: : 請問大家:
: : cwb的風速 10分鐘跟1分鐘是會差多少阿???如果以每小51公尺來說的話
: : 還有請問大家美國華盛頓山吹出的每秒103公尺的風速
: : 是颶風吹出來的嗎????
: : 還有如果台灣真的被一個瞬間最大陣風超過每秒100公尺的颱風
: : 侵襲的話 台北101會一直晃來晃去嗎????
: : 還有住高樓的人會一直搖來搖去嗎??????
: : 大樓會倒嗎???

: 上網查了一下,找到這些:
: ● 風速最高的地區是出現在南極洲的聯邦灣 (常年大風),
: 風速達每小時322公里,即200英里。------------這是平均風囉?89.4m/s
: ● 最高地面風速 (高處) 的地區是出現在1934年4月12日的美國新罕布什爾的華盛頓山,
: 風速達每小時372公里,即231英里。------------103.3m/s

JTWC的PAKA報告
Commercial Port NWS HANDAR at Apra Harbor reported sustained/peak gust of
100/149 kt (51/77 m/sec) which is plausible; the Andersen AFB
anemometer recorded 96/205 kt (49/105 m/sec) which is not considered
representative. (無論如何都是相當驚人...Orz...)
The Commercial Port sensor failed after recording four hours of 135 to 149 kt
(69 to 77 m/sec) gusts in the wall cloud, Andersen AFB sensor lost power during
passage of the western wall cloud. (所以實際上更驚人? XD)
NPMOCW/JTWC anemometer at Nimitz Hill failed at 103 kt (53 m/sec) before the
wall cloud arrived, the wind bird at the Apra Harbor tide guage failed in the
wall cloud, and the NWS HANDAR at the University of Guam, Mangilao weathered
the storm to report a peak gust to 123kt (63 m/sec). ("才"這樣就掛了XD)
In the final analysis the HANDAR instrument at Apra Harbor becomes the
benchmark. It faithfully recorded peak gusts up to 149 kt (77 m/sec) until
the winds began backing to the southwest, at which point it failed.

Additionally, Andersen Air Force Base recorded a peak wind gust of 381 km/h
(236 mph),[12] which at the time was considered the highest wind speed on
record, surpassing the 1934 world record of 372 km/h (231 mph) on Mount
Washington in New Hampshire
However, a subsequent wind survey of the area discarded the reading at the
base, as it was considered unreliable

: ● 最高地面風速 (低處) 的地區是出現於1972年3月8日格陵蘭的卡亞納克,
: 風速達每小時333公里,即207英里。------------92.5m/s
: ● 通過雷達探測,龍捲風過程中的最高風速是出現於1999年5月3日美國
: 俄克拉馬州的俄克拉馬市,風速達每小時512公里,即318英里。----------142.2m/s

: 2、3項的高處低處的定義不知為何,
: 蘭嶼測站的高度不知屬於哪一個,
: 如果是屬低處,那離世界記錄真是不遠矣~@@
