16. What is WEATHER?  Weather tells what is going on in the atmosphere at a particular place and time.  Weather refers to the condition of the atmosphere at a particular place and a short period of time.  Weather varies or changes all the time.  Meteorology is the study of weather.

18. What’s the difference between WEATHER and CLIMATE?  Climate, on the other hand, tells about the weather in a particular place over a LONG period of time.  Climate refers to the average weather condition in a particular wide area or place in a long period of time.  PAGASA stands for – Philippine Atmospheric Geophysical Astronomical Services Administration.

20. SEASON  A season is a subdivision of the year, marked by changes in weather, ecology, and hours of daylight. Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution.  The Four major Seasons are Winter, Spring, Summer and Fall.  Tropical Seasons: Dry and Wet seasons

23. Factors affecting WEATHER  Factors affecting weather are things, conditions or phenomena’s in which influence the atmospheric condition of a certain place in a particular time.  Such factors are as follows:  Air Temperature  Air Pressure  Air Movement/Wind  Humidity  Air Masses and Fronts  Precipitation  Cloud Formation.

24. Air Temperature  Air temperature greatly affects weather. The amount of heat absorbed by the air causes it to move.  Temperature is the amount of heat energy present in an object.  The part of the atmosphere nearest to the earth picks up great heat from earth which absorbs some of the heat given off by the sun. As air close to the earth is heated, warm air goes up because it is lighter then the heavier, cooler air moves down.  Thermometer is a device which we use in measuring Temperature.

25. Air Pressure  Air also exerts pressure.  Pressure is the force applied over a given area.  Because air has weight, it presses on all objects it touches. Air pressure is controlled by air temperature, the amount of water vapor(Humidity) and the altitude (the height of the place)  Warm air is lighter than cold air and therefore has less pressure than cold air. An increase in pressure can b caused by a decrease in temperature.  Air pressure can be measured by a device called a Barometer. The unit for pressure is called as atmosphere or atm.

26. Barometer the very first barometer was invented by an Italian scientist named Evangelista Torricelli in 1644

27. OOOOOOOOOPS!

28. A duck or a rabbit? Hmmm?

29. Air Movement  Wind is known as moving air.  When the air moves vertically either updraft of downdrafts, they are called as convection currents. Thus air rises in circular patterns.  The sun’s energy rays hit different parts of the earth at different angles. Because of this, all parts of the earth is heated unequally or not equal.  The difference between the temperatures of certain places allows air to move creating what we call as wind.  Air moves from a hot place going to a cold place. Best examples are what we call as sea breeze and land breeze.

30.  An anemometer is a device use in measuring wind speed.  A wind vane is a device use in telling the direction of wind.

31. Humidity  Humidity refers to the amount of water vapor present in air.  More water vapor in air means there is a high humidity. The air is said to be saturated.  Humidity is greatly affected by temperature. The higher the temperature more water will evaporate and turn into water vapor thus saturating air.  Dew point is the temperature at which water vapor condenses forming dews or clouds.  Hygrometer is a device used in measuring the humidity of air.

32. Hygrometer and Psychrometer

33. Air masses and fronts  An air mass is very large amount of air that has the same temperature and humidity. It can cover thousand of kilometers of the earth’s surface, and it can be many kilometers high. Once formed, the air mass begins to move through the atmosphere.  As air masses move, sometimes a cold air mass meets a warm air mass. The boundary or surface where the two air masses meet is called a front. If a cold air mass flows under the warm air mass a cold front is formed. A cold front brings heavy rains and thunderstorms.

34. Precipitation  Precipitation is the process by which condensed water vapor falls from the clouds to the ground.  A rain gauge is used to measure the amount of rainfall falling in a certain place.  Types of precipitation  Rain  Snow  Sleet  Hail

37. OOOOOOOOOPS!

38. How many black dots do you see?

39. Cloud Formation  Clouds are formed from the condensation of water vapor that went up into the upper troposphere. A temperature range from 0 to negative temperatures allows cloud formation.  Clouds are good determiners of weather  A clear sky without clouds means a sunny weather.  Presence of cirrus and stratus clouds also signify a good weather condition.  Cumulus clouds indicates that it would be a cloudy weather.  Nimbus clouds also known as Rain clouds. Usually dark in color because its filled with water vapor ready to precipitate down to the ground.
