We use this index instead of the NAO, as the AMO is strongly correlated with thermohaline and atmospheric circulation patterns [26] as well as storm activity [27], [28] in the subtropical - temperate region where Atlantic juveniles reside [17].

The revised AMO index (Trenberth and Shea, 2006) indicates that North Atlantic SSTs have recently been about 0.3 °C warmer than during 1970 to 1990, emphasizing the role of the AMO in suppressing tropical storm activity during that period.

The end of November means that both the Atlantic and East Pacific hurricane seasons have drawn to a close, and storm activity in the two ocean basins was quite different, indeed, but for the same reason.

Those unexpectedly warm waters were what caused some of the seasonal forecasts to slightly underestimate the amount of storm activity in the Atlantic, Philip Klotzbach, a hurricane researcher and seasonal forecaster at Colorado State University, wrote at the Capital Weather Gang blog.

The North African country of Morocco lies directly in the path of all major North Atlantic swell activity, yet is far enough south (between 20N and 35N) to avoid the same storms and weather fronts that pound Europe.

Emanuel found a close correlation between increases in this measure of hurricane activity (which is likely a better measure of the destructive potential of the storms than previously used measures) and rising tropical North Atlantic SST, consistent with basic theoretical expectations.

While many studies of the effects of global warming on hurricanes predict an increase in various metrics of Atlantic basin - wide activity, it is less clear that this signal will emerge from background noise in measures of hurricane damage, which depend largely on rare, high - intensity landfalling events and are thus highly volatile compared to basin - wide storm metrics.

If so, this is one way in which global warming may end up causing a decrease in Atlantic hurricane activity over the coming decades, since the increased wind shear over the Atlantic during El Niño events greatly reduces the number and intensity of these storms.»

The study looked at historical hurricane activity across the entire tropical Atlantic basin to see if the current peak in storm numbers is... Read more

CNN: One of the factors which has prompted US scientists to warn of intensified hurricane activity in the Atlantic this year is warmer water temperatures, linking storm frequency with climate change.

Although the age model gives some uncertainty in the timings, it appears that storminess increased at the onset and close of North Atlantic cold events associated with oceanic changes, with reduced storm activity at their peak.

Nearly one year after Hurricane Sandy ravaged the East Coast, the 2013 Atlantic Hurricane Season has not produced a single land - falling hurricane in the U.S. Instead of having above - average storm activity, as the seasonal hurricane outlooks unanimously called for, the season has been quiet — notable for its inactivity.

Low storm activity occurred during the Spörer Minimum linked to an acceleration of the Atlantic Meridional Overturning Circulation (AMOC).

There has been a substantial increase in most measures of Atlantic hurricane activity since the early 1980s, the period during which high quality satellite data are available.20, 21,22 These include measures of intensity, frequency, and duration as well as the number of strongest (Category 4 and 5) storms.

According to the National Oceanic and Atmospheric Administration Climate Prediction Center, which has updated its 2015 Atlantic Hurricane Season Outlook, there is a 90 % chance of a below - normal hurricane season and a lower chance of expected storm activity in the United States this year.

I note that the recent paper shows a dramatic uptick in storm activity that has been convincingly refuted by «strong evidence that there has been no systematic change in the number of north Atlantic tropical cyclones during the 20th century.»

The study looked at historical hurricane activity across the entire tropical Atlantic basin to see if the current peak in storm numbers is anomalous.

There has been a substantial increase in most measures of Atlantic hurricane activity since the early 1980s, the period during which high - quality satellite data are available.13, 14,15,16,17 These include measures of intensity, frequency, and duration as well as the number of strongest (Category 4 and 5) storms.

The revised AMO index (Trenberth and Shea, 2006) indicates that North Atlantic SSTs have recently been about 0.3 °C warmer than during 1970 to 1990, emphasizing the role of the AMO in suppressing tropical storm activity during that period.

These multi-decadal fluctuations in hurricane activity result nearly entirely from differences in the number of hurricanes and major hurricanes forming from tropical storms first named in the tropical Atlantic and Caribbean Sea.

If you were to inject SO2 into the Northern Hemisphere, the models show, you would reduce storm activity in the North Atlantic — probably because the injection would put the tropical jet stream on a collision course with the Atlantic hurricane main development region.

Tropical storm activity in the Atlantic Ocean, the Caribbean, and the Gulf of Mexico has increased during the past 20 years.

Over the past 50 years there has been a strong statistical connection between tropical Atlantic sea surface temperatures and Atlantic hurricane activity as measured by the Power Dissipation Index (which combines storm intensity, duration, and frequency).

NCDC / NOAA Atlantic Hurricane Season: The recent average (1997 - 2006) seasonal hurricane activity in the North Atlantic basin is 14.4 named storms, 7.8 hurricanes and 3.6 major hurricanes.

- and data on the frequency of North Atlantic tropical storms going back to 1851 show strong minima of hurricane activity in the periods centered around 1850, 1915, and 1980 and maxima centered around 1875, 1950, and at the end of the time series (Elsner et al. 1999)-- these variations are approximately in phase with the AMO (Knight et al. 2005).»

To try to gain insight on this question, we have first attempted to go beyond the ~ 50 year historical record of Atlantic hurricanes and SST to examine even longer records of Atlantic tropical storm activity and second to examine dynamical models of Atlantic hurricane activity under global warming conditions.

Our more recent late 21st century projections of hurricane activity continue to support the notion of increased intensity (~ 4 %) and near - storm rainfall rates (~ 10 to 15 %) for the Atlantic basin (Knutson et al. 2013) as well as for most other tropical cyclone basins (Knutson et al. 2015).

However, to gain insight on the influence of climate change on Atlantic tropical storm and hurricane frequency, we must focus on longer (> 100 yr) records of Atlantic hurricane activity since very strong year - to - year and decade - to - decade variability appears in records of Atlantic tropical cyclones.

Every 20 to 40 years, Atlantic Ocean and atmospheric conditions conspire to produce just the right conditions to cause increased storm and hurricane activity.

In making their seasonal outlook, which was released on May 23, NOAA cited a broad area of above - average sea surface temperatures in the North Atlantic Basin, a continuation of a natural cycle of above - average hurricane activity, and a lack of an El Niño event in the Pacific Ocean as reasons why there may be more storms this year.

«This year is looking like there will be just as much activity in the Atlantic, but it's too difficult to say with any accuracy whether any of those storms will hit Florida,» says Meyers.
