For example Southern storm tracks typically are associated lower snow to liquid ratios than clipper type systems
1) Northern storm tracks that favor snow crystal growth by deposition favor high snow-water ratios.
2) When ice crystals grow by riming or crystals colliding with supercooled droplets, the snow-water ratios are lower.
3) Southern storm tracks and tracks that tap moisture and warm air from oceans rarely have snow to water ratios that are greater than 10-1 except well west of the storm track. Look for low ratios where precipitation becomes mixed with sleet.
