Notes 備註:

1. El Nino and La Nina episodes are defined here as the Oceanic Nino Index being larger than 0.5 degrees Celsius in absolute value (+ve for El Nino; -ve for La Nina) in 5 consecutive months. Events are broken down further into weak (0.5 - 0.9 Celsius degrees anomaly), moderate (1.0 - 1.4 Celsius degrees anomaly) and strong (>= 1.5 Celsius degrees anomaly. Abbreviations used: El: El Nino episode；La: La Nina episode；+: Strong；o: Moderate; -: Weak。當連續 5 個月的海洋 Nino 指數超越 (低於) 0.5 (-0.5) 攝氏度時，我們說厄爾尼諾 (拉尼娜) 現象已經出現。每種現象會在被細分為 "弱" (絕對值距平 0.5 - 0.9 攝氏度)、"中等" (絕對值距平 1.0 - 1.4 攝氏度) 和 "強" (絕對值距平最少 1.5 攝氏度)。本表所用縮寫：El: 厄爾尼諾年；La: 拉尼娜年；+: 強；o: 中等; -: 弱。

2. Defined as number of TCs necessitating TC signals. Subsequent visits of the same storm are ignored (e.g. 2007 Pabuk). 為該年令香港天文台發出熱帶氣旋信號的氣旋數目。一個熱帶氣旋即使令天文台發出多於一次熱帶氣旋警告信號亦只作一次計 (例如 2007 年帕布)。

3. Not available. 未有資料提供。

4. From HKO Website: "In 1931, the signals were amended to 1 to 10 with signals 2 and 3 signifying strong winds from SW and SE respectively, signal 4 being a non-local signal, signals 5 to 8 signifying gales from the four quadrants, namely NW, SW, NE ad SE, signal 9 signifying increasing gales and signal 10 indicating the threat of hurricane force winds. Signals 2, 3 and 4 were used intermittently afterwards and were discontinued in the late 1930s. In 1956, the No. 3 Strong Wind Signal was introduced between the No. 1 Stand-by Signal and the gale signals. Starting from 1 January 1973, signals 5 to 8 were replaced by 8 NW, 8 SW, 8 NE and 8 SE respectively so as to avoid misunderstanding by the public. This system has been in use ever since." 由天文台網頁節錄 : "一九三一年更改為1至10號，其中2號及3號分別表示強風由西南及東南方向吹襲本港，4號為非本地信號，5號至8號分別代表來自西北、西南、東北或東南四個方向之烈風，9號則代表烈風風力增強，10號代表颶風吹襲。此後2、3、4號信號時有時無，到一九三零年代後期被取消。一九五六年在1號戒備信號及5號烈風信號之間加上3號強風信號。為了避免引起公眾之混淆，由一九七三年一月一日開始，5號至8號風球分別由8號西北、8號西南、8號東北及8號東南四個信號代替。這信號系統一直沿用至現在。"
