Study Notes

Air Pressure

  • Air pressure is the force of the air on a given surface divided by the area of that surface.
  • High-pressure areas are regions with higher pressure than the surroundings.
  • Low-pressure areas are regions with lower pressure than the surroundings.
  • Most storms occur in low-pressure areas, like in the ocean during summer.
  • Barometer is used to measure air pressure.


  • Wind is the horizontal movement of air.
  • Wind speed has an average range from 8 to 24 km/h near Earth’s surface and can be higher during intense storms.
  • Anemometer is used to measure wind velocity and a wind vane is used to determine the direction of the wind.


  • Clouds are tiny droplets of water suspended in the air.
  • Clouds are formed as warm air rises and cools.


  • Precipitation is water that falls to the earth in solid or liquid form, like rain, snow, sleet, or hail.
  • Rain gauge is an instrument used to measure the amount of liquid precipitation over an area in a predefined area, over a period of time.

Seasons and Weather Patterns in the Philippines

  • The Philippines has a warm and humid climate all year round.
  • The Philippines has two pronounced seasons: wet and dry.
  • Wet season is characterized by the rainy season with thunderstorms, starting in June and peaking in July and September.
  • Dry season is characterized by hot and cloudless days, between January and May, with occasional rain showers.

Factors Affecting the Seasons of the Philippines

  • Location of the Philippines near the equator affects the seasons.
  • Prevailing winds, such as the Southwest Monsoon (Habagat) and Northeast Monsoon (Amihan), affect the seasons.
  • Air masses that pass over the Philippines, such as warm air masses from the Equatorial Oceans, affect the weather.

Unusual Weather Patterns

  • El Niño occurs when the weather pattern makes the weather warmer than normal.
  • La Niña occurs when the weather pattern makes the weather colder than normal.

Weather Forecast

  • Weather forecast is a statement of expected weather conditions in a given region over a period of one hour to a few days in advance.
  • Meteorologists use weather instruments to analyze weather elements and make forecasts.

Weather Elements and Instruments

  • Temperature is the measure of the degree of hotness or coldness of the air.
  • Humidity is a measure of moisture present in the air.
  • Hygrometer is used to measure relative humidity.

Learn about weather conditions, factors affecting weather, and the dangers of severe weather in this quiz. Prepare yourself for traveling to the Philippines by understanding how weather changes and its impact on day-to-day activities.
