4 Slide 4 / 103 Intro to Weather & Climate Return to Table of Contents

5 Slide 5 / 103 Activity: Collecting Weather Data Use your observation skills to observe the weather in your area.

6 Slide 6 / 103 Weather & Climate Can you describe the weather in your area today? Can you describe the climate of your area?

7 Slide 7 / 103 Weather & Climate The terms weather and climate refer to two different things. Weather is a description of the current conditions of the atmosphere in a particular place. Climate is a description of the average weather of a particular place.

8 Slide 8 / 103 Weather & Climate In the boxes below, decide if each description is an example of weather or climate. Click on the box to check your answers. There will probably be a thunderstorm weather this afternoon. The average yearly climate rainfall is 100 cm. It is currently sunny with a weather temperature of 80. Summers are warm with daily climate afternoon thunderstorms.

9 Slide 9 / 103 Weather Think about your weather today. What adjectives can you use to describe it?

10 Slide 10 / 103 Weather Look back at your adjectives. How many different categories of weather descriptions can you think of? (For example, if you wrote "hot" or "cold", this category would be temperature.)

11 Slide 11 / 103 Weather Weather is usually described by the following categories: temperature humidity precipitation visibility (cloudiness) sunshine wind In this unit, we are going to focus on temperature, precipitation and wind. How many of these categories can you describe by looking at the pictures below?

12 Slide 12 / Weather and climate are two different terms that describe the same thing. True False

13 Slide 12 (Answer) / Weather and climate are two different terms that describe the same thing. True False Answer False [This object is a pull tab]

14 Slide 13 / 103 Temperature Return to Table of Contents

15 Slide 14 / 103 Temperature What is temperature? Click in the box to see a definition. Temperatureis a measure of heat in a material. When we talk about weather, temperature is the amount of heat absorbed by Earth.

16 Slide 15 / 103 Sunlight Earth's temperature is a result of the sun's heat energy. Think back to what you learned in earlier grades. Do all areas of the Earth receive equal amounts of sunlight? Write your thoughts below and then move to the next slide to see the answer.

17 Slide 16 / 103 Sunlight Earth is tilted on its axis. This means that some areas of Earth receive direct sunlight while other areas receive indirect sunlight.

18 Slide 17 / 103 Sunlight Suppose that you are very cold and are trying to warm yourself by the fireplace. Where should you stand to feel the warmest: right in front of the fireplace or off to the side?

19 Slide 18 / 103 Sunlight This same idea applies to temperature on Earth. The equator receives direct sunlight and therefore has the highest temperatures. Other regions of Earth receive varying amounts of indirect sunlight and have lower temperatures than the equator.

20 Slide 19 / Earth receives heat energy from the sun. True False

21 Slide 19 (Answer) / Earth receives heat energy from the sun. True False Answer True [This object is a pull tab]

22 Slide 20 / Earth is heated unevenly due to. A the sun's tilt on its axis B the Earth's tilt on its axis C the speed of Earth's rotation D the speed of Earth's revolution

23 Slide 20 (Answer) / Earth is heated unevenly due to. A the sun's tilt on its axis B the Earth's tilt on its axis Answer C the speed of Earth's rotation D the speed of Earth's revolution B [This object is a pull tab]

26 Slide 22 / 103 Activity: Thermometer Temperature is measured by a thermometer. By building your own thermometer, examine how a thermometer works.

27 Slide 23 / 103 Activity: Thermometer Can you summarize how a thermometer works? Click below to see an explanation. As the liquid absorbs heat, its volume increases and it rises higher in the thermometer. A higher level of liquid indicates a higher temperature.

28 Slide 24 / 103 Precipitation Return to Table of Contents

29 Slide 25 / 103 Demo: Water Cycle in a Jar Precipitation is fueled by the water cycle. Watch the steps of the water cycle during this activity.

30 Slide 26 / 103 Water Cycle Review Let's review the water cycle. Put the star on precipitation. Put the triangle on evaporation. Put the circle on condensation. Put the square on the energy source.

31 Slide 26 (Answer) / 103 Water Cycle Review Let's review the water cycle. Put the star on precipitation. Put the triangle on evaporation. Put the circle on condensation. Put the square on the energy source. Answer The star goes on the "rain and snow.". The triangle goes on the the up arrow. The circle goes on the white cloud. The square goes on the sun. [This object is a pull tab]

32 Slide 27 / 103 Water Cycle Review

33 Slide 28 / 103 Precipitation So, how does the water cycle lead to precipitation? 1. Water evaporates into the air. 2. As water vapor cools, it condenses onto dust particles in the atmosphere. This creates clouds. 3. Water particles in clouds bump into each other, sometimes combining into larger water particles. 4. When the water particles become too heavy for the cloud, they fall to the ground as precipitation.

