    Study Notes

    Types of Weather

    • Fine weather: clouds and no rain
    • Fair weather: clouds may produce rain, but most of the day is sunny
    • Rainy weather: rain occurs during most of the day
    • Stormy weather: characterized by rain and strong winds

    Weather Instruments

    • Barometer: measures atmospheric pressure
    • Thermometer: measures temperature
    • Hygrometer: measures relative humidity
    • Anemometer or wind vane: measures wind direction and speed
    • Rain gauge: measures precipitation
    • Observation: involves studying clouds, shape, and elevation

    Weather Disturbances

    • El Niño (El Niño de Navidad or Little Boy)
    • La Niña
    • Prevailing wind systems: Monsoons (Amihan and Habagat) and Easterlies

    Disaster Readiness and Risk Reduction

    • Hazard: a process, phenomenon, or human activity that may cause loss of life, injury, or other health impacts, property damage, social and economic disruption, or environmental degradation
    • Disaster: a serious disruption of the functioning of a community or society involving widespread human, material, economic, or environmental losses and impacts that exceed the ability of the affected community or society to cope using its own resources
    • Risk: the likelihood or possibility that an area (or section of population) will be negatively affected by a hazard

    Hazard Types

    • Biological: organic origin or conveyed by biological vectors, including pathogenic microorganisms, toxins, and bioactive substances
    • Environmental: soil degradation, deforestation, loss of biodiversity, salinization, and sea-level rise
    • Geological: earthquakes, volcanic activity and emissions, and related geophysical processes
    • Hydrometeorological: tropical cyclones, floods, drought, heatwaves, and cold spells
    • Technological: industrial pollution, nuclear radiation, toxic wastes, dam failures, transport accidents, factory explosions, and chemical spills

    Earthquakes

    • Types of waves: Body waves (P wave and S wave) and Surface waves (Love Wave and Rayleigh Wave)
    • Magnitude: measures the energy released during an earthquake (Richter Scale)
    • Intensity: measures the damage produced and the reaction of people (Mercalli Intensity Scale)
    • Foreshock, Main shock, and Aftershock

    Philippines-specific Information

    • Annual average rainfall: 965 - 4,064 mm
    • Lowest precipitation levels: Eastern Samar, Surigao, Baguio, and the southern part of Cotabato
    • Annual average temperature: 27°C
    • PAGASA: Philippine Atmospheric, Geophysical, and Astronomical Services Administration
    • PHIVOLCS: Philippine Institute of Volcanology and Seismology
