Region Codes

Regions are classified using a code consisting of four categories: Temperature and Precipitation, Altitude, Continentality and Drainage.

Seasonal Weather

The first two blocks represent Winter and Summer. Each contains two digits: the first for Temperature and the second for Precipitation. Both are measured on a scale of 1 to 5.

Altitude

The final segment denotes the general elevation of the region:

• HL (Highlands): Peaks, ridges, and steep inclines.
• ML (Midlands): Rolling hills and plateaued steps.
• LL (Lowlands): Plains, basins, and valley floors.

Continentality

This indicates how the local climate is regulated by large bodies of water:

• CS (Coastal): Mild temperature swings and higher humidity.
• CT (Continental): Sharp temperature changes between day and night or season to season.

Drainage

Drainage determines how the ground handles water:

• GD (Good Drainage): Releases water faster than it accumulates: firm soil, few marshes, and quick runoff after rain.
• PD (Poor Drainage): Accumulates water faster than it releases: prone to bogs, standing water, and muddy trails.

Example

If you encounter the code 24 41 LL CS GD, it means that the region has cold and wet winters, hot and dry summers, is near sea-level in elevation, coastal, and has good soil drainage.
