Sentences with phrase «resolution hurricane model»

In his new paper in the Proceedings of the National Academy of Sciences, he uses a procedure known as «downscaling» — combining together global climate models with a much higher resolution hurricane model — to show that hurricanes may be both more numerous and also more intense going forward.
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.
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.

Not exact matches

«In the low - resolution models, hurricanes were far too infrequent,» Wehner said.
What he found was that not only were the simulations much closer to actual observations, but the high - resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.
Emanuel and his colleagues had previously devised a technique to simulate hurricane development in a changing climate, using a specialized computational model they developed that simulates hurricanes at high spatial resolutions.
But there, challenges also arise, as models that simulate changing climate at a global scale do so at relatively coarse resolution, of around hundreds of kilometers, while hurricanes require resolutions of a few kilometers.
But last year, the team was able to improve the resolution on its hurricane model, which helped improve the intensity predictions.
«We tried to simulate the fundamental fluid dynamics and thermodynamics that control hurricane genesis in the Atlantic in a numerical model to a very high resolution
Higher resolution models tended to get more hurricane formation (perhaps unsurprisingly), with quarter - degree models parameterized using observed SSTs generally capturing historical hurricane formation rates fairly accurately.
# 34 Steve With regard to the hurricanes, how can the models predict an increase and measure the rate of that increase if the resolution is insufficient or if the absolute SST is not taken into account?
But the GFDL study is based on a state - of - the - art high - resolution model that is more appropriate for hurricane studies and provides important evidence suggesting that climate change may have an effect on the TCs.
What he found was that not only were the simulations much closer to actual observations, but the high - resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.
For example, the two models with the highest resolution (FLOR and HiFLOR) show increased extreme precipitation during the Atlantic hurricane season in the U.S. southeast.
With respect to hurricane intensity, there are observed trends indicating this and model results predicting this, and while there are problems in each (data problems with hurricanes, coarse resolution in global models, etc.), theoretical arguments also make clear that there will be more energy and water vapor available in the atmosphere to cause more intense hurricanes, so a very strong case can be made for this happening.
«Changes in extreme wind conditions related to small scale hurricane - type storms can not be skillfully detected in models that have a resolution to [o] coarse to resolve th [ese] storms»
* Changes in extreme wind conditions related to small scale hurricane - type storms can not be skillfully detected in models that have a resolution to coarse to resolve this storms.
Haarsma et al (http://onlinelibrary.wiley.com/doi/10.1002/grl.50360/abstract;jsessionid=885F86BAD593643C939DBD1032EC4B01.d04t02) use a high resolution model to make projections of changes in hurricanes reaching the European coast.
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.
As noted above, there is some indication from high resolution models of substantial increases in the numbers of the most intense hurricanes even if the overall number of tropical storms or hurricanes decreases.
The GFDL hurricane model used for the study is an enhanced resolution version of the model used to predict hurricanes operationally at NOAA's National Centers for Environmental Prediction.
The average intensity of the storms that do occur increases by a few percent (Figure 6), in general agreement with previous studies using other relatively high resolution models, as well as with hurricane potential intensity theory (Emanuel 1987).
Our 2015 study examines the impact of 21st - century projected climate changes (CMIP5, RCP4.5 scenario) on a number of tropical cyclone metrics, using the GFDL hurricane model to downscale storms in all basins from one of the lower resolution global atmospheric models mentioned above.
Most climate models available to scientists like Emanuel are too coarse in resolution to simulate the formation of hurricanes.
But Emanuel and his team developed one that can model hurricanes at high spatial resolutions within a changing climate.
