- ↑ "Sina Visitor System" 【气温】今天海南站点占据了高温榜前十中的九个席位，澄迈40.2℃，成为今年我国首个上40℃的国家气象站。包括澄迈在内，今天海南有7个站点打破3月下旬最高气温纪录，其中有4站打破3月最高气温，比如琼山38.6℃、定安38.5℃、海就38.4℃、琼海36.3℃。琼海也是首次在3月出现高温（但不是最早的高温，1979年2月24日有过35℃，为最早高温日）。明天会有冷空气南下，海南的高温强度会缩减。但之后随着冷空气离开，以及4月5日以后副热带高压加强北抬，海南的高温有所发展增多。另外未来北方冷空气活跃，重点影响东北地区。明天东北多地将有4-10℃降温，黑龙江北部降幅超10℃。4月2日气温短暂回升，4月3日以后，冷空气+频繁的雨雪，使得今年清明假期，东北气温低于常年同期，哈尔滨最高气温只有4℃上下。另外未来西北地区在暖脊影响下，气温波动上升。而且到了下周，暖气团东移，长江流域降水也减少以后，我国多地气温可能创今年以来新高。乌鲁木齐报4月2日20℃，将是今年首次上20℃，4月5日还会升至24℃；银川报4月6日最高25℃，可能是今年首次上25℃；西安报4月5日最高30℃，长沙报4月7日31℃，可能是今年首次上30℃。杭州南京报4月7日28℃、合肥报4月7日29℃，也会创新高。 (in Simplified Chinese). weatherman_信欣 on Weibo.
