Error In Cutaway Figure Showing Northern Hemisphere Hurricane Structure

Northern hemisphere cyclones, including tropical ones, rotate counter-clockwise, not clockwise as shown in the diagram. The diagram is either a mislabeled southern hemisphere cyclone figure, or an incorrect (reversed) depiction of a northern cyclone.

See:

NOAA National Hurricane Center (NHC) Website:

http://www.nhc.noaa.gov/climo/

"Overview

A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation. Tropical cyclones rotate counterclockwise in the Northern Hemisphere. ..." [Emphasis added]

The creator of the graphic should be notified to make a proper change to the otherwise excellent figure.

I think the picture shows a northern cyclone, the wind arrows indicate a counterclockwise circulation. Only mistake is the word "clockwise" that should be changed in "counterclockwise". Koos van den beukel (talk) 09:34, 29 April 2016 (UTC)[reply]

Tropical Cyclone and Hurricane

By NOAA standards, a hurricane and a tropical cyclone are not the same. This warrants separate Wikipedia pages for each topic. there are distinctive scientific differences between a tropical cyclone, hurricane, tropical depression, and tropical storm. I currently do not poses adequate time, or knowledge to write a page on hurricanes. — Preceding unsigned comment added by 108.3.159.201 (talk) 23:25, 2 September 2016 (UTC)[reply]

This is a akin to when a white horse is not a horse. A hurricane is a special case of a tropical cyclone.--Jasper Deng (talk) 15:32, 7 October 2016 (UTC)[reply]

Ethymologies

It would be good to add the ethymology of the words. I precisely came looking for the ethymology of the word hurricane which i did not find. Thinker78 (talk) 04:05, 27 November 2016 (UTC)[reply]

Fighting hurricans from NOAA and kayuweboehm(at)yahoo.de

For darkening of 1 billion m² maybe 10g/m² overall 10 000t of black printer ink, fine powder coal or ash from a black snake are enough and black carbon smoke particles "Ruß" produced industrial (https://de.wikipedia.org/wiki/Ru%C3%9F#Herstellungsverfahren) can be blown up carried higher from alone inside a hurricane eye from a container ship stomach. Big container ships without containers are very stable, strong and can load up to 20 times that mass in stomach. Hurricans are always predicted for warnings with time left for interaction if likely dangerous with ships already out in hurricane seasons.

Special inside NOAA sides for same theme http://www.aoml.noaa.gov/hrd/tcfaq/tcfaqC.html with contra answer that the needed amount of given substances is practical possible and carried upwards from alone inside hurricane eyes.

The idea here is to spread a layer of sunlight absorbing or reflecting particles (such as micro-encapsulated soot, carbon black, or tiny reflectors) at high altitude around a hurricane. This would prevent solar radiation from reaching the surface and cooling it, while at the same time increase the temperature of the upper atmosphere. Being vertically oriented, tropical cyclones are driven by energy differences between the lower and upper layer of the troposphere. Reducing this difference should reduce the forces behind hurricane winds.

It would take a tremendous amount of whichever substance you choose to alter the energy balance over a wide swath of the ocean in order to have an impact on a hurricane. One would hope that this substance would eventually disperse or disintegrate and not have a terrible impact on the earth's ecology. Knowing where to place it would also be tricky. You don't want to heat up the wrong area of the atmosphere or you could put more energy into the cyclone. These proposals would require a great deal of precisely-timed, coordinated activity to spread the layer, while running the risk of doing more harm than good. Many computer simulations should be run before any field test were tried.
