Signal No.

The numerical designation of the wind signal level.

Wind Threat

The level of threat posed by the wind speed of a tropical cyclone.

Warning Lead Time

Super Typhoon Extreme Threat (STY)

A tropical cyclone with an extreme threat to life and property.

PSWS

Public Storm Warning Signal, a system used to provide guidance and instructions to the public during a typhoon.

Squalls

Strong winds associated with a tropical cyclone.

Tornadoes

Violent and destructive whirling winds accompanied by a funnel-shaped cloud, produced by a tropical cyclone.

Rainfall and Flooding

The amount of rainfall and resulting flooding caused by a tropical cyclone.

Storm surge

An abnormal rise of water along the coast caused by a tropical cyclone.

Emergency kit

A collection of basic items that a household should have in the event of an emergency, such as a typhoon.

Landforms

Natural features of the Earth's surface, such as mountains and valleys.

Leeward side

The side of a mountain or landform that is sheltered from the prevailing winds.

Windward side

The side of a mountain or landform that is exposed to the prevailing winds.

Rain shadow

A dry area on the leeward side of a mountain or landform, caused by the blocking of moisture by the windward side.

Moisture

Water vapor in the air.

Prevailing winds

The dominant winds in a particular area or region.

Bodies of Water

Refers to large bodies of water such as oceans and seas that play a crucial role in the formation and development of a typhoon.

Typhoon

A tropical cyclone characterized by strong winds and heavy rainfall, typically occurring in the western Pacific Ocean.

Warm Water

Water with a temperature of 26.5°C or higher, which is necessary for the development of a typhoon.

High Humidity

The presence of a significant amount of moisture in the air, which contributes to the formation of a typhoon.

Optimal Location

A specific geographical area that provides favorable conditions for the formation and intensification of a typhoon.

Vertical Wind Shear

The difference in wind speed and direction at different altitudes, which affects the development and structure of a typhoon.

Outflow

The movement of air away from the center of a typhoon, which helps maintain its circulation and strength.

Descending Air

Air that moves downward in the atmosphere, creating an area of high pressure and contributing to the formation of a typhoon.

Spiral Rain Bands

Bands of clouds and precipitation that spiral outward from the center of a typhoon.

Tropical Cyclone

A generic term for a low-pressure system that develops over tropical or subtropical waters, including typhoons.

Air Pressure

The force exerted by the weight of the atmosphere, which plays a role in the formation and behavior of a typhoon.
