Until terminal velocity is reached of course, although wind speeds in the impact zone could also add to that.
- cs702 3y agoYes. That doesn't make it any less scary, though -- ice balls are pretty aerodynamic!
- dredmorbius 3y agoStorm cells can experience tremendous downdrafts, such that falling objects (rain, hail, small children, etc.) can see higher-than-gravitational acceleration. This is especially the case in a downburst event, where cold air suddenly collapses down through the cloud column. Which might itself be associated with / a trigger for hail formation. These downdrafts (as well as the resulting horizontal outflows of air near ground-level) have caused a number of aircraft accidents, a combination of both trying to fly through a descending air column and the sudden changes in registered airspeed as the craft first fights a strong headwind (increasing lift), then experiences a strong tailwind (decreasing it), and even causing the aircraft to stall from insufficient airspeed.
