What are the similarities and differences between climate and weather?

They have something in common: both are atmospheric conditions.

The difference between them is that the weather is short and changeable. (e.g. snow, rain) Climate is the average weather condition in a place, which generally does not change much. So the description of "weather" is more specific, and the description of "climate" is more general. For example, the four seasons are like spring, with high temperature and severe cold and drought all the year round.
