| If a tilt is created in these drafts by wind shear, additional up or downdrafts can occur and this can result in extra cells being formed. |
|
| Thunderstorm dangers include fierce up and down winds, called updrafts and downdrafts. |
|
| If downdrafts become localized, they can become violent downward bursts of wind that can overpower or even destroy any aircraft. |
|
| 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. |
|
| Eventually saturation occurs and precipitation falls and downdrafts occur. |
|
| He battled huge updrafts and downdrafts to take Solo Spirit up and over a 6700-metre Andean peak in a manoeuvre so risky he opted to wear a parachute. |
|
| At the time, I was looking for software to visualize my 3-D model data of microbursts, severe downdrafts that sometimes descend from thunderstorm clouds. |
|
| Strong updrafts, downdrafts and eddies develop as the air flows over hills and down valleys. |
|
| This auto repair and collision repair company has state of the art spray booths with downdrafts. |
|
| Stormy squalls packing severe downdrafts took his Spirit of Freedom craft as low as 400ft from the sea east of New Zealand. |
|
| Large-scale downdrafts, like those over Earth's deserts, are dry because the moisture falls out in the neighboring updraft regions, Ingersoll explains. |
|
| Even such diverse and distant countries as Russia, South Africa, Brazil and Australia have been caught in the downdrafts of financial or currency volatility. |
|
| Downdrafts, updrafts, backwinds, and eddies are subtle, less easily observed factors that affect the scent trail. |
|
| Downdrafts can push a plane into the ground, regardless of the presence of a runway. |
