So a simple way to think about it would be comparing various events that had light winds vs higher winds. Easier for me here on the coast as most storms have strong winds here.
But recall those events that had light winds and good snow growth. You probably remember how it looked after the snow ended with the crystalline structure visible and a fluffy pack that felt like walking on a cloud as you stepped into it. Now think of some of the events that had wind. Sure the snow was dry, but when you step into the pack, it's noticeably denser. It's not the density of heavy wet snow, but it has a little girth to it. We have that here all the time. The wind can pack down the snow by pummeling the crystalline structures. It's rare to have a fluff bomb on light winds, but it does happen.
