Understanding Tropical Cyclones and Typhoons

Front

What are tropical cyclones?

Back

Warm-core low pressure systems associated with a spiral inflow of mass at the bottom level and spiral outflow at the top level.

Front

Where do tropical cyclones typically form?

Back

Over oceans where sea surface temperature and air temperatures are greater than 26.5°C.

Front

What are the different names for tropical cyclones based on their location?

Back

Typhoons in the Northwest Pacific, cyclones in the Southwest Pacific and Indian Ocean, hurricanes in the Eastern Pacific and Atlantic.

Front

What is the 'eye' of a typhoon?

Back

The center of the storm, which is the calm part.

Front

What is the 'eye wall' of a typhoon?

Back

The part around the eye that has the strongest winds and rains, with winds that may blow up to 200 miles per hour.

Front

What are rain bands in a typhoon?

Back

Clouds that spin around the storm.

Front

How do landforms and bodies of water affect typhoons?

Back

Tropical cyclones can only form over oceans, and they weaken as soon as they move inland.

Front

Why is the Philippines prone to tropical cyclones?

Back

Due to its geographical location in the Pacific Ring of Fire, which produces heavy rains and flooding.

Front

How many typhoons does the Philippines experience on average per year?

Back

Approximately 19-20 typhoons.

Front

What are the processes involved in the formation of a typhoon?

Back

1. Evaporation of water at ocean surface temperatures of 26.5°C. 2. Convergence of air masses. 3. High humidity. 4. Warm air rises and cools, forming clouds.
