Sentences with phrase «greater storm intensities»

Globally, estimates of the potential destructiveness of hurricanes show a significant upward trend since the mid-1970s, with a trend towards longer lifetimes and greater storm intensity, and such trends are strongly correlated with tropical SST.

The increase comes about because of longer storm lifetimes and greater storm intensity, and the index is strongly correlated with tropical SST.

Globally, estimates of the potential destructiveness of hurricanes show a signifi cant upward trend since the mid-1970s, with a trend towards longer lifetimes and greater storm intensity, and such trends are strongly correlated with tropical SST.

At 600ppm, global average temperature rise could be in the range of 3 - 4Â °C — which means greater sea level rise than predicted, glaciers melting and constraining water supply throughout large areas of Asia, agriculture being severely stressed in many places, greater storm intensity, reduced biodiversity, the end of coral reefs.

Not exact matches

The Dubai case was particularly astounding to the researchers given that the models suggested even a moderate - intensity storm could generate an extremely high surge, and that under the right circumstances, a strong storm could reach intensities far greater than even the most intense storm on record with a surge up to 23 feet (though these would be 3 to 20 times rarer than a 10,000 - year storm).

While there is a good theoretical case for greater damage from tropical storms, there is evidence that mid latitude storms may have decreased in intensity compared to the Middle ages, and a good theoretical case that they should decline in intensity due to global warming.

but as the oceans are warming, there is less relative difference between the warm and cool, so less frequent release, meaning fewer storms, but of greater intensity.?

Tropical cyclones are responsible for the vast majority of loss of property and life and the level of scientific uncertainty regarding genesis and intensity of TCs is greater than extratropical, baroclinic storms.

HOWEVER, the number of tropical cyclones with intensity greater than 34 - knots has remained at the 30 - year average (83 storms per year).

Since daily ACE represents a 4 - times daily sum of wind speed squared, an «average» September 21st could see one of the following (among other combos): One TC at 125 knots Two TCs at 90 knots Three TCs at 70 knots or Six TCs at 50 knots Current TCs = 0 September 15: Global Hurricane Frequency [storms with maximum intensity greater than 64 knots] has dramatically collapsed during the past 2 - 3 years.

For the entire Northern Hemisphere, there is evidence of an increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total seasonal snowfall has generally decreased in southern and some western areas, 16 increased in the northern Great Plains and Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of increased blocking (a large scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.

The IPCC and associated Climategate scientists have claimed that human - induced global warming was producing unprecedented storm activity, with greater frequency and intensity.

[A] nthropogenic climate change is expected to lead to a greater incidence of high - intensity hurricanes, which together with rising sea level, will produce increased risk of storm surge flooding, while hurricanes are projected to produce substantially more precipitation as the atmosphere and oceans warm.

«Severe storms are happening more often and it feels like with greater intensity across Alberta, so it's essential that people have their own emergency preparedness plan and know what to do when bad weather strikes,» he said.

The intensity of storm systems is increasing and this means sewer infrastructure has greater demand than ever before.
