Science Flashcards
Typhoon
Which direction of movement does the typhoon usually move?
Northwest
Tropical Depression:
61 kph Leadtime 36 hours.
Tropical Storm:
62–88 kph. within 24 hours.
Severe tropical
89–117 kph. Expected within 18 hours.
Typhoon
118-184 kph Time: Expected within 12 hours.
Super typhoon
more than 185 kph Expected within 12 hours or less.
Structure of typhoon 1
Eye: Calm, clear conditions at the center (light winds, no clouds, no rain,
high temperatures).
Structure of typhoon 2
Eyewall: Surrounds the eye; area of strongest winds and heaviest rain.
Structure of typhoon 3
Rainbands: Bands of clouds and precipitation spiraling outward from the
center.
Causes cyclonic circulation: Counterclockwise in the Northern
Hemisphere.
Coriolis effect
What are the conditions required for a typhoon to form?
Warm ocean water (minimum temperature 27 °C).
high humidity.
Low air pressure.
Favorable wind patterns.
Monitoring and Prediction
Philippine Atmospheric, Geophysical, and Astronomical Services
Administration, or (PAGASA).
Defined area where PAGASA monitors tropical cyclones.
PAR or philippine area of responsibility
Cloud Formation Leading to Cyclones:
Cumulonimbus Clouds: Associated with heavy rains, thunderstorms, and
potential cyclonic disturbances.
Where do typhoons come from?
Tropical cyclone in the Northwestern Pacific Ocean.
Where do Hurricanes
come from
Tropical cyclones in the North Atlantic, Central and Eastern
Pacific Oceans.
Where do Cyclones
Come from?
General term for tropical cyclones in the South Pacific and Indian Oceans.
Which direction does the coriollis effect turn to?
Clockwise or Counterclockwise?
Counterclockwise
What are the impacts of a typhoon?
Strong winds, heavy rainfall, floods, and storm surges. and Landslides, caused by saturated soil.
Difference Between Cyclones, Hurricanes, and Typhoons:
Distinguished by geographic location.
