Typhoons Flashcards
is a general term that refers to a severe weather condition that can be destructive to communities.
weather disturbance
what is weather disturbance
severe weather condition that can be destructive to communities
is a weather disturbance that can occur during any season in the Philippines. It is characterized by a heavy rain shower with lightning and thunder.
thunderstorm
What are thunderstorm clouds?
cumulonimbus clouds looks like large cauliflowers
is the release of electric charges in clouds.
Lightning
The sound waves produced by lightning generate what can be heard as
thunder
aside from thunder and lightning, what are thunderstorm brings?
hail, strong winds tornadoes
is a violently spinning column of air that extends from the base of a cumulonimbus cloud to the ground.
tornado
T/ F
Tornadoes are not always visible as they are made of
air.
true
scientists who specialize in the study of the atmosphere,
Meteorologists,
very large thunderstorm clouds
supercells
where do violent tornadoes usually come from?
at the base of very large thunderstorm clouds called supercells.
condensation funnels do not touch the ground
funnel clouds.
is characterized by a large mass of storm clouds rotating around a
low-pressure center.
Tropical Cyclone
A tropical cyclone formed in Atlantic or Northeast Pacific Oceans,
hurricane.
If a tropical cyclone is formed over the South Pacific Ocean or the Indian Ocean,
cyclone
a cyclone formed in the Northwest Pacific Ocean,
typhoon.
t/f
Tropical cyclones can form nor cross the equator.
FALSE
WHEN DOES HURRICANES OCCUR?
June to October,
WHEN DOES TYPHOON OCCURS?
May to November,
WHAT KIND OF TROPICAL CYCLONE WE HAVE IN THE PHILIPPINES?
TYPHOON
WHEN DOES CYCLONE OCCUR?
December to April
ON WHAT SPEED SHOULD A TROPICAL CYCLONE HAVE TO BE CALLED A TYPHOON?
118 KILOMERTERS PER HOUR
WHERE DOES Tropical cyclones derive their energy from?
heat, wind, and water cycle processes over the oceans.
T/F
Tropical cyclones can travel over the oceans with greater energy but weaken when they reach land.
TRUE
T/F
As tropical cyclones move to land, they can bring with them violent
winds, storm surges, heavy rains, and floods.
TRUE
is a tropical cyclone that develops over the warm waters of the Northwest Pacific Ocean.
TYPHOON
A typhoon develops in the presence of the following:
- LARGE SPACE OVER AND ABOVE OCEANS
- WATER OCEAN TEM[PERATURE 26 DEGREES CELCIUS
- 46 METERS DEPTH
- WIND REACHER HIGH IN THE ATMOSPHERE
The space left by the rising warm air
low-pressure area,
The center OF THE TYPHOON that may appear to look like a hole
typhoon’s eye.
The eye OF THE TYPHOON is bordered by a thick wall of clouds
called an
eyewall,
swirling clouds around THE EYEWALL that forms the
RAINBANDS
T/F
The typhoon’s eye is the low-pressure area in its center.
TRUE - It is where cool air continuously
sinks into as the warm air around it continuously
WHAT IS TKHE CALMEST PART OF THE TYPHOON?
THE EYE PART
T/F
If you are inside the eye of the typhoon, the winds are VIOLENT and there is HEAVY rain.
FALSE - If you are inside the eye of the typhoon, the winds are gentle and there is no rain.
It is the part of the typhoon with the highest amount of energy; thus, it is where the
winds are strongest and rains are heaviest.
EYEWALL
WHAT PART OF THE TYPHOON PRODUCES THUNDERSTORMS?
RAINBANDS
T/F
rains. Wind speed in rainbands is faster near the center and slower in the outer parts of the band.
TRUE
WHAT Stage of Typhoon Development
a cluster of cumulus clouds shows a weak spiraling movement.
formative stage,
WHAT Stage of Typhoon Development
a cluster of cumulus clouds shows spiraling movement SPEED OF 36 KILOMETERS PER HOUR
tropical depression.
WHAT Stage of Typhoon Development
a cluster of cumulus clouds shows spiraling movement SPEED OF 62 KILOMETERS PER HOUR
tropical storm.
WHAT Stage of Typhoon Development
a cluster of cumulus clouds shows spiraling movement SPEED OF 89 KILOMETERS PER HOUR
severe tropical storm.
WHAT Stage of Typhoon Development
a cluster of cumulus clouds shows spiraling movement SPEED EXCEEDS 118 KILOMETERS PER HOUR
TYPHOON
A tropical cyclone with more than 220 kilometers per hour maximum wind speed is categorized as a
super typhoon.
T/F
Typhoons usually lose their
energy as they move over land where there is less moisture or when they move toward the
poles where the air is colder.
TRUE
T/F
A typhoon is already at its mature stage wherein the eye is formed.
TRUE
A typhoon reaches its decaying stage when its winds STRENGTHEN
FALSE - A typhoon
reaches its decaying stage when its winds weaken as it loses its energy.
WHEN DOES A TYPHOON MAKE A LANDFALL?
A typhoon is said to have made landfall if its eye reaches land.
T/ F it is impossible to observe the changes in the weather if a typhoon is approaching.
false - it is still possible to observe the changes in the weather if a typhoon is approaching.
tell if before, during, after typhoon
the air will feel cold and dry.
before
tell if before, during, after typhoon
Dark clouds forming that can cover the horizon or the whole sky above
are also noticeable.
before typhoon
tell if before, during, after typhoon
typhoon, violent winds and heavy rains can be experienced with possible periods of calm weather in between rainbands.
during typhoon
tell if before, during, after typhoon
When the winds are strongest and the rain is heaviest, the eyewall is passing through your location.
during typhoon
tell if before, during, after typhoon
If you are near the coast, you can notice the big waves slamming on the coastline brought about by the winds.
during the typhoon
tell if before, during, after typhoon
you can expect a calm weather and a clearer sky.
after the typhoon
what are the cause of tropical disturbances in the Philippines?
Cold fronts
Monsoon
Intertropical Convergence Zone (ITCZ)
Easterly Waves
what are easterly waves?
These are the east-to-west flow trade winds.
what is Intertropical Convergence Zone (ITCZ)
exchanges with the wind
coming from the southern hemisphere. and north hemisphere
formed due to the differences in temperature and pressure between the oceans of the continents.
monsoon
are weather disturbances caused by the temperature in the region.
cold fronts
