WMO (World Meteorological Organization) Disaster Risk Reductionactivities are integrated and coordinated with otherinternational, regional and national organizations. WMOcoordinates the efforts of NMHSs to mitigate human and propertylosses through improved forecast services and early warnings, aswell as risk assessments, and to raise public awareness.Natural hazards are severe and extreme weather and climateevents that occur naturally in all parts of the world, although someregions are more vulnerable to certain hazards than others. Naturalhazards become natural disasters when people’s lives andlivelihoods are destroyed. Human and material losses caused bynatural disasters are a major obstacle to sustainable development.By issuing accurate forecasts and warnings in a form that is readilyunderstood and by educating people how to prepare against suchhazards, before they become disasters, lives and property can beprotected. Emphasis is on disaster risk reduction: one dollarinvested in disaster preparedness can prevent seven dollars’ worthof disaster-related economic losses—a considerable return oninvestment. WMO’s objective is to reduce by 50 per cent, by2019, the associated 10-year average fatality of the period 1994-2003 for weather-, climate- and water-related natural disasters.Natural hazards occur across different time and area scales andeach is in some way unique.
Thunderstorms, Lightning, and Tornadoes -Severe thunderstormsgive rise to suddenelectrical discharges inthe form of lightning andthunder. They often bringheavy rain or hail, strongwinds and occasionallysnow. In some parts ofthe world they triggertornadoes.Forest or Wildland Fire -Massive and devastatingfires can be triggeredduring and after periodsof drought, by lightningor by human
Drought - The primary cause of any drought is deficiency of rainfall. Drought is different fromother hazards in that it develops slowly, sometimes over years, and its onset can be masked bya number of factors. Drought can be devastating: water supplies dry up, crops fail togrow, animals die and malnutrition and ill health become widespread.Tropical cyclones - WMO provides assistance to Members in establishing national and regionallycoordinated systems which ensure that the loss of life and damage caused by tropical cyclonesare reduced to a minimum. Tropical cyclones are areas of very low atmospheric pressure overtropical and sub-tropical waters which build up into a huge, circulating mass of wind andthunderstorms up to hundreds of kilometres across. Surface winds can reach speeds of 200km/h or more. The combination of wind-driven waves and the low-pressure of a tropical cyclonecan produce a coastal storm surge—a huge volume of water driven ashore at high speed and ofimmense force that can wash away everything in its path.Desert locusts - Desert locusts inflict damage in Africa, the Middle East, Asia and southernEurope. When weather and ecological conditions favour breeding, the insects are forced into asmall area. They stop acting as individuals and start acting as a group.Floods and flash floods - Floods can occur anywhere after heavy rain events. All floodplains arevulnerable and heavy storms can cause flash flooding in any part of the world. Flash floods canalso occur after a period of drought when heavy rain falls onto very dry, hard ground that thewater cannot penetrate.Landslide or mudslide (mudflow) - Mudslides and landslides are local events and usuallyunexpected. They occur when heavy rain or rapid snow or ice melt or an overflowing crater lakesends large amounts of earth, rock, sand or mud flowing swiftly down mountainslopes, especially if these are bare or burnt by forest or brush fires.
