MHW intensity between 1982 — 1998 and 2000 — 2016 increased in over 65 % of the global ocean, most notably in all five western boundary current regions, where the mean warming has been considerably faster than the global average39, and most mid-latitude ocean basins (Fig. 1e).
He later continued: «Now that ocean temperatures are considerably warmer than they were a few decades ago, the maximum potential intensity a hurricane can reach is higher, and we should expect to see a few Patricias sprinkled among the inevitable phalanxes of major hurricanes that will assault our shores in the coming decades.»

but as the oceans are warming, there is less relative difference between the warm and cool, so less frequent release, meaning fewer storms, but of greater intensity.?
To the extent that this abrupt cooling event can be identified with ocean dynamics, regardless of whether it involves the GSA or an abrupt change in the intensity of the AMOC, it provides a plausible explanation of why the NH warmed less rapidly from around the time of the end of WW II to 1980 than the SH.
• El Niño, a natural cycle of ocean warming, can exacerbate both flooding and drought, along with storm intensity, wildfires and other factors in the «vicious cycle» of climate change.
-- Susan Solomon, Nature The Long Thaw is written for anyone who wishes to know what cutting - edge science tells us about the modern issue of global warming and its effects on the pathways of atmospheric chemistry, as well as global and regional temperatures, rainfall, sea level, Arctic sea - ice coverage, melting of the continental ice sheets, cyclonic storm frequency and intensity and ocean acidification.
Warmer waters increase storm intensity / precipitation and create coral bleaching, thus destroys the world's coral reef's, a ocean ecosystem «the rainforest of the ocean» and contains major food web's.
We can also observe the effects of global warming in worldwide glacier retreat, declining Arctic ice sheets, sea level rise, warming oceans, ocean acidification, and increased intensity of weather events.
«The implication is that the warmer oceans increased the risk of greater hurricane intensity and duration,» Trenberth said.
The paradox is that global warming could also increase the intensity of not just hotter - than - usual seasons but also cool or cold episodes that would trigger unusual or extreme weather responses far from the ocean's cool centre.
(07/08/2013) Warmer ocean temperatures will increase the frequency and intensity of tropical cyclones, typhoons and hurricanes in «most locations» this century, concludes a new study based on simulations using six global climate models.
Climate change will affect fisheries and aquaculture through gradual warming, ocean acidification and through changes in the frequency, intensity and location of extreme events.
That is because there are factors, like air and ocean circulation patterns, that affect both the rate and the intensity of the global warming.
When the intensity of ultraviolet light from the sun increases, temperature rises in this ozone rich air and weakens the downdraft, lowers the surface pressure and with it the strength of the trade winds that blow across the ocean to the low pressure zones that form over the warm waters that accumulate in the west.
So while admitting, there probably is a very modest amount of AGW in the current warming cycle, it could just as easily have been caused by: i) the effects of the huge increase in global irrigation, ii) tiny changes in the sun's radiation, and / or iii) the knock on effects of changes in the intensity and direction of ocean currents.
«The distribution, frequency and intensity of these events have increased across the globe and this study links this expansion to ocean warming in some regions of the North Atlantic and North Pacific oceans
A warming surface ocean is also likely to increase the density stratification of the water column (i.e., Steinacher et al., 2010), altering the circulation and potentially increasing the isolation of waters in an OMZ from contact with the atmosphere, hence increasing the intensity of the OMZ.
Furthermore warm ocean surfaces really do send the air circulation systems poleward whilst changes in the intensity of the polar high pressure cells work in opposition to those oceanic effects.
Towards the end of his presentation he added: «Some research suggests global warming is linked to rising ocean and sea surface temperatures in the tropical Atlantic and the Gulf of Mexico — which may have an impact on hurricane intensity.
The current Landsea / Trenberth / Emanuel discussion has been parsed by many to mean that Landsea claims that the number of hurricanes is constant, and Trenberth is claiming that their intensity should increase as global warming heats the ocean surface and these claims can both be true.
There are no hurricanes born over cold water, therefore, a much warmer ocean will expand the range, intensity and frequency of hurricanes.
The model simulations including this additional feedback still showed a similar percentage increase of hurricane intensity under warm climate conditions as the original model without ocean coupling.
The models heavily relied upon by the Intergovernmental Panel on Climate Change (IPCC) had not projected this multidecadal stasis in «global warming»; nor (until trained ex post facto) the fall in TS from 1940 - 1975; nor 50 years» cooling in Antarctica (Doran et al., 2002) and the Arctic (Soon, 2005); nor the absence of ocean warming since 2003 (Lyman et al., 2006; Gouretski & Koltermann, 2007); nor the onset, duration, or intensity of the Madden - Julian intraseasonal oscillation, the Quasi-Biennial Oscillation in the tropical stratosphere, El Nino / La Nina oscillations, the Atlantic Multidecadal Oscillation, or the Pacific Decadal Oscillation that has recently transited from its warming to its cooling phase (oceanic oscillations which, on their own, may account for all of the observed warmings and coolings over the past half - century: Tsoniset al., 2007); nor the magnitude nor duration of multi-century events such as the Mediaeval Warm Period or the Little Ice Age; nor the cessation since 2000 of the previously - observed growth in atmospheric methane concentration (IPCC, 2007); nor the active 2004 hurricane season; nor the inactive subsequent seasons; nor the UK flooding of 2007 (the Met Office had forecast a summer of prolonged droughts only six weeks previously); nor the solar Grand Maximum of the past 70 years, during which the Sun was more active, for longer, than at almost any similar period in the past 11,400 years (Hathaway, 2004; Solankiet al., 2005); nor the consequent surface «global warming» on Mars, Jupiter, Neptune's largest moon, and even distant Pluto; nor the eerily - continuing 2006 solar minimum; nor the consequent, precipitate decline of ~ 0.8 °C in TS from January 2007 to May 2008 that has canceled out almost all of the observed warming of the 20th century.
In a follow - up study, which appeared in the Journal of Climate (2001), NOAA scientists Knutson and Tuleya teamed up with Isaac Ginis and Weixing Shen of the University of Rhode Island to explore the climate warming / hurricane intensity issue using hurricane model coupled to a full ocean model.
As the Arctic melts, oceans rise and temperatures warm, bringing more moisture into the atmosphere, it's the intensity of storms that becomes a concern, not only their frequency.
[A] nthropogenic climate change is expected to lead to a greater incidence of high - intensity hurricanes, which together with rising sea level, will produce increased risk of storm surge flooding, while hurricanes are projected to produce substantially more precipitation as the atmosphere and oceans warm.
The reason for the increase in storm intensity is that as the planet warms, the temperatures of the atmosphere and of the ocean surface go up as well, leading to increased evaporation and an increased capacity for the air to hold moisture.
