Vorticity : 0.01 Wind : 0,5 minimum for the storms move or not if you want Global drying : 0 Global Heating : between -0,0003 and -0,0001 for progressive cooling ( Possibly use even less to cool faster, but not too much either.) Start Height : Depends on what you want to do : For temperatures close to 0°C, prefer very low heights 200m max. Sun intensity: 2 Green house gases : 0,01 Water wapor greenhouse : 0,01 Lake temp : 40°C Lake évaporation : 0,0004 Land evaporation : 0 Evaporation heat : over 3 Melting heat : between 1 and 2.5 For precipitation, it all depends on whether you have very snowy cells or not.For this simulation setting was : Precipitation Threshold -°C : 0,1 Spawn Rate : 0,0003 Snow density : 0,9 Growth Rate -30°C : 0,002 to 0,003 Snowstorms will form at sea. But snow will still fall on land
