49. ______ 3. When air becomes colder clouds form. ______ 4. Rain that falls to the ground may sink into the ground or flow on the surface as runoff .

50. Establishing a purpose for the lesson Let pupils read this: “ Whether the weather be fine, Whether the weather be not, Whether the weather be cold, Whether the weather be hot, We will weather the weather Whether we like it or not.” What does the rhyme imply? What is the weather today? How about the climate in your place? Are they different? Let’s find out.

51. Developing mastery Tell whether the statement describes the weather or climate . ____1 . It is the temporary condition of the atmosphere in a given place at a particular time.

52. ___2 . It is what the forecaster on the TV news predict each day. ___3 . Is the combination of temperature, moisture, wind and sunshine at a place over a period of years. ___4 . It is how the atmosphere “behaves” over a period of time. ___5 . It varies from day to day

53. Finding practical applications of concepts and skills in daily living Why do we have to know the weather for the day? Life is like weather. Sometimes it is bright and shiny, and sometimes it is dark and gloomy. There are always storms and misunderstandings from time to time. To weather the storms mean overcome some difficulties or problems in our lives.

54. Making generalizations and abstractions about the lesson What are the differences between weather and climate? Weather > the day to day or time to time condition of the atmosphere in certain area. > It affects our daily activities . > The weather is fine when the sky is bright, sunny, with few clouds, and no rain; it is fair when there are clouds and rain may occur in isolated patches,

55. > Through the use of modern weather equipments , meteorologists are able to predict weather conditions at any given time. Knowing weather changes help us plan worthwhile activities. We can also prepare better during harsh weather conditions. In this way we can save lives and prevent damage to properties.

56. > Climate is the total weather conditions in a region over a longer period of time. The weather at a certain place such a Manila may be cold and have a warm, dry, sunny climate. Climate is the combination of temperature, moisture, wind and sunshine at place over a period of years. The study of climate is called climatology and scientist is known as a climatologist.

57. Evaluating learning Write W if the statement describes the weather and C if it describes the climate. ___1 . It happens at a very short period of time-even only for a day. ___2 . It occurs for a long period of time. ___3 . It is the average weather in a place over many years .

58. ___4 . It varies from day to day and from one place to another. ___5 . Is the combination of temperature, moisture, wind and sunshine at a place over a period of years.

59. Week 3 Day 5 Describing the Different Weather Disturbances

60. Review Can you differentiate weather from climate ?

61. Establishing a purpose for the lesson Recall what happened when you saw a flash of lightning from a distance . You heard thunder, wind blew , and it rained hard. That was an experienced of just one weather disturbance. What do you call it?

62. Presenting examples/ instances of the lesson Group Activity: “Types of Weather Disturbance” Approach: Collaborative Strategy: Peer Teaching Activity: AFA (The teacher pre- assigned the group and the topic to be discussed by each group. Teacher should check first the output of the group) I . Problem: What are the types of weather disturbances? II. Materials: chart or Powerpoint presentation or video presentation can be used by the reporter of each group III Procedure: a. Listen to each group report. b. Understand and jot down important facts about the different weather disturbances. Group I- Storm Group II- Thunderstorms Group III- Hurricane and Tornadoes Group IV- Tropical Cyclone

63. TYPES OF WEATHER DISTURBANCES

64. A storm is any disturbed state of an environment or astronomical body's atmosphere especially affecting its surface, and strongly implying severe weather. It may be marked by significant disruptions to normal conditions such as strong wind, tornados, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc . The English word comes from Proto-Germanic * sturmaz meaning "noise, tumult".[2]

65. Thunderstorms are small, intense weather systems that make strong winds, heavy rain, lightning, and thunder. Thunderstorms can happen anywhere with two conditions: the air near the Earth's surface must be warm and moist (with lots of liquid), and the atmosphere must be unstable.[1] 100 lightning bolts hit the earth every second, and at any one moment, about 1,800 thunderstorms happen around the earth.[2 ] Thunderstorms are rare in cold weather. When they happen, it is called thundersnow .

66. A tropical cyclone is a circular air movement over the warm ocean waters in the warm part of Earth near the equator. Most tropical cyclones create strong winds and heavy rains. While some tropical cyclones stay out in the sea, others pass over land. They can be dangerous because of flooding and because the winds pick up objects, including things as big as small boats. They can throw these things at high speeds . Tropical cyclones, hurricanes or typhoons form when convection causes warm, moist ocean air to rise. They begin as a group of storm winds when the water gets as hot as 80 °F (27 °C) or hotter. The Coriolis effect made by the Earth's rotation causes the winds to rotate. Warm air rises quickly and then it gets pushed aside as it cools. These storms usually move westward in the tropics, and later move north or south into the temperate zone. The "eye of the storm" is the center. It has little rain or wind. The eye wall has much rain and the strongest winds. It is surrounded by rain bands and an area of strong winds.

67. A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters, whirlwinds or cyclones,[1] although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern.[2] Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than 110 miles per hour (180 km/h), are about 250 feet (80 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (480 km/h), are more than two miles (3 km) in diameter, and stay on the ground for dozens of miles (more than 100 km).

68. Storm - is a violent disturbance in atmosphere marked by sudden changes in air pressure and rapid air movements.

69. Thunderstorm – is a localized storm cloud that produces thunder and lightning . It is one of the most common types of weather disturbances that is experienced in the country.

70. Hurricane - is a tropical storm with sustained winds of at least 120km/hr . > considered the most violent storms on Earth, have several names depending on the location where they are formed . 1. When winds in a tropical cyclone occurs in the Atlantic or central Pacific Ocean, it is called a hurricane .

71. 2. In western Pacific Ocean in some parts of asia like Phillipines , weather disturbances that occur are referred to as typhoons . 3. In the Indian Ocean, they are called cyclones . Hurricanes rotate in a counterclockwise direction around an “eye.” The center of the storm or “eye” is the calmest part . It has only light winds and fair weather .

72. Tropical cyclones are areas of low pressure that contains rising warm air. Classification of tropical cyclone according to maximum speed: 1. Tropical depression- has maximum sustained wind speed of less than 63 kph . When it gains speed, it becomes a storm and eventually a typhoon.

73. 2. Tropical storm- has maximum sustained wind speed which ranges from 63 to 118 kph . 3. Typhoon- has a wind speed greater than 118 kph

74. Evaluating Learning Identify the type of weather disturbance being described below: Choose your answer from the word inside the box. Tornado tropical cyclone storm hurricane thunderstorm ____1 . It rotates in a counterclockwise direction around an” eye “.

75. Tornado tropical cyclone storm hurricane thunderstorm ___2 . It is localized storm cloud that produces thunder and lightning. ___3 . A violent disturbance in atmosphere marked by sudden changes in air pressure and rapid air movements.

76. Tornado tropical cyclone storm hurricane thunderstorm ___4 . These are classified into three according to the maximum speed of the wind near the center.. ___5 . A whirling, funnel-shaped windstorm, which often develops from a thunderstorm.
