Study Notes

Weather and Climate

Weather describes the short-term conditions of the atmosphere.
It includes temperature, precipitation, wind, and cloud cover.
Weather changes daily.
Climate describes the long-term average weather patterns in a particular area.
Usually, climate is measured over at least 30 years.
Climate considers elements like temperature, precipitation, and wind.

Objectives

Explain weather, weather patterns, and climate concepts.
Describe basic meteorological tools and their uses.
Explain how understanding weather patterns affects daily life.

Meteorology

Meteorologists are scientists who study weather and make predictions.
They use tools and instruments to collect data on temperature, humidity, wind speed, and other weather elements.
The collected information is used to understand and forecast weather patterns.

Weather Tools

Thermometers measure temperature.
Barometers measure air pressure.
Anemometers measure wind speed.
Weather satellites capture images to gather data on atmospheric conditions.

Weather Prediction

Meteorologists combine past information, current observations, and computer models to predict future weather conditions.
They evaluate patterns and trends in atmospheric conditions.
These predictions impact decisions about activities and safety.

Factors Determining Weather

Air Temperature: Higher temperatures lead to faster-moving air molecules and faster evaporation.
Air Pressure: Determined by the weight of air molecules and density.
Precipitation: Condensation of water vapor into larger droplets. Types include rain, snow, hail, and sleet.
Wind: Air moving from high to low pressure. In the Philippines, winds typically come from the East-Northeast. Categorized as cool/moist, blowing over water bodies, vs. warm/dry, blowing over landmasses.
Clouds: Indicate changes in weather.
- High Clouds: Cirrus clouds-thin, wispy clouds made of ice crystals, often indicate good weather.
- Mid-Level Clouds: Often white or gray clouds, indicating potential for rain.
- Low Clouds: Indicate fair weather.
- Cumulus clouds: Puffy, often white clouds, often associated with good weather.
- Stratus clouds: Large, flat, and featureless clouds, often indicate rain or snow.
- Nimbus clouds: Dark, heavy clouds that often signal thunderstorms and rain or snow.

Special Clouds

Special clouds indicate severe weather conditions.

Climate Zones

Tropical Climate: Warm temperatures, high humidity, and rainfall, often featuring rainforests.
Temperate Climate: Distinct seasons (warm summers, cool winters), moderate rainfall.
Polar Climate: Very cold temperatures, long harsh winters, little daylight, low precipitation, covered in ice and snow.
Dry/Desert Climate: Hot and dry, very little rainfall, extreme temperature fluctuations.

Four Seasons

Spring, Summer, Autumn, and Winter.

Importance of Weather and Climate Knowledge

Understanding weather helps us make decisions about daily activities (clothing, outdoor activities).
Preparedness reduces risks associated with extreme weather conditions.
Knowledge of weather and climate fosters responsible stewardship of the environment.
It assists in agriculture (planting, irrigating, and harvesting).
Important for understanding, preparing for, and protecting ourselves from weather events.

PAGASA

PAGASA is the Philippines' weather and climate authority.
