This hampered efforts to discuss important concepts that we can normally see in animations, such as accelerations and jet streak
digging on satellite water vapor imagery, or how convective mode is changing on radar loops.
Figure 4(a) displays a jet streak
>80 m [s.sup.-1] over the Pacific Ocean between 175[degrees]W and 155[degrees]W.
"We are on the south side of the storm which tends to have the strongest winds but we will also have a 'jet streak
' in the upper flow lined up west to east across the Pennines.
While the trough at 250 hPa propagates eastward over the 12 hours leading up to the event (not shown), the jet streak
in all five CWAs tends to build backward, appearing to strengthen or propagate westward.
In order to better evaluate the role of upper-level jet streak
dynamics in this case, 0-h RUC model forecasts were examined on a tri-hourly basis, starting at 1800 UTC 11 January 2004.
Estofex said the arrival of a cold front and jet streaks
in the atmosphere could create conditions for a rapid thunderstorms which may include severe wind gusts and flash floods.

Moore's analysis suggests that the sudden drops in barometric pressure on Mount Everest in springtime are associated with jet streaks
, which are areas of higher-than-average wind speed within the jet stream that steers storm systems through the Himalayan region each spring.
But on May 10, 1996, there were two fast-flowing air streams, called jet streaks
, moving over the mountain.
Within the jet stream are jet streaks
, smaller regions of even greater wind speeds.
But while they were on it, two fast-flowing airstreams, called jet streaks
, moved over forcing down the stratosphere, according to new analysis of weather patterns.
But on May 10, 1986, there were two streams of very fast-flowing air called jet streaks
moving over the mountain.
