Hydrometeorological Hazards and Disasters (Identification) Flashcards
It is a process or phenomenon of atmospheric, hydrological, or oceanographic nature that may cause loss of life, injury or other health impacts
HYDROMETEOROLOGICAL HAZARDS
- translates from Spanish as “the boy-child”
-
associated with having no rain, hence the fear or drought and
consequently dried-ups and low water levels in dams and
reservoirs for domestic, agricultural, and industrial uses
EL NINO
- translates as “girl-child”
- associated with heavy rainfall and hazards such as flood.
LA NINA
- It is an intense low-pressure system with a minimum sustained wind velocity of 35 kilometers per hour
- has an eye and an eye wall
Tropical Cyclones
usually affect low-lying and coastal areas. This is due to the
overflowing of water from lakes, streams, and other bodies of water
FLOODS
caused by the overflowing of rivers when the run-off exceeds
the capacity of the channels.
River Flood
caused by a very short period of unusually heavy rainfall
Flash Flood
occurs when strong onshore winds push the water inland
Coastal Flood
It is a sudden rise of sea level above the normal level on the coast due to a drop in atmospheric pressure and the force of the wind as a tropical cyclone approaches the coast.
STORM SURGE
It is a localized storm cloud that produces lightning and thunder, and often brings heavy rain shower or hail as well as strong gusty winds
THUNDERSTORM
This is the most dangerous hazard associated with thunderstorm, is a visible electrical discharge due to high voltage differences that build up within the clouds, between the clouds, and the ground.
LIGHTNING
These are ice crystals falling from a thunderstorm. It is therefore not very dangerous but they can destroy crops
HAILSTONES
- It is localized windstorm characterized by a visible funnel-shaped, rapidly whirling cloud extending downward from the base of dark cumulonimbus cloud.
- In the Philippines, it is called _____
TORNADO
- buhawi or ipo-ipo
When a tornado occurs or moves over a body of water, this is called?
WATERSPOUT
is the lack of rainfall for normal needs. Because of the deficiency of rainfall for a long period, the soil moisture is reduced below the minimum necessary to sustain plants, animals, and humans.
DROUGHT
