what differentiates one from another and how can you tell if it never hits the ground?
When it comes to verga and grapple rain %26amp; snow that don't hit the ground is all grapple once verga?
If it's virga, it NEVER reaches the ground. It evaporates before reaching the ground. You can't always tell for sure that it didn't reach the ground, but if it looks like it's evaporating 8000 feet above the ground, it probably is. Or, maybe you can see it right over your head, and no raindrops are hitting the ground around you.
There's no connection, per se, between virga and grapple. The former describes the behavior of the precipitation, and the latter describes it's characteristics. Virga can be snowflakes, grapple or rain.
Bonus info!: Virga is good at creating microbursts.
