12. Can you differentiate
weather from a
climate?

13. Weather is what
conditions of
the atmosphere
are over a short
period of time.

14. Climate is how
the atmosphere
"behaves" over
relatively long
periods of time.

15. Activity 1. Read the
article about typhoon
Ulysses and answer
the questions that
follow

16. Typhoon Ulysses: Weather updates in the
Philippines.
Typhoon Ulysses (Vamco), the Philippines' 21st
tropical cyclone for 2020, hit Luzon hardest
from November 11 to 12.The typhoon
unleashed powerful winds and 2 torrential rain
that killed dozens of people, destroyed
thousands of homes, and left areas of the
island region flooded.

18. What are the types of weather disturbances?
Look at the following pictures of weather
disturbances?

20. 1. What are the characteristics of storm?
2.What are the most common types of
weather disturbance?
3. Where does a hurricane form?
4.Why it is considered the most violent
storms on Earth?

22. Complete the concept map.

23. Weather disturbances refer to any disruption
to the atmosphere’s stable condition. It can
manifest through the formation of low
pressure area or prevailing winds like
monsoons and the Intertropical Convergence
Zone or ITCZ.

24. Storm is a violent
disturbance in atmosphere
marked by sudden changes
in air pressure and rapid air
movements.

26. A.Tropical Cyclone-is a low-
pressure area that forms in
the tropics over the seas and
oceans. The terms cyclone,
typhoon, and hurricane
means the same.The name
only varies according to its
location.

27. Cyclones are formed over
the South Pacific and
Indian Ocean. Typhoons
are formed over the
Northwest Pacific Ocean.
Hurricanes are tropical
storms that formed over
the North Atlantic Ocean
and Northeast Pacific.

28. Classifications of Tropical Cyclones
• Tropical depression- has a
maxium sustained wind
speed of less than 63km/hr.
• Tropical storm-the winds
have a maximum sustained
wind speed which range
from 63 to 118km. /hr.
• Typhoon-the maximum wind
speed is greater than
118km/hr.

29. B.Thunderstorms- is a
storm characterized
by strong winds,
short- period heavy
rains that generally
last for one to two
hours, with lightning
and thunder.

30. C.Tornado-is a
funnel-like or
roped shaped
cloud with a
diameter of less
than 400 meters.

32. Other Weather
Disturbances in the
Philippines

33. A. Monsoons-is a continuous
change in the direction of the
prevailing winds blowing at a
particular direction. Our country
experiences two distinct monsoons,
the northeast and the southwest
monsoons.

34. 1.Northeast Monsoon
or Hanging Amihan-is
a seasonal wind that
blows from November
to February. It gives us
cold temperatures
during the year.

35. 2.Southwest Monsoon
or Hanging Habagat- The
country experiences this
seasonal wind from May
to October. It is moist,
warm and brings large
amounts of rainfall to
the Philippines

36. B. Easterly Winds
The northeast trade
winds may move
over an elongated
low-pressure area,
forming an easterly
wind.

37. High Pressure Area (HPA) -
air presses downwards,
causing the air on the
surface to be dry, this
indicates a fair weather.
Low
Pressure
Area (LPA)-
warm air
rises, cools
down and
condenses
into clouds.

38. C.Intertropical
Convergenze Zone (ITZC)-
is the area near the
equator where the trade
winds from North and
South Hemisphere meet.
The two trade winds
create a band of clouds
that bring heavy rainfall.

39. A.Directions: Choose the type of weather disturbance
inside the box and write your answer before each
number.
tornado tropical cyclone storm
hurricane thunderstorm monsoons
southwest monsoon northeast monsoon
ITCZ weather disturbance

40. _________1.A violent disturbance in atmosphere marked
by sudden changes in air pressure and rapid air
movements.
_________ 2.The area near the equator where the trade
winds from North and South Hemisphere meet.
________ 3.A low-pressure area that forms in the tropics
over the seas and oceans.
________ 4. A seasonal wind that blows from November
to February.
________ 5.Funnel-like or roped shaped cloud with a
diameter of less than 400 meters.

41. ________6.The country experiences this seasonal wind from
May to October.
________7.Any disruption to the atmosphere’s stable
condition.
________8. Tropical storms that formed over the North
Atlantic Ocean and Northeast Pacific.
________9. A continuous change in the direction of the
prevailing winds blowing at a particular direction.
________10. A storm characterized by strong winds, short
period of heavy rains that last for one to two hours with
lightning and thunder.
