Global warming makes Typhoon more or stronger?

The mainstream conclusion of the scientific community: The total number of Typhoons does not necessarily multiply, but the Severe Typhoon ratio increases, precipitation is more extreme, rapidly increases more frequently, and the impact range toward high latitudes expansions.

Has the typhoon increased?

许多人感觉Typhoon 越来越多, 但观测统计显示, Northwest Pacific年均Typhoon formed数 (约26个) 近几十年No significant increase in trend.Some studies even suggest a slight reduction. " Feeling more" more comes from spreading Zoom in and the effects intensified.

But typhoon is indeed changing" terrible"

The Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) and mainstream research pointed out Trends:

• Severe Typhoon Rate Rising: An increase in the percentage of reaching Severe Typhoon and above levels – the total number remains unchanged, but the"hard role" percentage is higher.
• More extreme rainfall.Typhoon Rain Intensity increases, and Extreme rainstorms caused by Doksuri, Morakot, and Taiwan mountain rainfall reflects this extreme.
• Increase more frequently.The warming sea layer deepens, the number of cases of two levels of Typhoon surges within 24h, and more occurs in nearby seas — less time left for defence.
• Expansion of scopeTyphoon reached peak intensity Position toward High latitude Moving, risk rising in regions that were previously less affected by Typhoon positive (NP, JapanN, Korea).
• Moving speed or slowing down.Some studies suggest that typhoon movements decrease by about 10 percent, and slow walking means that the storms last longer in the same area, and the cumulative rainfall is larger.

Supplemental Effect of Sea Level Rise

The global sea level has risen by more than 20 centimeters than before industrialization.The same intensity of storms, overlapping higher underlying sea levels, and the risks of dams and water overflow are significantly increased—this is the "slow variable + acute variable" compound risk facing coastal city.

Revelation to ordinary people.

• Historical experience is failing": "We have never been into the water here" is no longer a reliable judgment
• Attention to Fast Enhanced Early Warning, Near Sea Typhoon's Intensity Jump May Be Overnight
• Inland City also needs to pay attention to the extreme risk of rainfall from Typhoon's residual flow
