tsunami 3 Flashcards
charcateristics of eyewall
This is where the most severe weather in the typhoon occurs—strongest winds, heaviest rainfall, and the highest storm surges.
Why the eyewall Matters:
The eyewall is responsible for the most damage as it directly affects the areas where it makes landfall. The wind speeds in this part can reach over 250 km/h (155 mph) in powerful typhoons.
These are bands of clouds and thunderstorms that spiral outward from the eyewall.
- Rainbands (Spiral Bands)
characteristics of eyewall
They can extend hundreds of kilometers from the center of the typhoon, bringing heavy rains and gusty winds in waves.
Why the rainbands Matters:
Rainbands can lead to flooding and landslides even in areas that are far from the center of the typhoon. They are often responsible for heavy rainfall long before and after the eye passes.
consists of air that spirals outward from the top of the typhoon, creating a cloud shield that can cover an area much larger than the storm itself.
The outflow
characteristics of outflow
It helps to ventilate the typhoon by allowing warm, moist air to rise in the storm’s core and escape at the top
Why the outflow Matters:
Strong outflow allows the typhoon to strengthen by facilitating more convection (upward movement of warm air). A well-developed outflow often indicates a stronger storm.
PAGASA
stands for the Philippine Atmospheric,
Geophysical, and Astronomical Services
Administration. It is the government agency
responsible for weather forecasting, monitoring, and
reporting on weather conditions in the Philippines. PAGASA provides information on tropical cyclones,
including typhoons, to help prepare and inform the
public about potential hazards.
They also issue public storm warning signals that
indicate the intensity and potential impact of a
tropical cyclone in specific areas of the country,
allowing for better preparation and response.
PAR
The Philippines Area of Responsibility is a
specific region in the western Pacific Ocean
monitored by the Philippine Atmospheric,
Geophysical, and Astronomical Services
Administration (PAGASA) for tropical cyclones.
This area helps PAGASA determine when a tropical
cyclone will affect the Philippines and allows them
to issue timely warnings.
