| Thunderstorm dangers include fierce up and down winds, called updrafts and downdrafts. |
| Huge, black vultures soar over canyon, desert and forest, circling nimbly on updrafts. |
| This probably allows them to take advantage of weather patterns, like thermal updrafts and winds that speed their flight. |
| This would be placed in the path of a tornado, and would relay back wind speeds, location of downdrafts and updrafts, number of vortices, etc. |
| In some cases, intense updrafts prevent the rain-cooled air from forming the downdraft. |
| Downdrafts, updrafts, backwinds, and eddies are subtle, less easily observed factors that affect the scent trail. |
