Science 6: Weather Conditions and Factors

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

• 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

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

Precipitation

• 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.
