  3. Typhoon Tropical cyclones normally occur during the months of May to November, and are particularly prevalent during September. Tropical cyclone advisory bulletins and/or warnings are issued by the Hong Kong observatory whenever a tropical cyclone centres within 800 km of Hong Kong poses a threat to the territory. These advisory bulletins include the tropical cyclone warning signal issued and its significance, the latest position and expected movement of the centre of the tropical cyclone, information on the wind strength, rainfall and sea level in the territory and advice on precautionary measures. 回主頁

  4. Lighting • Lightning is the working project name for an extension to tightly integrate calendar functionality (scheduling, tasks, etc.) into Thunderbird. 回主頁

  5. Rainstorm • Rainstorm Warning Signals • When the Amber Rainstorm Warning Signal is issued, it gives alert about potential heavy rain that may develop into Red or Black Rainstorm Warning Signal situations. There will be flooding in some low-lying and poorly drained areas. • The Red signal means that heavy rain could cause serious road flooding and traffic congestion, and may affect schools and public examinations. • The Black signal means that there are major disruptions and inclement weather. The public will be given clear advice on the appropriate actions to take. 回主頁

  6. Tsunami • Tsunamis, also called seismic sea waves or, incorrectly, tidal waves, generally are caused by earthquakes, less commonly by submarine landslides, infrequently by submarine volcanic eruptions and very rarely by a large meteorite impact in the ocean. Submarine volcanic eruptions have the potential to produce truly awesome tsunami waves. 回主頁

  7. Tornado Tornadoes are one of nature's most violent storms. In an average year, about 1,000 tornadoes are reported across the United States, resulting in 80 deaths and over 1,500 injuries. A tornado is a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long. 回主頁

  8. Blizzard • Blizzards are characterized by low temperatures (usually below 20°F) and accompanied by winds that are at least 35 mph or greater, there must also be sufficient falling and/or blowing snow in the air that will frequently reduce visibility to 1/4 mile or less for a duration of at least 3 hours. 回主頁

  9. hurricane A hurricane is a severe tropical storm that forms in the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, or the South Pacific Ocean east of 160E. Hurricanes need warm tropical oceans, moisture and light winds above them. If the right conditions last long enough, a hurricane can produce violent winds, incredible waves, torrential rains and floods. When hurricanes move onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge. Storm surge is very dangerous and a major reason why you MUST stay away from the ocean during a hurricane. 回主頁

  28. Waterspout A waterspout is a fast rotating column of air (made visible by water droplets in the cloud) extending from the base of a convective cloud to the water surface. It is equivalent to a tornado, which occursover land. A rotating column of air which does not touch the surface (water or land surface) is called a funnel cloud. 回主頁
