Weather is climate here and now, and climate is weather over the long term. Climate is the large scale process of movement of air and water, and changes in the properties of air and water, on and near the surface of the Earth, the atmosphere, oceans, and ice fields respond to the imbalance of heat -- with more of it near the equator and less of it at the poles -- as the world literally turns. Weather is the local, temporal, and personally observable sign of that climate system. Climate is meaning and weather is the semiotic process by which we understand that meaning.
OK, perhaps I've gone…
