將氣象災害（主要是風災、澇災和旱災）對廣州市的影響程度分成輕微、偏輕、中等、偏重和嚴重五個級別，在時間上將未來10年分成三個時期：近期（ 2000 2002年） 、中期（ 2003 2006年） 、遠期（ 2007 2010年） ，通過對廣州市57名長期從事災害研究的專家的調查，再運用專家評估法，結果表明：在三種災害中，對廣州市影響最大的是風災，未來10年幾乎每年都有熱帶氣旋影響廣州，造成較大程度的損失，其損失程度約比中等年份偏多10 15 ;澇災對廣州市的影響在近期比臺風小，中期與臺風的影響接近，至遠期的影響超過臺風，整個預測期內比中等年份偏多10左右。If the last day of the period is a public holiday or a gale warning day ( i. e. tropical cyclone warning signal no. 8 or above is in force ), the period shall include the next normal working day. applications are considered to have been formally made only when they are received by the social welfare department

表一: 1954年以來熱帶氣旋影響香港期間錄得的最大風暴潮和最高水位Winter brings cool, dry weather with many bright days, while during the summer - the monsoon season, the weather is warm and humid, and rainstorms can be expected. between july and september is the most likely time for typhoons. there are five levels of tropical cyclone warning starting with 1 ( the lowest and least intense ) through 3, 8, 9 to 10 ( the highest and most critical )
香港的冬季大部份是乾爽涼快的晴天；夏季則屬季侯風季節，天氣溫暖潮濕，時有暴風雨， 7月至9月期間為香港的臺風季節，熱帶氣旋分為5級，由1級（最低程度及風力最弱）開始，然後可遞升至3 、 8 、 9及10級（最高程度及風力最強） 。Red lines denote the mean annual number in quiet and active periods

風暴潮頻率在全球氣候變暖后的可能變化已引起了廣泛的關注，而目前研究者們通過模擬與觀測所獲得的結論並不一致，基於此，本文從地質時期氣候冷暖變化與熱帶氣旋頻率變化之間的關系對這一問題作了驗證與探討。The relationship between cef and china summer rainfall and that between cef and tropical cyclone frequence ( tcf ) in the northwest pacific ( nwp ) are investigated. lt is found that the several branches of cross - equatorial flow have different interannual variability. periodicity and interdecadal variability. the five channels in the lower troposphere in the monsoon region of the eastern hemisphere have different relationships with china summer rainfall. the results also show that there are obvious relation between the interannual variatin of cef and tcf from july to october in the northwest pacific

但今年同期副熱帶高壓脊並沒有西伸至華南，使西北太平洋上引導氣流的方向比正常偏北，在該區的熱帶氣旋因此偏向北移，而不向西進入南海（In 2002, 2003 and 2004, respectively 7, 8 and 8 tropical cyclones occurred over the northern part of the south china sea, all below the long - term average of 12. thus, these 3 years may be regarded as a quiet period
2002 ， 2003 ， 2004這三年，南海上出現的熱帶氣旋分別為7 ， 8 ，和8個，都比長期平均的12個少，這幾年可以說是處于"平淡期" 。Thus, it is likely that the periodic patterns observed in tropical cyclone activity in the western north pacific and the south china sea are related to the oscillations of different periods in the atmosphere
相連的。大氣內不同周期的振蕩，是西北太平洋與南海熱帶氣旋活動呈周期性變化的原因之一。On inter - decadal time scales, tropical cyclone activity over the western north pacific seems to have a periodicity of about 18 years. this may be related to the pacific decadal oscillation see

熱帶氣旋及黑色暴雨警告生效期間的安排In this paper, the circulation of 20hpa transits to anticyclone type first ( at april the twenty - fourth averagely ) and then the transition transmit downwards, 54 days later it arrive to 70hpa ( at june the seventeenth averagely ). the interannual variation of transition dates in higher layers of middle stratosphere ( 10hpa 20hpa and 30hpa ) is more remarkable than in lower ones ( 50hpa and 70hpa ). the transition dates of 50hpa and 70hpa have notable interdecadal variation feature : they are sooner before 1978 and later after 1978
多年平均20hpa環流最先轉為反氣旋型（平均在4月24日） ，然後逐漸下傳，至70hpa （平均在6月17日）歷時54天；而中平流層上部（ 10hpa 、 20hpa和30hpa ）轉型日期的年際差異較下部（ 50hpa 、 70hpa ）大； 50 、 70hpa層環流轉型日期具有明顯的年代際變化特徵， 1978年以前轉型日期偏早， 1978年以後偏晚。Embryonic storm cells will never be able to develop further under prevailing unfavourable climatological conditions and this is why the south atlantic and the eastern south pacific are devoid of tropical cyclones
在南太平洋東部及南大西洋，因長期受到不利的氣候環境支配，風暴的初始胚胎受先天限制，無從發展，熱帶氣旋亦因而絕跡。分享友人
