Sentences with phrase «tropical cyclone energy»

Maybe something along the lines of the last 40 years of accumulated tropical cyclone energy.

What if total tropical cyclone energy in the North Atlantic does increase greatly with AGW as some believe?

Not exact matches

The Accumulated Cyclone Energy (ACE) index of tropical cyclone activity also indicated a below - average season in the North Atlantic.

As the planet warms from increasing greenhouse gases, more energy is going into the oceans, which is an important component in the strength of hurricanes (also known as tropical cyclones).

Why can't the average tropical cyclone tap into the energy of a (baroclinic, hence associated with wind shear) jet stream, rather than being weakenned by it?

If tropical cyclone occurrence decreases, less of the heat is dissipated, and unless ocean circulation in some way compensates by transporting the additional thermal energy elsewhere (i.e. for example out of the «main development region» of the Atlantic) some day a storm will tap the enhanced energy source.

Accumulated cyclone energy (ACE) is a measure used by the National Oceanic and Atmospheric Administration (NOAA) to express the activity of individual tropical cyclones and entire tropical cyclone seasons, * particularly the North Atlantic hurricane season.

(2) low to mid-latitude coastal regions are already facing a greater likelihood of very intense tropical cyclones that are drawing energy from significantly warmer ocean waters.

Indeed, the very strong interannual variability of global hurricane ACE (energy) highly correlated to ENSO, suggests that the role of tropical cyclones in climate is modulated very strongly by the big movers and shakers in large - scale, global climate.

I have devoted 30 years to conducting research on topics including climate feedback processes in the Arctic, energy exchange between the ocean and atmosphere, the role of clouds and aerosols in the climate system, and the impact of climate change on the characteristics of tropical cyclones.

«With the exception of the South Pacific Ocean, all tropical cyclone basins show increases in the lifetime - maximum wind speeds of the strongest storms... Our results are qualitatively consistent with the hypothesis that as the seas warm, the ocean has more energy to convert to tropical cyclone wind.»

The paper urges caution in using economic losses of tropical cyclones as justification for action on energy policies when far more potentially effective options are available.

It finds in all cases that efforts to reduce vulnerability to losses, often called climate adaptation, have far greater potential effectiveness to reduce damage related to tropical cyclones than efforts to modulate the behaviour of storms through greenhouse gas emissions reduction policies, typically called climate mitigation and achieved through energy policies.

When comparing a category 5 and a category 6 tropical cyclone of the same duration, given the difference in their intensity characterized by maximum wind speed, the kinetic energy of the category 6 storm of 165 to 185 knots would be 139 % — 175 % higher than the category 5 storm of 140 knots, Lin said.

Brightness temperatures, a measure of microwave energy coming out of Earth's atmosphere, are useful in estimating the intensity of convection in tropical cyclones.

The warmer the water, the more energy gets sucked in the air and the faster a tropical cyclone develops into a hurricane and the more powerful this hurricane can grow — other complex meteorological factors left aside.

Now it is indeed hard to stop a full - blown hurricane, but you can perhaps starve a tropical cyclone by trying to cut off part of its energy supply.

It is this extra energy released from the warm water freezing which turns an ordinary cyclone into a powerful tropical cyclone.

Hybrid storms and climate change: Sandy, continues Emanuel, is a «hybrid storm» — in other words, it has characteristics of tropical cyclones (hurricanes) that get their energy from the warm ocean surface, but also of winter cyclones that get their energy from temperature contrasts in the atmosphere.

My favorite talk in the regular sessions was «Power Law and Scaling in the Energy of Tropical Cyclones» by A. Corral, A. Osso; J. LLebot.

In the researchers» words: «About 60 % of all tropical cyclones moving from waters off of Africa pass through 61.5 ° W south of 25.0 ° N, the remaining 40 % either moving north of 25.0 ° N, dying out or re-curving to the east of 61.5 ° W.» Chenoweth and Divine note that LACE is «highly correlated» with Carribbean basin - wide Accumulated Cyclone Energy (ACE) since 1899.

Hurricanes (Fig. 7) and other tropical cyclones can be thought of as heat engines that take energy in by evaporating warm ocean water, and eject it at a colder temperature near the tropopause after air rises and water condenses in the eyewall [14].

It will also be interesting to see plaintiffs explain this graph of accumulated cyclone energy in the light of their theory that man - made global warming is increasing hurricane strengths and frequencies (ACE is a sort of integration of hurricane and tropical storm strengths over time).

Both hurricanes and typhoons are strong tropical cyclones, which are storms that form over warm ocean waters, have a well defined center of circulation, and feed off of heat energy from the ocean.
