Over the past decade, Hong Kong Weather Watch have been holding annual "Astronomical, Geographic and Meteorological Events" elections. The 2010s have officially come to a close with the arrival of 2020. We are now holding the "Events of the Decade" election for you to recollect the most unforgettable moments between 2010 and 2019.
The events in this poll are selected from the top ten events in the past ten years of the annual election. Due to an imbalance of the number of astronomical, geographic and meteorological events available, the current election is divided into the following four categories:
Hong-Kong-related tropical cyclone events;
Hong-Kong-related other meteorological events;
Meteorological events outside Hong Kong (including tropical cyclones);
Astronomical and geographic events (anywhere in the world).
In each category, ten events with the highest percentages of votes received in the past ten years are listed in the poll.
(The organizer would like to thank HKSON for creating the banner for the election, and MET WARN, Weblog 1097 and Modern Observatory for promoting the event. Banner design is from Freepik.)
