昨天至今晨，京城迎来一场三月飞雪，雪后的北京一片银装素裹，树木枝条挂满了厚厚的积雪，形成今年冬天一场最美丽的雪淞。“白雪却嫌春色晚，故穿庭树做飞花”。早上起来，碧蓝的天空、纯净的白雪，再配上清新的空气，怎么看都是适合出门赏景拍摄的好时机。但是，三月的雪景难留，随着太阳升高，树上的积雪开始融化，纷纷落下。赶紧拿起相机和上班的家伙，在院子里先拍几张，之后赶往最近的紫竹院公园，留下了难得的雪淞美景。【雪淞的形成：雪花飘落时气温较高，部分雪花落到地面或树木上化成水。在降雪过程中，如果遭遇寒流，气温骤降，雪就不再融化，雪花被树枝上的水珠粘住、冻结，越积越厚，就形成了雪凇。雪淞的形成条件比较苛刻，所以并不常见。】
