What are the different types of boundary conditions that affect climate?

Boundary conditions include the surface properties (sea surface temperature, vegetation, ice coverage, soil type, continental structure and topography) atmospheric composition (volcanic and anthropogenic emissions) as well as astronomical parameters (orbital changes and solar output).

Is Weather Channel or AccuWeather more accurate?

The Weather Channel and Weather Underground are again at the top of the stack nationwide for forecasting high temperatures, but AccuWeather far surpasses all rivals in its ability to predict low temperatures to within three degrees.

How can we predict the unknown weather?
