特别提醒想要"追雪"的市民朋友，20日夜里衢州主城区有较大概率出现纯雪，虽然总体量级不大。上一 次衢州主城区出现纯雪是2024年1月，已经时隔两年。 21日至23日低温冰冻加剧。雨雪渐止后，降温效应全面凸显，大部分地区最低气温降至-1℃~-3℃，山 区低至-4℃~-6℃，全市将出现冰冻或严重冰冻天气，直至本周末寒潮影响结束，气温才会逐步回升。 雨雪天路滑、夜间气温低易结冰，驾车请减速慢行；户外需防范大风刮落物，山区出行尽量避开陡坡路 段。同时，低温天气需注意用电用火安全，防范电力设备和供水设施冻裂，保障居家生活正常。 "窗外灰蒙蒙一片，到底是雾还是霾？"昨日清晨不少市民发出疑问。气象专家解释，雾和霾的核心区别 在于相对湿度与成分：雾是水汽凝结形成的微小水滴，相对湿度大于90%，呈乳白色且潮湿感明显；霾 则是灰尘、污染物等干微粒聚集形成，相对湿度小于80%，颜色偏混浊暗沉。监测数据显示，昨日早晨 市区相对湿度未达雾的形成标准，因此判定为霾。不过随着夜间雨雪天气到来，空气湿度将显著上升， 霾天气会逐步消散，空气质量也将改善。 本报讯 （记者 陈霞） 刚感受完20℃+的日间暖意，强寒潮已"整装待发"。记者从市气象部 ...
