                  There is no commonly used general concept for the weather in pre-Buddhist Chinese. The closest we come is perhaps qì 氣 as in ZUO 天有六氣, but consider the whole passage:

                  天有六氣, (In the same way) there are six heavenly influences,

                  降生五味, which descend and produce the five tastes,

                  發為五色, go forth in the five colours,

                  徵為五聲。 and are verified in the five notes;

                  淫生六疾。 but when they are in excess, they produce the six diseases.

                  六氣曰陰、陽、風、雨、晦、明也, Those six influences are denominated the yin, the yang, wind, rain, obscurity, and brightness.

                  分為四時, In their separation, they form the four seasons;

                  序為五節, in their order, they form the five (elementary) terms.

                  過則為菑: When any of them is in excess, there ensues calamity.

                  陰淫寒疾, An excess of the yin leads to diseases of the cold;
