I've banished Winter, saith the Spring, Awake! arise, ye flowers!
Brisk breezes blow, Bright sunshine glow, And rouse the young Year's powers. From The Ministry of the Beautiful by Henry James Slack (1818-1896)
As a soft, warm breeze replaces the icy blasts of winter the smell of rich damp earth warmed by the sun fills the air. In Hertfordshire (UK) a spring morning, warm and damp and good for sowing seed is called a Hazeling.
Young tender buds appear on trees that yesterday seemed barren. Tiny crocuses lift their colourful heads to the sun. The days are getting longer and longer, and trees blossom in time for summer.
