Study Notes
Tropical Cyclone
- A collective term for storms that originate in warm tropical oceans
- Includes Typhoons, Hurricanes, and Cyclones
Typhoon vs Hurricane vs Cyclone
- All refer to the same phenomenon, but names vary by location
- Typhoon: Northwest Pacific
- Hurricane: North Atlantic and Central/Eastern Pacific
- Cyclone: South Pacific and Indian Ocean
Typhoon Characteristics
- Eye: Calm winds and clear weather
- Eyewall: Maximum wind zone, characterized by heavy rain and thunderstorms
- Rainbands: Spiraling, curved bands of clouds and thunderstorms, extending outwards from eyewall
Conditions for Typhoon Formation
- Continuous evaporation and water cycles
- Differences in air pressure
- Convergent Winds
Conditions for Typhoon Formation: Continuous Evaporation and Water Cycle
- Heat drives water evaporation
- Saturated clouds become heavy with moisture, resulting in rain
Conditions for Typhoon Formation: Differences in Air Pressure
- Meteorologists monitor air pressure changes
- Increased air pressure: High-pressure area (HPA)
- Reduced air pressure: Low-pressure area (LPA)
- HPA and LPA differences create winds
Conditions for Typhoon Formation: Convergent Winds
- High-speed winds in a specific area
- Created by differences between HPA and LPA
Instruments Used to Monitor Weather
- Anemometer: Measures wind speed
- Wind Vane: Shows wind direction
- Thermometer: Measures air temperature
- Rain Gauge: Collects and measures rainfall over time
- Barometer: Measures air pressure
The Philippines and Typhoons
- Located within the Pacific typhoon belt
- Located within the Intertropical Convergence Zone (ITCZ)
- ITCZ: Where northern and southern winds converge
- ITCZ is a breeding ground for typhoons
Recent Rainfall Patterns in the Philippines
- Significant increase in rainfall due to the habagat wind
- Impacts need to be addressed by authorities.
