Climate - Köppen<br />

Climate refers to the statistical properties of the atmosphere<br />

and is concerned with the long-term behavior,<br />

or expected (typical) conditions.<br />

The most widely used climatic classification scheme is<br />

the Köppen system based on world distribution<br />

of natural vegetation boundaries and the<br />

combinations of monthly mean temperature<br />

and precipitation associated with those boundaries.
