Hydro-Meteorological Hazards (DRRR)

• HYDRO-METEOROLOGICAL HAZARDS are NATURAL HAZARDS
• Typhoon


  Weather system with 2-300 km radius, characterized by strong winds, heavy rainfall, and storm surge
• Thunderstorm


  • Characterized by lightning, thunder, heavy rain, strong winds, and hail
• Flood


  Excess water inundating typically dry land, causing disruption and damage to people, property, and agriculture
• Storm Surge


  Temporary rise in sea level along a coast caused by low pressure and strong winds
• El Niño


  Disrupts usual circulation patterns, causing ocean warming, weakened trade winds, and global teleconnections
• La Niña


  Disrupts usual circulation patterns, causing ocean cooling, stronger trade winds, and global teleconnections
• Tornado


  Column of violently turning air that touches the ground, typically attached to a thunderstorm
• Project NOAH is the Philippines' primary disaster risk reduction program utilizing science and technology to provide hazard information and early warnings
• A mature typhoon can be broken down into three main parts: Eye, Eyewall, and spiral rainbands.
• Eye: This is the calm and clear center of the storm. It typically has a diameter ranging from 10 to 60 kilometers (6 to 37 miles), and can sometimes even reach 200 kilometers (124 miles) across! The air pressure here is the lowest in the entire storm system, and there are typically light winds and clear skies.
• Surrounding the eye is the eyewall, a ring of towering thunderstorms with the most intense winds and heaviest rainfall. This is the most destructive part of the typhoon, with wind speeds reaching up to 300 kilometers per hour (186 miles per hour) or even higher.
• Extending outward from the eyewall are spiral rainbands, containing intense thunderstorms that produce heavy rain. These bands rotate around the eyewall and contribute to the overall size and wind field of the typhoon. The farther you move away from the eyewall, the weaker the winds and rain become.
