Study Notes
Thunderstorms vs. Typhoons
- Thunderstorms are localized weather events, while typhoons are large, organized systems originating over warm ocean waters.
- Formation of thunderstorms is triggered by atmospheric instability, lifting mechanisms, and moisture.
Lightning and Thunder
- Lightning occurs within clouds due to the separation of electrical charges, while thunder results from the rapid expansion of heated air.
- Both phenomena typically manifest in the lower portions of clouds where charge differences are greatest.
Floods
- A primary characteristic of floods is the overflow of water onto normally dry land.
- Densely populated areas are prone to flooding due to impermeable surfaces like concrete that prevent water absorption.
Human Activities and Flooding
- Urban development, deforestation, and improper drainage systems can exacerbate flooding.
- Preparing waterways by clearing debris and ensuring proper drainage helps mitigate flood risks before storms.
Storm Safety
- Avoid open or isolated areas during a storm to reduce exposure to lightning and strong winds.
- When evacuating, bring essential items like identification, medications, and non-perishable food.
- Electronics should be unplugged during storms to prevent damage from power surges and lightning strikes.
Post-Storm Actions
- After a storm, assess damage carefully and check for hazards like downed power lines.
- Reporting damaged utility wires to authorities prevents accidents and supports safety measures.
Weather Observation
- Observing the direction of cloud movement can indicate storm progression and potential impacts.
- An essential part of a 72-hour survival kit includes food, water, flashlight, battery-powered radio, and first aid supplies.
Household Preparedness
- Meeting with household members before a hydrometeorological hazard ensures everyone understands safety plans.
- Reinforcing the house might involve securing windows and doors to withstand strong winds.
Valuables and Natural Behaviors
- Transferring valuables to higher ground protects them from impending flood damage.
- Some animals have natural instincts that can signal oncoming storms or weather changes.
Natural Events and Cyclones
- Natural events in the oceans and atmosphere are referred to as hydrometeorological events.
- The area near the equator where trade winds converge is known as the Intertropical Convergence Zone (ITCZ).
Tropical Cyclones
- Tropical cyclones typically originate in warm ocean waters; they form where water temperatures exceed approximately 26 degrees Celsius.
- The global phenomenon affecting cyclone formation is called the El Niño-Southern Oscillation (ENSO).
Wind Exchange in Cyclones
- The exchange of winds that contributes to the swirling motion of cyclones is known as the Coriolis effect.
- The Philippines is prone to cyclones and typhoons due to its geographical location and warm ocean currents.
La Niña and El Niño
- La Niña is characterized by cooler ocean temperatures in the central Pacific, promoting higher storm activity in the region.
- During El Niño, the eastern Pacific often experiences warmer atmospheric temperatures.
- Cyclones during La Niña typically bring increased rainfall and severe weather to certain regions of the Pacific.
Common Features of ENSO Phenomena
- Both El Niño and La Niña share the common feature of altering weather patterns globally.
Geography and Atmospheric Hazards
- Elevated areas and knowledge of geographical directions assist in navigating during atmospheric hazards, enhancing safety and evacuation strategies.
