The “Garcia Method” -- Update
Garcia amended his original method to account for:
- Heavy snowfall events in which the snow:liquid equivalent ratio, in very cold and dry Arctic air, has to be taken into account. Snow:liquid equivalent ratios in these cases can be as high as 30:1.
- Heavy snowfall events in which snowfall was enhanced due to jet streaks or coupled jet streaks. In these cases thundersnow is often observed due to upright or slantwise convection. Garcia recommends a 4:1 ratio for snowfall:mixing ratio. Of course, the speed of these dynamic systems must be taken into account as well.
