4. The Sun shines more directly near the
equator bringing these areas more
warmth. However, the polar regions
are at such an angle to the Sun that
they get is little or no sunlight during
the winter, causing colder
temperatures. These differences in
temperature create a restless
movement of air and water in great
swirling currents to distribute heat
energy from the Sun across the
planet.
Introduction

5. When air in one region is
warmer than the surrounding
air, it becomes less dense and
begins to rise, drawing more
air in underneath. Elsewhere,
cooler denser air sinks,
pushing air outward to flow
along the surface and
complete the cycle.

6. What is WEATHER?
• the hour to hour, day to day
change in the atmosphere.

7. What is CLIMATE?
• the average weather conditions
of a place taken over a long
time.

8. > The difference between
weather and climate is a
measure of time.

9. How do we measure
weather?

Precipitation
Measuring a Weather

10. Cloud cover
> Cloud cover is measured
just by using our eyes.

11. Cumulus Clouds
are the puffy clouds that look like puffs of
cotton. Cumulus clouds that do not get very tall
are indicators of fair weather. If they do grow
tall, they can turn into thunderstorms. The
bottom of cumulus clouds are fairly close to the
ground.

12. Status Clouds
look like flat sheets of clouds. These clouds can
mean an overcast day or steady rain. They may
stay in one place for several days.

13. Cirrus Clouds
are high feathery clouds.
They are up so high they are
actually made of ice
particles. They are indicators
of fair weather when they
are scattered in a clear blue
sky.

14. TEMPERATURE
> is measured using
maximum - minimum
thermometers

15. A WEATHER THERMOMETER

16. SUNSHINE
> The total amount of sunshine in
a day is measured using a sunshine
recorder.

17. Camp-Strokes Sunshine Recorder
The sun’s rays travel through the
glass ball and burn marks onto the
card behind it.

18. AIR PRESSURE
> Air pressure is
measured using a
barometer and recorded
using a barograph .

19. Barometer

20. Precipitation
> Precipitation is any
moisture that comes from the
atmosphere
(rain, snow, hail).

21. RAIN GUAGE
The amount of
precipitation is measured using a
rain gauge .

22. WIND
Wind is measured in two ways
with two instruments:
– Wind Vane
– Anemometer

23. Wind Vane
Wind Direction

24. Anemometer
Wind Speed

26. TROPICAL CYCLONE
A Tropical Cyclone (known as
“Bagyo” in the Philippines) is the
global generic term for an intense
circulating weather system over
tropical seas and oceans.
Tropical Cyclone

27. TOPICAL CYCLONE CATEGORY
There are four (4) classifications of
tropical cyclone based mainly on its
strength or maximum sustained winds
(based on 1-minute or 10-minute
average):
*Tropical Depression
*Tropical Storm
*Typhoon
*Super Typhoon

28. *Tropical Depression
-Have a maximum
sustained winds of
between 35 KPH
and 64 KPH near
the center

29. *Tropical Storm
- Have a maximum
sustained winds of
between 65 KPH
and 118 KPH near
the center

30. *Typhoon
-Have a maximum
sustained winds of
between 19 to 200
KPH near the
center

31. *Super Typhoon
-Have a maximum
sustained winds
greater than 200
KPH

32. PUBLIC STORM WARNING

be expected in at least 36 hours or
intermittent rains may be expected
within 36 hours.
>>twigs and branches of small trees
may be broken .

33. PUBLIC STORM WARNING
SIGNALS
Signal #2

and up to 100 kph may be expected
in at least 24 hours
>>Some coconut trees may be tilted
with few others broken . Few big
trees may be uprooted.

34. Signal #3

kph up to 185 kph may be expected
in at least 18 hours.

houses may be unroofed or
destroyed and there may be
considerable damage to structures
of light to medium construction.

SIGNALS

35. PUBLIC STORM WARNING
SIGNALS
Signal #4
>>It has a very strong winds of more
than185 kph may be expected in at
least 12 hours

buildings of mixed construction may
be severely damaged

36. QUOTATION:
“Climate is what you
expect; Weather is what
you get."
