Using observations and a coupled Earth system model, a new study shows that the decline of the Atlantic major hurricane frequency during 2005 — 2015 is associated with a weakening of the AMOC.

In a recent paper published in Nature Communications, using both observations and a coupled Earth system model (GFDL - ESM2G) with a more realistic simulation of the Atlantic Meridional Overturning Circulation (AMOC) structure, and thus reduced mean state biases in the North Atlantic, the authors show that the decline of the Atlantic major hurricane frequency during 2005 — 2015 is associated with a weakening of the AMOC directly observed from the RAPID program.

For problems with coherent features, such as hurricanes, thunderstorms, firelines, squall lines, and rain fronts, there is a need to adjust the numerical model state by deforming the state in space (its grid) as well as by correcting the state amplitudes additively.

[24] For hurricane evacuation studies, a family of storms with representative tracks for the region, and varying intensity, eye diameter, and speed, are modeled to produce worst - case water heights for any tropical cyclone occurrence.

Here's why: One of our most accurate, highest - resolution hurricane models — the Hurricane Weather Research and Forecast system — has been strongly hinting that nothing much will happen with 99L until late Saturday or early Sunday, at which point a period of rapid intensification could make the storm blossom quickly into a hhurricane models — the Hurricane Weather Research and Forecast system — has been strongly hinting that nothing much will happen with 99L until late Saturday or early Sunday, at which point a period of rapid intensification could make the storm blossom quickly into a hHurricane Weather Research and Forecast system — has been strongly hinting that nothing much will happen with 99L until late Saturday or early Sunday, at which point a period of rapid intensification could make the storm blossom quickly into a hurricanehurricane.

Often the domain we define for the model may move along with the hurricane.

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.

Data from an ocean glider equipped with a host of scientific instrumentation and deployed ahead of the storm allowed researchers not only to see how sediment was being redistributed by the hurricane as the storm unfolded but also to compare their real - life observations with forecasts from mathematical models.

However, a confident assessment of human influence on hurricanes will require further studies using models and observations, with emphasis on distinguishing natural from human - induced changes in hurricane activity through their influence on factors such as historical sea surface temperatures, wind shear, and atmospheric vertical stability.

Remember, for these «hurricane models», you are trying to deal with a much higher resolution (or more regional effects which are more weakly modeled so far) than «climate models» which deal with easier - to - model larger affects... ie.

With an active hurricane season predicted, might be interesting for a sociological model based on this premise to be overlaid onto a climatological model.

Further investigation with more advanced models is needed for more confident projections of future hurricane activity in a warming climate.

The GFDL hurricane model (with a grid spacing as fine as 9 km) is able to simulate the frequency, intensity, and structure of the more intense hurricanes, such as category 3 - 5 storms, much more realistically than the regional (18 km grid) model.

This model, when forced with observed sea surface temperatures and atmospheric conditions, can reproduce the observed rise in hurricane counts between 1980 and 2012, along with much of the interannual variability (Figure 5).

However, using the CMIP3 and CMIP5 multi-model climate projections, the hurricane model also projects that the lifetime maximum intensity of Atlantic hurricanes will increase by about 5 % during the 21st century in general agreement with previous studies.
