🌍 1. What is Climate?

Climate is the average weather conditions in a region over a long period of time—typically 30 years or more. It includes patterns in temperature, humidity, wind, and precipitation.

📌 Example: “It’s always rainy in Baguio during June” = climate.
📌 “It rained yesterday” = weather.

🌦 2. Climate vs. Weather

Aspect

Climate

Weather

Definition

Long-term average of atmospheric conditions

Short-term atmospheric changes

Time Frame

30+ years

Minutes to days

Predictability

More stable

Highly variable

Examples

Tropical monsoon climate in the Philippines

Rainstorm in Quezon City on May 15

✔ In your quiz, you correctly distinguished between weather and climate using real-life examples like PAGASA heat index alerts (weather) and rainfall patterns over 30 years (climate).

🌡 3. Elements of Climate

  1. Temperature

  2. Humidity

  3. Precipitation (Rainfall)

  4. Air Pressure

  5. Wind

  6. Cloud Cover

These elements interact to produce different climates across the globe.

🇵🇭 4. Climate in the Philippines

The Philippines has a tropical monsoon climate:

  • Hot, humid summers

  • Heavy rains from June to November (Habagat or Southwest Monsoon)

  • Drier months from December to May (Amihan or Northeast Monsoon)

🗺 5. Types of Climate Zones

Climate Zone

Characteristics

Examples

Tropical

Hot and humid, near equator

Philippines, Brazil, Indonesia

Temperate

4 seasons, moderate temps

USA, Europe, parts of China

Polar

Cold year-round

Antarctica, Greenland

Arid/Desert

Low rainfall, high temps in day, cold at night

Sahara, Middle East

Mediterranean

Mild, wet winters and hot, dry summers

Italy, Greece, California

🌐 6. Factors Affecting Climate

Let’s go deeper into the six primary climate influencers. Each one changes how heat, air, and moisture behave.

6.1. Latitude (Distance from the Equator)

  • Places near the equator receive more direct sunlight → warmer climates.

  • Places farther away (higher latitudes) → colder climates.

🧠 Mnemonic: “Latitude = Attitude of the Sunlight”
🔍 Quiz: Australia is warmer than Greenland because it is closer to the equator.

6.2. Altitude (Elevation)

  • Higher altitude = lower temperature.

  • Air is thinner, holds less heat.

Example: Baguio City (1400m) is colder than Manila (sea level) even though they are at the same latitude.

🔍 Quiz: Iloilo City is warmest among cities at various altitudes.

6.3. Distance from the Sea

  • Coastal areas have moderate climates due to water’s slow heating and cooling.

  • Inland areas experience more temperature extremes.

🔍 Quiz: City A (coastal) = stable temps; City B (inland) = big changes.

6.4. Ocean Currents

  • Warm currents → warm air → wet and mild coasts.

  • Cold currents → cool air → dry climates.

Current

Effect

Example

Gulf Stream

Warms the East USA

Coral reefs flourish

Peru (Humboldt)

Cools West South America

Dry desert in Chile & Peru

🔍 Quiz: Humboldt current = cooler, drier climate

6.5. Wind Systems

  • Prevailing winds move air masses and moisture.

  • Warm air → rises → low pressure

  • Cold air → sinks → high pressure

🔍 Quiz: Warm air rising = low pressure (not high!)

6.6. Topography (Relief)

  • Mountains affect rainfall:

    • Windward side = moist, rainy

    • Leeward side = dry (rain shadow)

🔍 Quiz: Point B is leeward = dry and little rainfall

📊 7. Climate Diagrams: Temperature, Rainfall, Humidity

Understanding climographs is key to analyzing regional climates.

  • Bars = Rainfall

  • Line graph = Temperature

  • Gray line = Relative Humidity

🔍 Quiz Insights:

  • Highest precipitation = September

  • Highest temperature = May

  • Lowest humidity = April

🌊 8. El Niño, La Niña, and ENSO

ENSO = El Niño-Southern Oscillation
Cycles of ocean surface temperature changes in the Pacific.

Phase

Eastern Pacific

Western Pacific

Philippine Effect

El Niño

Warmer

Drier

Drought, weak monsoons

La Niña

Cooler

Wetter

Flooding, strong monsoons

🔍 Quiz: El Niño brings dry weather to the Philippines, not rain.

🌱 9. Human Impact on Climate

  • Greenhouse gases trap heat → enhanced greenhouse effect → global warming

  • Main gases: CO₂, CH₄, N₂O, H₂O vapor

  • Methane (CH₄) is less common but more potent than CO₂

🔍 Quiz: True – Methane causes warming despite being less abundant.

🛡 10. Climate Change in the Philippines

  • More intense typhoons

  • Urban heat islands

  • Rising sea levels

  • More frequent flooding and droughts

🧰 11. Adaptation and Mitigation Strategies

Problem

Solution

Urban flooding

Green infrastructure, permeable pavements

Sea-level rise

Sea walls, coastal buffer zones

Farming under drought

Climate-resilient crops, rainwater storage

Extreme heat

Tree planting, green spaces

🔍 Quiz: Best strategy = early warning systems + disaster planning
