For exampleSouthern 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.
