Sentences with phrase «influence hurricane intensity»

These cycles definitely do influence hurricane intensity, but they can't be the whole story, Curry said.

Of these factors, only rising sea surface temperature was found to influence hurricane intensity in a statistically significant way over a long - term basis.

... «dust emissions have a wide impact on climate and weather, from modifying rainfall thousands of miles away, to influencing hurricane intensity and affecting air quality».

Not exact matches

Recent advances have improved NOAA's intensity forecasts by 20 percent, but there are so many variables influencing the developing of a hurricane — from the energy they draw from the oceans to their interactions with the surrounding environment and their dynamic inner cores — that storms like Matthew befuddle many experts.

When discussing the influence of anthropogenic global warming on hurricane or tropical cyclone (TC) frequency and intensity (see e.g. here, here, and here), it is important to examine observed past trends.

If we're considering the risk of hurricane damages, and not just overall basin activity, then the effect of increased vertical wind shear would seem to be (at least) twofold — it not only reduces potential intensity, but it also influences the steering of hurricanes (since hurricanes are basically steered by the background flow plus a beta drift).

Based on the results of the causality tests, the author concludes that it is global near - surface air temperature that influences sea surface temperature, and not the other way around — which supports the global warming - induced increase in hurricane intensity.

So, on the one hand you have the claim that Atlantic hurricane intensity is controlled by the AMO, whose mechanism is poorly understood but which has something to do with the meridional overturning circulation, which is influenced by the sinking of water off of Greenland.

On the question of hurricanes, the theoretical arguments that more energy and water vapor in the atmosphere should lead to stronger storms are really sound (after all, storm intensity increases going from pole toward equator), but determining precisely how human influences (so including GHGs [greenhouse gases] and aerosols, and land cover change) should be changing hurricanes in a system where there are natural external (solar and volcanoes) and internal (e.g., ENSO, NAO [El Nino - Southern Oscillation, North Atlantic Oscillation]-RRB- influences is quite problematic — our climate models are just not good enough yet to carry out the types of sensitivity tests that have been done using limited area hurricane models run for relatively short times.

A (2) Modern warming, glacier and sea ice recession, sea level rise, drought and hurricane intensities... are all occurring at unprecedentedly high and rapid rates, and the effects are globally synchronous (not just regional)... and thus dangerous consequences to the global biosphere and human civilizations loom in the near future as a consequence of anthropogenic influences.

[Response: This is just two bits of speculation on my part, but it is conceivable that a) the influence of ENSO is of a different character than the influence from SST (i.e. there is more happening than a similar increase in hurricane intensity / number), and ii) the different frequency distribution of ENSO events compared to variations in SST (or PDI) mean that the signal is stronger compared to the noise in that frequency band.
