G8 Science Q2- Week 5- How to track Typhoon.ppt

Science 8 Quarter 2 MELC based PPT

1. HOW TO
TRACK
A TYPHOON ?
PREPARED BY: TYPE YOUR NAME HERE

2. Trace the path of typhoons
that enter the Philippine Area
of Responsibility (PAR) using a
map and tracking data
S8ES -IIf - 21

3. LATITUDE AND LONGITUDE

4. Any location on Earth is described by two
numbers--its latitude and its longitude.
If a captain of a plane wants to specify
position on a map, these are the
“coordinates” they would use.

5. LONGITUDE AND LATITUDE
these are two angles
measured in degrees,
“minutes of arc” and “seconds
of arc”
These are denoted by the
symbol( º, ' , '' )
Example: 35º 43 ' 9 ''

6. LATITUDE
lines that go EAST and WEST
also known as PARALLELS
best known parallel of latitude is
the EQUATOR
the Equator divides the Earth
into two equal parts.
HEMISPHERES

7. LATITUDE
measures distance north and south of the
Equator
numbered 0 to 90 º
As the number of the latitude becomes
higher, the farther it is from the Equator
In writing degrees of latitude, the word
“North” (N) or “SOUTH” (S) is added

8. EXAMPLE
SEATTLE, WASHINGTON
47º NORTH
LIMA, PERU
12º SOUTH

9. LONGITUDE
term used for the lines found in the
east-west direction
beginning line is at GREENWICH
(Great Britain)
PRIME MERIDIAN( 0 º)
In reading reading degrees
longitude, you add “EAST” (E) or
“WEST” (W)

10. LONGITUDE
MERIDIAN is the term used for the lines that
show longitude.
The Meridian of 180 degrees WEST is the
same as that of 180 degress EAST.
•Every meridian must cross the equator.
•since equator is a circle, it'll be divided
into 360 º and the longitude of a point is
then the marked value of a division
where its meridian meets the equator.

16. QUIZ
What is the latitude and
longitude of :
1.MEXICO CITY
2.LOS ANGELES, CALIFORNIA
3.KUALA LUMPUR, MALAYSIA
4.SYDNEY, AUTRALIA
5.MANILA, PHILIPPINES
6.BAGHDAD, IRAQ
7.DUBLIN, IRELAND
8.KAMPALA, UGANDA
9.PORT VILA, VANUATU
10.LIMA, PERU
If it's 8:00 p.m. in the
Philippines, what time is it
in:
1.PARIS, FRANCE
2.TAIWAN
3.NEW YORK, USA
4.JAPAN
5.ARGENTINA

17. The Compass

19. Exercise

20. Plot the coordinates by finding out the
exact square where Rosing is located. For
this exercise, you need the first set of
latitude and longitude - 14.4 north and
125.9 east. Now, look along the borders
of your tracking chart the coordinate
numbers 14 north and 125 east. You must
converge 14 and 125 in one point, which
will be 14.0 and 125.0.

21. 14*
125*

22. 14*
125*

25. Having located the coordinates,
your next task is to pinpoint the
precise location. Calculate 14.4
and 125.9 by dividing the
coordinate box into 10 equal
parts.

27. Let’s continue the tracking
of Typhoon Rosing

28. Start plotting the present storm. For example: Super
Typhoon Rosing (Angela) of November 02, 1995.
