How to say the weather in classical Chinese?

When "weather" refers to short-term climate (such as sunny weather today), classical Chinese is called "weather".

For example, Cao Pi's Ge Yanxing: "The autumn wind is bleak and the weather is cold, and the vegetation is like frost." Du Fu's two lines "For the Road": "On March 3, the weather is sunny and beautiful, and there are many beautiful people along the Chang 'an River." ?
