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
