For example, when there are large changes in wind speed at different altitudes (also known as «vertical wind shear») above an area of the ocean, those conditions can interfere
with hurricane formation.
Not exact matches
El Niño conditions can also curb the
formation of powerful storms, and
with no El Niño in the picture in 2017 — and
with warmer - than - average ocean waters — last year's Atlantic
hurricane season was unusually active.
For years, perhaps decades, Gray has been ascribing all sorts of climate changes and
hurricane cycles to fluctuations in the Thermohaline Circulation (THC), an overturning circulation in the Atlantic ocean associated
with formation of deep water in the North Atlantic.
Higher resolution models tended to get more
hurricane formation (perhaps unsurprisingly),
with quarter - degree models parameterized using observed SSTs generally capturing historical
hurricane formation rates fairly accurately.
According to Gerry Bell, Ph.D., NOAA's lead seasonal
hurricane forecaster, the major climate factors expected to influence this year's activity are the ongoing multi-decadal signal, which produces wind and atmospheric pressure patterns favorable for
hurricane formation, along
with ongoing warmer - than - normal sea surface temperatures.
Would another consequence of the AMOC collapse be the
formation of an Atlantic tropical warm pool comparable
with that in the western Pacific that is the source of the world's highest
hurricane frequency?
That's because even as warmer oceans provide jet fuel for
hurricanes, changes in atmospheric wind patterns can still interfere
with their
formation by preventing storms from forming or, literally, tearing them apart.
Re # 205 My initial concerns were about the path functions for
hurricanes and not for the theoretical mechanisms of
hurricane formation nor for the predicted relations of
hurricane intensity
with rising sst's etc..
