Study Notes
Air Masses and Fronts
- Air masses are large bodies of air, often spanning thousands of miles, with uniform temperature and moisture characteristics.
- The source region is where an air mass develops its specific temperature and moisture properties.
- Air masses can be categorized as cold or warm based on temperature and dry or moist based on humidity.
- Polar air masses (P) form over ice caps and are very cold.
- Tropical air masses (T) form in lower latitudes and are generally warm.
- Continental air masses (c) originate over land and are typically dry.
- Maritime air masses (m) form over large bodies of water and are moist.
Types of Air Masses
- Continental Polar (cP): Cold and dry, forming over polar landmasses, bringing clear skies and cold weather.
- Continental Tropical (cT): Hot and dry, forming over desert regions, leading to heat waves and droughts.
- Maritime Polar (mP): Cold and humid, forming over polar oceans, causing damp weather, fog, and drizzle.
- Maritime Tropical (mT): Warm and humid, forming over tropical oceans, bringing heavy rainfall and high humidity.
Weather Fronts
- Different air masses interact, causing weather changes when they move over land.
Typhoons
- Typhoons are intense, round storms with revolving winds reaching speeds of up to 120 km/h.
- Typhoons cause significant damage through landslides, flooding, and storm surges.
- They develop over warm ocean waters and intensify due to heat and moisture.
- The Philippines, situated in the Pacific Typhoon Belt, experiences an average of 20 typhoons annually, with five potentially destructive.
- The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) assigns Filipino names to typhoons entering the Philippine Area of Responsibility (PAR) since 1963.
- A campaign called "Name A Bagyo" in 1998 allowed the public to suggest typhoon names.
- PAGASA uses a list of 140 names, grouped into four categories of 25 names each (A-Z), with auxiliary names used if all are used.
Cyclones, Storms, and Typhoons' Impact Mitigation
- Mitigation aims to prevent or reduce the negative consequences of cyclones, storms, and typhoons.
- Environmental protection: Preserving mangroves and costal forests to buffer against storm surges and coastal erosion. Protecting coral reefs to dissipate wave energy, protect coastal areas from damage, and replenish beach sand.
- Climate change Mitigation: Reducing greenhouse gas emissions by transitioning to renewable energy sources (Solar, Wind, Geothermal, Hydropower). Engaging communities in education and awareness campaigns regarding cyclones and disaster preparedness.
- Evacuation plans: Implementing detailed evacuation routes with clear signages, conducting drills, and rehearsals to ensure public readiness.
- Land use planning: Identifying flood-prone areas, enforcing building codes for weather-resistant structures, and maintaining setback zones along coastlines and floodplains.
- Early warning systems: Utilizing satellites and weather radars for early typhoon detection, allowing authorities to issue warnings through SMS, loudspeakers, or radios to inform communities.
Light, Color, and Atmospheric Optics
- The interaction of light with objects defines color.
- The visible light spectrum is the portion of the electromagnetic spectrum that humans can see.
- Red, green, and blue are primary colors of light, capable of producing all other colors when combined in equal intensity.
Rainbows
- Rainbows illustrate the principles of optics, including refraction, dispersion, and wavelength differences.
- Their appearance signals the cessation or decrease of rain, as they form when sunlight shines through lingering moisture.
- Climate change is projected to increase rainfall visibility, leading to a 5% higher frequency of rainbows by 2100.
- This trend is more prominent in higher latitudes and altitudes but less noticeable in drier regions.
Cultural and Symbolic Importance of Rainbows
- Rainbows are associated with hope, unity, and restoration in many cultures.
- Often appearing after storms, they symbolize rebirth.
- They are viewed as bridges or passages to other realms in various mythologies and as symbols of covenants in Christianity.
