"北方冬麦区大部降水接近常年或偏多，利于补充土壤水分和缓和旱情，气象条件总体利于冬小麦 产量形成。"黄卓说，长江流域油菜产区气温偏高，降水正常或偏少，有利于油菜灌浆成熟和收获晾 晒；西南地区南部油菜陆续成熟，需防范阶段性阴雨天气影响收晒，以防籽粒霉变。 需要注意的是，江淮、江汉、江南、华南东部等地温度高降雨少，部分地区可能出现农业干旱和用 水紧张；5月中下旬黄淮南部、江淮、江汉温度高降雨少，出现阶段性农业干旱和干热风天气风险较 高。 国家气候中心副主任肖潺说，目前，华南西部、西南地区东南部等地仍存在中旱及以上等级气象干 旱，广西局地特旱。 中国气象局统计显示，4月下旬南方多地频繁降水，一定程度上缓和了华南东部等地气象干旱，华 南中旱及以上等级气象干旱面积由4月19日的37万平方公里减少到4月27日的22.6万平方公里，同期特旱 面积由22.6万平方公里下降到8.7万平方公里。 新华社北京4月28日电 新闻分析：近期天气对春耕春种影响几何？ 新华社记者 刘诗平 5月，我国夏收粮油作物将进入产量形成关键期，东北地区将大面积开展春播。近期天气将对春耕 春播和作物生长带来哪些影响？ 国家气象中心副主任黄卓28日在中国 ...

每经记者 李彪 每经编辑 陈旭 全球变暖正在快速影响着地球南北极的海冰面积。 4月28日，中国气象局举行新闻发布会，发布4月全国天气气候特征、"五一"假期天气预报、5月气候趋势预测及气象服务提示等，同时还发布了2024年度 《极地气候变化年报》及《防雷减灾管理办法》。 2024年度《极地气候变化年报》显示，南极海冰范围年度最低值为197万平方公里，是史上第三低的纪录。北极海冰持续偏少，最小值为421万平方公里，与 2023年相当，位列历史第七低值。而在2024年12月，北极海冰范围还创下自1979年以来46年间该月份的最低纪录。 《每日经济新闻》记者就此在发布会上提问：过去几年，南极海冰持续处于低位，北极也创造了近半个世纪以来12月海冰范围的低值纪录，这种现象还会持 续吗？ 对此，中国气象科学研究院全球变化与极地研究所所长丁明虎表示："全球变暖是一个长期的趋势，会导致南大洋和北冰洋的海水温度也随之上升。温暖的 海水会抑制海冰的形成，同时加速海冰的融化。" 2024年，南极大陆年均气温为-31.79℃，较1991~2020年气候均值略高0.05℃。7~8月南极出现罕见的持续性暖事件，8月南极大陆大部分区域月平均 ...
