Ppt elements that affect weather

  1. 1. Elements that affect weather - cloudiness - precipitation -Recording weather condition Prepared by: Ms. Shirley Puaso-Valera Grade 3 St. Fancis/St.Augustine/St.Maria Goretti SY 2013-2014
  2. 2. Key Questions A. How do factors affect the weather? B. Why do we need to know the weather for the day?
  3. 3. Objectives A. Infer that weather changes from day to day. B. Identify the elements that affect the weather. C. Record in a chart the weather for the day/ week using symbols. D. Analyze how the different elements can affect the weather condition.
  4. 4. Look outside. Describe the weather for the day through the movements of the clouds.
  5. 5. Clouds -Is a collection of droplets of water floating in the air. -Found in the lower part of the atmosphere, troposphere
  6. 6. Clouds -Some clouds are formed in the stratosphere ,too -The shape and the position of the clouds tell the direction and speed of the wind in the sea.
  7. 7. Clouds - Tells the air how much water vapor is in
  8. 8. What are the kinds of clouds? How clouds help in telling the weather for the day?
  9. 9. Kinds of Clouds • Stratus clouds - the indicate light rainy weather - can be seen early in the morning or late in afternoon
  10. 10. Kinds of Clouds • Cirrus clouds - are thin , curly , and feathery - they are formed high up in the sky where air is thin and wind does not blow too much
  11. 11. Kinds of Clouds • Cirrus clouds - the water vapor rises straight up high into the sky to form small lumps of clouds that look like feathers - they are formed when there is not much moisture in air
  12. 12. Kinds of Clouds • Cumulus clouds - are heaped and fluffy like cotton - they are formed when the wind moves straight up in the sky
  13. 13. Kinds of Clouds • Cumulus clouds - generally indicate fair weather but when they become too big and grayish, they may bring bad weather characterized by lightning , thunder, and strong rain.
  14. 14. Kinds of Clouds • Stratus clouds - are spread out in the sky - they are formed when the wind moves horizontally, usually cover a large area,
  15. 15. Kinds of Clouds • Stratus clouds - the indicate light rainy weather - can be seen early in the morning or late in afternoon
  16. 16. Kinds of Clouds • Stratus clouds - it indicate light rainy weather - can be seen early in the morning or late in afternoon
  17. 17. Kinds of Clouds • Nimbus clouds(Cumulonimbus) - are rain clouds - appears grayish , bluish, or blackish
  18. 18. Kinds of Clouds • Nimbus clouds(Cumulonimbus) - composed of bigger droplets ready to fall as rain - seen during heavy rain or thunderstorm
  19. 19. Cloud in a jar activity: • Observe • Discussion on the result of the activity
  20. 20. Video clip viewing
  21. 21. Water Cycle
  22. 22. The water cycle affects both climate and weather
  23. 23. • When clouds cover the entire sky , the temperature directly below the clouds is lower. It is cooler because clouds reflect the heat of the sun in outer space •Clouds protect us from sun’s radiation by covering the space above us.
  24. 24. Precipitation • Water that falls from the clouds • Air temperature determines the form of precipitation that falls • 4 main types of Precipitation: Rain, Sleet, Snow and Hail
  25. 25. Types of Precipitation Rain Sleet Snow Hail
  26. 26. Different kinds of precipitation • Snow , sleet and hail – – They are solid Droplets of water in the clouds become solid when the temperature of the air is very low and water becomes frozen
  27. 27. Different kinds of precipitation • Drizzle or shower
  28. 28. Different kinds of precipitation • Thunderstorm – raindrops are big and they pour for about an hour - usually accompanied by lightning and thunder
  29. 29. Severe Weather Thunderstorms Lightning Tornadoes
  30. 30. More Severe Weather Hurricanes Blizzards
  31. 31. • When rain fall heavily, the weather is described as rainy. In the Philippines, rainy weather is accompanied by thunder and lightning. •In Metro manila and other areas , heavy rains are usually followed by floods.
  32. 32. Instruments used to measure weather condition • Rain gauge - a collection of pail with a ruler to measure the depth of rain water.
  33. 33. Instruments used to measure weather condition
  34. 34. • A psychrometer is used to measure humidity. It has two bulbs in order to function properly. The two bulbs are wet and dry. The temperature difference between the two is noted.
  35. 35. • An Anemometer is an instrument which is used to measure the speed or force of wind and is mostly found in weather stations. This term was derived from a Greek word known as 'enomos' which means 'wind'.
  36. 36. • Years ago farmers would use the wind vane to keep an eye on the winds direction. If the wind was blowing strong from a certain direction it would mean rain was on it's way.  At small public airports they have a wind sock flying so a pilot can tell how the wind is blowing to prepare for a landing/takeoff.
  37. 37. PAGASA • (Philippine Atmospheric , Geophysical, and Astronomical Service Administration • observes weather conditions, issued warning signals and storms
  38. 38. PAGASA • Philippines is always visited by tropical cyclones because it is in the typhoon belt. • Tropical cyclones are weather disturbances when it grows, it develops into a typhoon or bagyo.
  39. 39. Weather forecast
  40. 40. Weather Forecast
  41. 41. Weather Forecast
  42. 42. Generalization • Different factors affect and determine weather conditions. • Weather condition changes from time to time , thus everybody should always be ready.
  43. 43. Valuing • Always be ready to protect ourselves from the different weather conditions.
  44. 44. Evaluation Answer page 325 A.Fill in the blanks with the correct words to complete the sentences. B.Match the weather instruments to its use.
  45. 45. Can you identify these clouds?
  46. 46. Other Cloud Types Cirrocumulus Stratocumulus Cirrostratus Cumulonimbus
  47. 47. More Cloud Types Altostratus Altocumulus Nimbostratus
  48. 48. • Earth’s tilt at an angle of 23.5 degrees to the plane of its orbit around the Sun. • Major components of Earth that influence weather are: atmosphere, land forms, and water. About 70% of Earth’s surface is • covered by oceans.
  49. 49. THANK YOU FOR LISTENING
