hydrometeorological hazards

1. HYDROMETEOROLOGICAL
HAZARDS

2. What is hydrometeorological hazards?
Process or phenomenon of atmospheric,
hydrological or oceanographic nature that
may cause loss of life, injury or other health
impacts, property damage, loss of livelihoods
and services, social and economic disruption,
or environmental damage.

3. Describe the different hazards that you might
experience in the occurrence of the following:
typhoon
monsoon
ipo-ipo
flood

4. What is typhoon?

10. HAZARDS DUE TO TROPICAL CYCLONES (includes tropical
depressions, tropical storms and hurricanes)
Storm surge
Floods
Heavy rains
Destructive winds
High surf and rip currents

11. Monsoon
 Is a seasonal changes in atmospheric circulation and precipitation
associated with annual latitudinal oscillation of the Intertropical
Convergence Zone (ITCZ)
 Usually the term monsoon is used to refer to the rainy phase of the
seasonally changing pattern, although technically there is also a dry
phase
 It is caused by seasonal shift in the winds
The winds shift because the temperature of the water are different as
seasons change.

12. HAZARDS DUE TO MONSOON
Summer monsoon can bring heavy rains that
destroy homes, damage infrastructure, wash
away crops and destroy water, sanitation and
hygiene infrastructures.
During winter monsoon, dry weather can lead to
drought and crop failures from lack of moistures.

13. What is the importance
of knowing the hazards
in your community?

18. Explain the phrase
"LIGTAS ANG MAY
ALAM"

19. Although
hydrometeorological
events are
unavoidable, we
sought to reduce the
loss of life and
property during a
natural disaster.
Moreover, one way of
reducing it is being
prepared and informed of
the measures to take.
Actions conducted in
advance of the event and
additional activities carried
out during and immediately
after the event are all part
of preparation.

20. Hazard maps are useful for
raising risk awareness,
planning evacuation protocols,
and choosing where evacuation
facilities and shelters should be
located.

21. HAZARD MAP
HAZARD MAP highlights areas affected by or is
vulnerable to a particular hazard— normally
created for natural hazards, such as
earthquakes, volcanoes, landslides, flooding, and
tsunamis.
Hazard maps are easy to understand and easy to
use for purposes of prompt evacuation, and
users should be aware of the limitations and
uncertainties of the information they contain.

22. HAZARD MAP
Hazard maps help prevent serious damage and
deaths. It comes in different forms:
Typhoon Incidence Map, Rainfall Map, Risk to
Projected Rainfall Change, Rainfall Projected
Change (Dry Season) Temperature Increase Map,
Monsoon Map, and Historical Rainfall Map.

23. COASTAL PROCESSES
are inevitable occurrences
driven by nature and amplified
by human action.

24. COASTAL PROCESSES INCLUDES:
Waves
 tides
storm surge
rising sea level
and crustal movement
Coastal erosion, submersion, and saltwater intrusion all
cause harm to shorelines.
