Question

why do we say that weather is a complex phenomenon​

Answer 1

Answer:

It is because the weather depends on so much factors. A minor change in even one factor contributes to a vast change in the weather itself. Suppose the morning sky was sunny, with very less humidity. But in the afternoon, clouds start to get collected over sky due to evaporation, which leads to increase in humidity.
