DRRR

• Hydrometeorological hazard


  Process or phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, injury or other health impacts
• Different hydrometeorological hazards


  • Tropical Cyclones
  • Thunderstorm
  • Hailstorm
  • Tornados
  • Blizzards
  • Heavy Snowfall
  • Avalanches
  • Coastal Storm Surge
  • Floods
  • Drought
  • Heatwaves
  • Cold spells
• Hydrometeorological hazard factors


  • Landslides
  • WildFires
  • Locust Plagues
  • Epidemics
  • Transport and dispersal of toxic substances
  • Volcanic Eruption Material
• Typhoons


  Also called as bagyo, enters the Philippine Area of Responsibility (PAR)
• PAR


  Agency that raises storm signal warnings
• Storm warning signals


  • SIGNAL 1 - Wind of 30 - 61 km per hr, expected to occur in 36 hrs
  • SIGNAL 5 - Wind of 220 km per hr, expected to occur in 12 hrs
• Storm signals


  • Raised when a tropical cyclone is about to hit an area
  • The nearer it gets, the stronger it becomes, storm signals are raised
  • The farther, the weaker, storm signals are downgraded
• Thunderstorm


  A storm with lightning and thunder, forms when air in the lowest layers of the atmosphere rises, produces Cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail
• Thunderstorm formation


  • Moisture
  • Unstable air
  • Lift
• Types of thunderstorms


  • Single cell - small, weak and isolated storms
  • Multi cells - includes cluster of thunderstorms
  • Squall line - collections of storms that can form a line a hundreds of miles long
  • Supercells - most intense kind of storm capable of producing tornadoes
• Updraft


  Air that causes water to evaporate

  Raised when a tropical cyclone is about to hit an area, the nearer it gets, the stronger it becomes, the farther, the weaker, storm signals are downgraded
• Downdraft


  Pulls moisture downward causing rains
• Thunderstorm


  A storm with lightning and thunder, forms when air in the lowest layers of the atmosphere rises, produces Cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail
• Thunderstorm


  • Moisture, unstable air and lift = thunderstorm
• Lightning


  Occurrence of natural electrical discharge of very short duration and high voltage in between a cloud and the ground
• Types of thunderstorms


  • single cell - small, weak and isolated storms
  • multi cells includes cluster of thunderstorms
  • squall line - collections of storms that can form a line a hundreds of miles long
  • supercells - most intense kind of storm capable of producing tornadoes
• Updraft


  An air that causes water to evaporate
• Flash floods


  Rapid flooding or geomorphic low, maybe caused of heavy rains caused by thunderstorm, hurricane, tropical storm or melt water
• Downdraft


  Pulls moisture downward causing rains
• Storm surge


  Abnormal rise of ocean generated by a weather disturbance
• Lightning


  Occurrence of natural electrical discharge of very short duration and high voltage in between a cloud and the ground
• Flash floods


  Rapid flooding or geomorphic low, maybe caused of heavy rains caused by thunderstorm, hurricane, tropical storm or melt water
• Storm surge


  Abnormal rise of ocean generated by a weather disturbance
• El Niño


  Anomaly happens with irregular interval of two to seven years and last for 9 months to 2 years
• El Niño


  Anomaly happens with irregular interval of two to seven years and last for 9 months to 2 years
• La Niña


  Increases the chances of hurricanes, occur when east moving trade winds go into overdrive, straightening a process called upwelling
• Upwelling


  When water is drawn up to the surface which results in cooler than usual
