NHC uses the GFDL hurricane model as one of its main sources of forecast guidance.

The figure above shows the trend of hurricane intensity forecast errors over the last nine seasons and even indicates that in 2006, for the first time ever, the GFDL hurricane model produced intensity forecasts that had smaller average errors than those from the National Hurricane Center's official forecasts.

These ocean features are accounted for in the GFDL / URI coupled hurricane model.

But in the big picture, hurricane models adeptly forecasted Irma's ultimate path to the Florida Keys nearly a week before it arrived there, says Brian Tang, an atmospheric scientist at the University at Albany in New York.

With GOES - 16 and CYGNSS nearly online, scientists are looking forward to even better hurricane models thanks to even better data.

For every hurricane in the North Atlantic Basin between 1997 and 2013, they pulled information such as mean sea - level pressure and temperature as well as vertical temperature and humidity profiles, and entered it into a thermodynamic hurricane model that treats each storm as a gigantic heat engine.

In 1996, a collaboration began between scientists at GFDL and the University of Rhode Island (URI) to couple the atmospheric hurricane model to the Princeton Ocean Model.

Using this additional downscaling step, the GFDL hurricane model reproduces some important historical characteristics of very intense Atlantic hurricanes, including the wind speed distribution and the change of this distribution between active and inactive decadal periods of hurricane activity (Fig. 1 of Bender et al. 2010).

To help address these challenges, scientists run hurricane models calibrated with observations over the historical period to project future trends and understand the major factors driving these trends.

To investigate the question, Lin and Emanuel used a method pioneered by Emanuel where a higher - resolution hurricane model is nested inside a coarser climate model (as climate models can't resolve individual storms well), and the models are run numerous times so that tens of thousands of storms are generated.

GFDL and URI scientists have continued to transition the latest research advancements into the operational GFDL hurricane model, and this has resulted in a steady reduction in track forecast error since 1995.

«Our work can be directly applied to a hurricane model to help improve hurricane intensity predictions, which will help people make more informed decisions with regard to their safety,» said David Ortiz - Suslow, a Ph.D. candidate at the UM Rosenstiel School and lead author of the study.

To get a sense for how this probability, or risk of such a storm, will change in the future, he performed the same analysis, this time embedding the hurricane model within six global climate models, and running each model from the years 2081 to 2100, under a future scenario in which the world's climate changes as a result of unmitigated growth of greenhouse gas emissions.

To do so, he first embedded the hurricane model in three gridded climate analyses — simulations of global climate, based on actual data from the past — to simulate hurricane activity near Houston between 1980 and 2016.

But last year, the team was able to improve the resolution on its hurricane model, which helped improve the intensity predictions.

The paper does indeed describe how the hurricane modelling is done.

Meanwhile, high - resolution hurricane models can forecast the growth and path of tropical storms, but would require much greater computer power or eons of time to simulate the large samples of storms required for climate - change studies.

That means the «findings probably haven't faced as rigorous a review as they might have,» Ars Technica reported, but it does show Emanuel is confident in his hurricane modeling, which has already been peer - reviewed.

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 hurricane.

Our results indicate that the models employing the dissipative heat engine, in particular, the hurricane model of K. Emanuel, are incorrect.
