| In some cases, intense updrafts prevent the rain-cooled air from forming the downdraft. |
|
| Condors hunt prey mostly by sight, soaring on thermal updrafts and wind currents until they spot a potential meal. |
|
| This probably allows them to take advantage of weather patterns, like thermal updrafts and winds that speed their flight. |
|
| Downdrafts, updrafts, backwinds, and eddies are subtle, less easily observed factors that affect the scent trail. |
|
| 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. |
|
| Warm, humid conditions are very favorable for thunderstorm development as strong updrafts feed warm, moist air into thunderstorms. |
|
| It felt like a little turbulence from thermal updrafts, a common occurrence when flying at 1,000 Feet in this area, so I wasn't worried. |
|
| 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. |
|
| Hailstones are formed by winds known as updrafts that blow upward in thunderstorms. |
|
| It shows the development of updrafts, blue thermals or cumulus clouds and significant weather phenomena as thunderstorms. |
|
| At maturity, the cell contains both updrafts and downdrafts in close proximity. |
|
| 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. |
|
| They are using updrafts to go higher without beating their wings. |
|
| Layer clouds tend to have weak updrafts and are generally composed of small droplets. |
|
| What sets it in motion are updrafts and downdrafts in the atmosphere that cause the base of the thunder cloud to rotate. |
|
| Winds were strong from the east-south-east and would have caused updrafts in the valley on the lee side of the east ridge. |
|
| These paired updrafts and downdrafts can even create a lake breeze circulation over larger bodies of water. |
|
| These paired updrafts and downdrafts can be strong enough to initiate lake-breeze circulations which are common in the Interlake region. |
|
| Heat released as the droplets freeze boosts updrafts, which pull more moist air into the cloud. |
|
|
|
| These updrafts can give turbulence with a southeast approach to the runway. |
|
| In cumulonimbus clouds during conditions where graupels are repeatedly wetted and then injected back toward high altitudes by strong updrafts, very large graupels called hail result. |
|
| The motion of a thunderstorm across the land is determined primarily by the interactions of its updrafts and downdrafts with steering winds in the middle layers of the atmosphere in which the storm develops. |
|
| Clouds with strong vertical updrafts generally have a higher liquid water content as the updrafts prevent even the large drops from precipitating. |
|
| The record altitude set by birds of prey while soaring effortlessly in thermal updrafts is typically considered to be the biosphere's upper limit. |
|
| Thermal updrafts are common over the land due to surface heating, and their effects can be particularly turbulent along boundaries where they are juxtaposed with downdrafts generated over large bodies of cool water. |
|
| Loss of visual references, strong updrafts, moderate to severe turbulence and possible wind shear likely contributed to the onset of the aerodynamic stall. |
|
| Static builds up between the cool, dry, positively charged downdrafts and the warm, moist, negatively charged updrafts, triggering an electrical discharge in the form of lightning. |
|
| This spiralling and gliding, carried out when the cranes encounter suitable thermal updrafts, is energy efficient and allows the cranes to fly nonstop for incredible distances. |
|
| Strong alpine winds are often problematic for smaller birds, however raptors including the Peregrine Falcon use the updrafts along the cliff edges to stay aloft and dive down on their prey. |
|
| Such drops are formed in strong updrafts that can hold them aloft longer. |
|
| While updrafts and downdrafts are associated with downbursts at the surface, the boundary condition precluded a significant upward wind component at the level of the runway. |
|
| Strong updrafts, downdrafts and eddies develop as the air flows over hills and down valleys. |
|
| In the spring, the snow melts off plowed fields first and the differences in surface heating, due to abrupt variations of albedo, accentuate the updrafts and downdrafts. |
|
| They are also favoured sites for early day convective initiation as updrafts can be induced or enhanced by differential heating, orographic lift, and surface convergence. |
|
| The exceptions are clouds with very strong vertical updrafts, such as towering cumulus or cumulonimbus, where liquid water droplets can be carried to great heights before freezing. |
|
| Hail is formed when updrafts in thunderclouds carry raindrops upward into extremely cold areas of the atmosphere, where they freeze and merge into lumps of ice. |
|
| You'll have to be super quiet to sneak up on a gray fox or a mule deer, but they're here, as are red-tailed hawks that soar on updrafts off the canyon walls. |
