Meteorological experts are concerned about this plum rain front because its "circulation pattern
" is conducive to the development of a "mesoscale convective system." Under these conditions, severe weather is likely to strike.
The polar vortex is a circulation pattern
near the poles in a layer of upper atmosphere called the stratosphere.
Instead, gas expelled from the center interacts with infalling gas to create a dynamic circulation pattern
, similar to a water fountain in a city park.
The idea of climate change causing a major circulation pattern
in the Atlantic Ocean to collapse with catastrophic effects has been the subject of doomsday thrillers in the movies but, in climate forecasts, it mostly is regarded as an extreme longshot.
Scientists have learned that pollution originating from farther south in the Northern Hemisphere "would naturally get blown northward because that's the dominant circulation pattern
to move from lower latitudes toward the poles," explains Tim Garrett of the University of Utah, who coauthored a recent study in Geophysical Research Letters that reveals the extreme sensitivity of Arctic clouds to this pollution, and the possibility that particulate matter could trigger cloud formation in the region.
This anomalous circulation pattern
weakened water vapor transport from the SCS along the northwestern flank of the WPSH.
atmospheric conditions and the underlying circulation pattern
), the balance of which may largely vary depending on the particular meteorological situation.
That untypical circulation pattern
was what made March so warm.
The remains separated from the vortex circulation pattern
and within less than a day became a thing of the past.
All Envirosealed enclosures are designed with minimum internal obstructions and a planned air circulation pattern
to maximize self-cooling through the enclosure skin.
To ensure efficient circulation pattern
is a critical dilemma of modern urban transport management.
Predicted circulation patterns
are always qualitatively accurate, and the transitions from one circulation pattern
to another, predominantly with changes in off bottom clearance, are also accurately predicted (Fokema et al., 1994; Coy et al., 1996).
