super typhoon
strong winds + heavy rains + central low pressure area
typhoon
The center of the cyclone, usually calm and clear
eye
the most intense part surrounding the eye. Strongest winds, heaviest rainfall, and most destructive forces.
eyewall
Bands of heavy rain and thunderstorms spiraling outward from the center.
rainbands
sea temp you need to form a tropical cyclone
26.5 celsius
localized unusual increase of sea water level beyond the predicted astronomical tide level primarily due to intense winds and lowered atmospheric pressure
storm surge
flood that increase river water levels
riverine
flood that is caused by storm surges and unusually high tides
estuarine and coastal
flood wherein large areas of impermeable surfaces, man-made causes
urban flooding
flood that involves ground failure, liquefaction, landslides that may be triggered by natural disasters, breakage of dams
catastrophic
flood that is rapid and short lived, due to intense rainfall/collapse of dam
flash flood
cyclic fluctuation of warm and cold sea surface temperatures and atmospheric pressure in the central and eastern equatorial pacific
el nino southern oscillation
causes extreme regional-scale weather and climate pattern changes
el nino southern oscillation

el nino southern oscillation
it lasts for 9 months to 2 years, starts between dec to feb and occurs every 2-9 years
