Study Notes
Tropical Cyclones
- The maximum sustained windspeed for a Severe Tropical Storm (STS) is 48-63 kt (89-118 km/h).
- A tropical cyclone is a generic term used by meteorologists to describe a rotating, organized system of clouds and thunderstorms that originate over tropical water.
- The center of a cyclone is described as the most calm part, known as the "eye".
Weather Phenomena
- The presence of lightning and thunder characterizes a thunderstorm.
Storm Surge
- The primary hazard posed by a Storm Surge to coastal settlements is coastal flooding.
El Niño
- El Niño causes an increase in sea surface temperature across the central and east-central Pacific.
Cyclone Rotation
- In the southern hemisphere, the direction of rotation near the ground for tropical cyclones is clockwise.
Typhoons
- Typhoons are primarily found in the western Pacific Ocean.
Extreme Meteorological Phenomena
- Extreme meteorological phenomena include tropical cyclones, thunderstorms, tornadoes, and floods, and are collectively known as "severe weather".
Regional Cyclone Names
- Tropical cyclones in the South Pacific Ocean and Indian Ocean are referred to as "cyclones".
Explore the concept of hydrometeorological hazards and the different extreme weather phenomena like tropical cyclones, thunderstorms, tornadoes, and floods. Learn about the potential impacts on life, property, livelihood, and the environment. Understand the differences between storms such as hurricanes, cyclones, and typhoons.
