Q4 W2 Hydrometeorological and Coastal Hazards

• hydrometeorological


  A 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
• coastal hazards


  Hazards that occur in coastal areas
• Typhoon

  • A low-pressure area, or a wide and violent tropical cyclone. It rotates in the counterclockwise direction, with warm air rising above Western Pacific Ocean warm water
• Flood

  • Characterized as superfluous water that swamps normally dry land and properties
• La Nina

  • Represents periods of under-average sea surface temperatures across the Equatorial Pacific in the east-central
• Storm surge

  An abnormal rise in sea level during tropical cyclones or "bagyo"
• Thunderstorm

  • A local storm created by cumulonimbus clouds and are often accompanied by lightning and thunder, usually with strong wind gusts, heavy rain and occasionally hail and/or tornado

  
• El Nino

  • Refers to the large-scale ocean-atmosphere climate interaction linked to a regular warming of sea surface temperatures around the Equatorial Pacific region and east center
• Flashflood

  • Often caused by heavy rainfall in a short time span, typically less than 6 hours
• Hydrometeorological Hazards


  • Typhoon
  • Thunderstorm
  • Flood
  • Flash Flood
  • Storm Surge
  • El Niño
  • La Niña
• Thunderstorm


  • Powerful, short-lived weather disturbance, almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and fast, roaring winds
  • Occurs when layers of dry, moist air rise to cooler regions of the atmosphere in a broad, rapid updraft
• Thunderstorm Stages


  1. Cumulus Stage

  2. Mature Stage

  3. Dissipating Stage
• Flood


  A high-water stage in which water overflows its natural or artificial banks onto normally dry land
• Flash Flood


  • Caused by heavy rain or the sudden release of water over a short period of time
  • The name "flash" refers to their fast occurrence and also to their raging torrents of water that move with great speed
• Storm Surge


  "Daluyong ng Bagyo" in the Philippine system where the irregular sea-level rise during tropical cyclone or "bagyo" occurs
• El Niño


  Refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific
• La Niña


  Episodes represent periods of below-average sea surface temperatures across the east-central Equatorial Pacific
