The changes in MHW properties (Fig. 1b, e, h, k) also clearly indicate signatures of a negative PDO pattern (SST decreases in the central and eastern tropical Pacific and in the eastern extra tropical Pacific Ocean; Supplementary Fig. 2A) and of a positive AMO pattern (SST increases in the North Atlantic particularly away from the mid-latitudes; Supplementary Fig. 2B).

Similarly, if as a number of recent studies suggest, anthropogenic climate forcing leads to a greater tendency for the positive phase of the North Atlantic Oscillation (NAO)[or related «Arctic Oscillation» (AO)-RSB- pattern, we would expect increased baroclinicity and storminess over a substantial region of the mid-latitude North Atlantic ocean and neighboring western Europe..

However, the colder ocean surface reduces upward radiative, sensible and latent heat fluxes, thus causing a large (∼ 50 W m − 2) increase in energy into the North Atlantic and a substantial but smaller flux into the Southern Ocean (Fig.ocean surface reduces upward radiative, sensible and latent heat fluxes, thus causing a large (∼ 50 W m − 2) increase in energy into the North Atlantic and a substantial but smaller flux into the Southern Ocean (Fig.Ocean (Fig. 8c).

Increased high pressure due to cooler high - latitude ocean (Fig. 20) can make blocking situations more extreme, with a steeper pressure gradient between the storm's low - pressure center and the blocking high, thus driving stronger North Atlantic storms.

If this tropical warming is combined with a cooler North Atlantic Ocean from AMOC slowdown and an increase in midlatitude eddy energy (Fig. 21), we can anticipate more severe baroclinic storms.

A recent paper by Vecchi and Soden (preprint) published in the journal Geophysical Research Letters has been widely touted in the news (and some egregiously bad editorials), and the blogosphere as suggesting that increased vertical wind shear associated with tropical circulation changes may offset any tendencies for increased hurricane activity in the tropical Atlantic due to warming oceans.

«The climate patterns responsible for the expected above - normal 2007 hurricane season continue to be the ongoing multi-decadal signal (the set of oceanic and atmospheric conditions that have spawned increased Atlantic hurricane activity since 1995), warmer - than - normal sea surface temperatures in key areas of the Atlantic Ocean and Caribbean Sea, and the El Nino / La Nina cycle»

These features can be responsible for the increased frequency of tropical cyclones over the North Atlantic Ocean.»

Here's a quote: «Given the projected 21st century rise in greenhouse gas concentrations and increased fresh water input to the high latitude ocean, we can not rule out a significant slowing of the Atlantic conveyor in the next 100 years.

And since the 1970 ′ s on average there's about a 4 % increase in water vapor over the Atlantic Ocean and when that gets caught into a storm, it invigorates the storm so the storm itself changes, and that can easily double the influence of that water vapor and so you can get up to an 8 % increase, straight from the amount of water vapor that's sort of hanging around in the atmosphere.

Emanuel (2005) makes a compelling case that the warming ocean temperatures (and associated changes in atmospheric temperature and humidity profiles) are behind the increased TC intensity in the Atlantic.

Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the water) and evaporation (increases the salinity by removing water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions from the two gyres could explain the high salinities in the in - flow regions.

I haven't read the papers and don't know what is happening with salinity in the rest of the Atlantic, but looking at your map it occurred to me that if there was increased freshwater in the Northern Ocean due to ice melting and increase salinity in the tropical Atlantic due to increased evaporation, couldn't a mixing effect at the southern edge of the Northern ocean as tropical water is circulated north show similar resOcean due to ice melting and increase salinity in the tropical Atlantic due to increased evaporation, couldn't a mixing effect at the southern edge of the Northern ocean as tropical water is circulated north show similar resocean as tropical water is circulated north show similar results?

(They also loudly attacked climate modelers for not reproducing data on ocean cooling (which turned out to be due to some faulty instruments on Argo floats), and then just as loudly promoted results from models that predicted increased wind shear in the Atlantic.)

As with our previous work, it is the Atlantic Ocean that contributes most to the increase in heat content.

For the Atlantic, Pacific, and Indian Oceans the increases of heat content (linear trends) are respectively 7.7, 3.3, and 3.5 x 1022 J.

Atlantic tropical cyclones are getting stronger on average, with a 30 - year trend that has been related to an increase in ocean temperatures over the Atlantic Ocean and elsewhere 1 &mdasocean temperatures over the Atlantic Ocean and elsewhere 1 &mdasOcean and elsewhere 1 — 4.

Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler in the nearest deep convection source region of the South Atlantic near Africa and the Equator, warm over the bulk of the North Atlantic, strongly warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of cold water from the north whenever the Gulf Stream is running quickly.

Observations in the tropical Atlantic ocean (11) show that the clear sky downwelling infrared flux incident on the surface (Fa ---RRB- also increases faster than the surface emission with increasing SST.

However, at the same time, there's been the steady increase in subtropical ocean surface temperatures in the Atlantic Warm Pool, leading to record water temperatures off the US east coast in winter, which tends to fuel more extreme storms (via the increase in water vapor pressure over the warmer ocean).

Is the rather definitive statement that «The increased activity since 1995 is due to natural fluctuations (and) cycles of hurricane activity driven by the Atlantic Ocean itself along with the atmosphere above it and not enhanced substantially by global warming» at all supportable?

The increased mid-latitude westerlies in the North Atlantic can be largely viewed as reflecting either NAO or NAM changes; multi-decadal variability is also evident in the Atlantic, both in the atmosphere and the ocean.

Ocean surface cooling, in the North Atlantic as well as the Southern Ocean, increases tropospheric horizontal temperature gradients, eddy kinetic energy and baroclinicity, which drive more powerful storms.

Only in certain regions, notably in the Antarctic and northwest Atlantic Oceans, does a combination of evaporation (which increases the water's salt content) and wintertime cooling make surface water dense enough to sink all the way down.

Moreover, changes in models often affect climate simulations in ways that are understandable in physical, real - world terms; increasing an ocean - model's resolution, for example, makes the simulated Gulf Stream stronger, and thus enhances heat transport to the North Atlantic.
