hydrometeorological hazards

water

hydro means

meteorological

concerned with the process or phenomena of the atmosphere especially as means of forecasting weather

hydrometeorological hazards

are processes or phenomena of atmospheric, hydrological or oceanographic nature

• loss of life

• injury

• property damages

• loss of livelihood

• environmental damages

damages a hydrometeorological hazard could cause (5)

national oceanic and atmospheric administration

NOAA means

• tropical cyclones

• typhoon

• thunderstorm

• tornado

• flash flood

• el niño and la niña

hydrometeorological hazards includes (6)

cyclone

• an intense low pressure system which is characterized by strong spiral winds towards the center called the eye in a counter-clockwise flow

• a term commonly used in when the storm forms in the south pacific or indian ocean

• strong winds with heavy rainfall

• storm surges

• landslides

• mudflow

hazards due to cyclone (4)

• tropical depression

• tropical storm

• typhoon

classification of cyclones (3)

tropical depression

a classification of cyclone where maximum winds can reach up to 35kph to 63kph

tropical storm

a classification of cyclone where maximum winds can reach up to 64kph to 118kph

typhoon

a classification of cyclone where maximum winds exceeds 118kph

typhoon

• is a large, powerful, and violent tropical cyclone with a low pressure area rotating counter-clockwise and contains warm air

• a term commonly used in when the storm forms in the northwest pacific

satellite

• is the most advanced technology used in monitoring a cyclone or typhoon

• it can visualize exactly in real time formation and path of a cyclone

doppler radar

• is an acronym for radio detection and ranging

• it measures the speed of moving objects such as precipitation and has capacity to measure the velocity of the particles in order to determine the rate

radio detection and ranging

RDR means

• bounces sound waves off the storm clouds

• can tell if raindrops are moving toward or away from observers

• can spot spinning movements in clouds which helps scientist to predict which way storm will travel

how does a doppler works?

thunderstorm

is a weather condition that produces lightning and thunder, heavy rainfall form cumulonimbus clouds, and possibly tornado

cumulonimbus clouds

cloud that is filled with rain

lightning

this is hotter than the surface of the sun and can reach temperatures around 50,000 fahrenheit

50,000 fahreinheit

temperature a lightning can reach

1. crouch down low like a baseball catcher, get as low as you can, the nearer you are to the ground, the less likely you are to be struck by lightning, but never lay down

2. if your hair begins to stand on end or your skin starts to tingle, a lighting strike is imminent, immediately get into the crouching position, lighting may strike without this warning

3. place hands over ears to minimize hearing loss from the loud clap of thunder that will boom very close to you

4. don’t touch any possible conductors

5. the only thing touching the ground should be the balls of your feet, lightning can hit the ground first, and then enter your body, the more you minimize your contact with the ground, the less chance of electricity entering your body

6. touch the heels of your feet together, if electricity from a ground strike enters through your feet, this increases the chances of the electricity going in one foot and out the other, rather than into the rest of your body

how to survive lightning strike

tornado

• described as a violent rotating column of air extending from thunderstorm to the ground

• typically in the form of a visible condensation-funnel which is narrow and touches the earth

flashflood

rapid flooding of geomorphic low-lying areas

• heavy rain

• tropical storm

• typhoon

common cause of flash flood (3)

intensity

rate of rainfall

duration

how long the rain last

el niño / la niña

• are complex weather patterns resulting from variations in ocean temperature

• these two phenomena are opposite phases of what is known as ENSO cycle

• typically last 9-12 months but some prolonged events may last years

el niño-southern oscillation

ENSO means

ENSO cycle

is a scientific term where sea surface temperature flunctuates between warm phases (el niño) and cool phases (la niña) every few years

project noah

• a project for scientific forecasting, monitoring, assessment and information services regarding natural hazards

• more accurate, integrated and responsive disaster prevention, and mitigation system, especially in high-risk areas throughout the Philippines

• the project will harness technologies and management services for disaster risk reduction activities offered by the DOST through PAGASA, PHILVOLCS

• distribution of hydrometeorological devices in hard-hit areas

• disaster risk exposure assessment for mitigation

• enhancing geohazards mapping

• CHASSAM

• floodNET

• LaDDeRS

• landslide sensors development project

• WHIP
