来一周，刚刚入冬的南方多地昼夜温差显著大于常年同期，白天气温偏高，夜间气 温偏低。一些城市昼夜温差甚至接近20℃，冷暖反差大，建议公众采用洋葱穿衣法，早晚时段加强保 暖，中午前后方便穿脱。（策划/宋华成 设计/陈玉洁 王惟一 数据支持/于群 审核/刘红欣 刘文静 余晓 芬） 按照《气候季节划分》规定，基于当年气温序列计算5天滑动平均气温构成滑动平均气温序列，当滑动 平均气温序列连续5天小于10℃，则以其对应的当年气温序列中第一个小于10℃的日期作为冬季起始 ...
