Weather in Eylau

[wildb]

I saw a question about blizzards in Eylau on forum that I am not a member.  Their effect is found in the weather section of the user manual and the parameter data for the scenario.

Page 47 of the user manual:

Conditions: Normal, Snow, and Frozen. Under Frozen conditions, streams and rivers are frozen and can be crossed as though they were clear terrain. Ground Conditions are established by the scenario designer on a per-scenario basis and do not change throughout the playing of a scenario.

Weather can vary though a scenario and change at certain times specified in the Parameter Data. Each Weather state has a descriptive name associated with it such as Mud, Soft, Foggy, etc. Each Weather state has several parameters associated with it that affects the normal parameter data such as:

• Visibility – the maximum visibility associated with the weather, where 0 signifies no change.
• Movement – a percentage value that modifies the normal movement costs.
• Attacker Modifier – a percentage modifier, usually negative, that modifies the normal value of attackers in melees.
• Artillery Modifier – a percentage modifier that affects non-indirect Artillery fire at ranges of at least 5 hexes.
• Fire Modifier – a percentage modifier that affects non-Artillery fire.
• Each can have a flag associated with it signifying that Cavalry Charges are not possible under this weather condition.