34 Slide 29 / 103 Precipitation How many different types of precipitation can you think of? Write them below: What important factor causes these different types of precipitation? Click in the box to find out. Temperature

35 Slide 30 / 103 Precipitation If the temperature outside is above 0 O C, precipitation will fall as rain. If the temperature outside is below 0 O C, precipitation will fall as snow. At exactly 0 O C, it will be a mix of rain and snow.

36 Slide 31 / 103 Case Study: Developing Storm This storm is beginning to develop over your neighborhood. Think about what you have learned about precipitation. What factor will determine how much precipitation falls in the storm? The amount of water particles in the cloud. What factor determines what kind of precipitation falls? Temperature

37 Slide 32 / 103 Rain Gauge Meteorologists use a rain gauge to measure precipitation. The precipitation falls into the rain gauge over time. By reading the side of the rain gauge in milliliters or liters, you can find the amount of precipitation that has fallen. This picture from NASA is a rain gauge set to record the precipitation of this storm.

38 Slide 33 / 103 Precipitation Flowchart Use the space below to draw a flowchart of how precipitation forms.

39 Slide 34 / Precipitation occurs when water falls from a cloud. It can be solid or liquid. True False

40 Slide 34 (Answer) / Precipitation occurs when water falls from a cloud. It can be solid or liquid. True False Answer True [This object is a pull tab]

41 Slide 35 / The temperature that rain turns to snow is O C. A 0 B 10 C 100 D It varies greatly.

42 Slide 35 (Answer) / The temperature that rain turns to snow is O C. A 0 B 10 C 100 D It varies greatly. Answer A [This object is a pull tab]

43 Slide 36 / 103 Clouds As you now know, cloud formation is an essential ingredient for precipitation. But...how do clouds form in the first place? Brainstorm some ideas below. (Hint: Three things are necessary for cloud formation.)

44 Slide 37 / 103 Demo: Cloud in a Jar Watch closely to see the ingredients necessary to make a cloud!

45 Slide 38 / 103 Cloud Formation Three things are necessary for cloud formation: 1. moist air (evaporation) 2. cooling 3. dust or other tiny particles in the air What are the sources of these three things in the activity and in nature? Cloud Activity Nature

46 Slide 38 (Answer) / 103 Cloud Formation Cloud Activity: Warm water led to evaporation. Three things Ice are cubes necessary created for cooling. cloud formation: Match created smoke particles. 1. moist air (evaporation) 2. Nature: cooling 3. The dust sun or causes other tiny evaporation. particles in the air The atmosphere provides a What are the cooling sources environment. of these three things in the activity and in nature? There are a variety of particles present in the atmosphere. [This object is a pull tab] Cloud Activity Nature Answer

47 Slide 39 / 103 Cloud Formation Remember back to last year's science class. Warm air expands and can hold more water. Cool air contracts and can hold less water. As air evaporates and rises, it expands and cools. Cool air cannot hold as much water as warm air, so some of the vapor condenses around tiny particles in the air. When several of these particles gather together, they form clouds.

48 Slide 40 / 103 Types of Clouds Meteorologists classify clouds based on their shape, how high in the sky the clouds are, and what the clouds are made of. Understanding cloud types helps meteorologists to predict the weather.

49 Slide 41 / 103 Stratus Clouds Stratus clouds are large clouds that cover the entire sky. They form low in the atmosphere and are often grey in color.

50 Slide 42 / 103 Cumulus Clouds Cumulus clouds are also found low in the atmosphere, but they are fluffy and white. Cumulus clouds form alone and there is usually blue sky in between them.

51 Slide 43 / 103 Cirrus Clouds Cirrus clouds form very high in the atmosphere where there is very little water vapor. They form as very thin sheets of ice crystals and can look like horse tails or feathers.

52 Slide 44 / 103 Types of Clouds Stratus, cumulus and cirrus are the three main types of clouds. However, some clouds form as different variations of the three. Cirrocumulus clouds form as small puffs very high in the atmosphere. Cumulonimbus clouds are cumulus clouds that grow very tall and develop into thunderstorms.

53 Slide 45 / What are the requirements for cloud formation? (Select all that apply.) A a spark of electricity B evaporation C cooling D particles in the atmosphere

59 Slide 48 / 103 Case Study: Climograph Climograph of Calcutta, India As you now know, temperature and precipitation data can be shown in graph form. Sometimes, scientists put both sets of information on the same graph. This gives a quick snapshot of the typical weather in an area. This type of graph is called a climograph.

60 Slide 49 / 103 Case Study: Climograph In a climograph, time is on the x-axis and there are two y-axes, one for precipitation and one for temperature. Look at the graph below and answer the questions. Climograph of Calcutta, India 1. During which month are temperatures the highest? The lowest? 2.

72 Slide 57 / 103 Teacher Demo: Convection Using your knowledge about hot and cold molecules, can you make a prediction for this demonstration? Prediction: Result:

73 Slide 58 / 103 Wind Formation Warm air spreads out while cool air contracts. This means that warm air weighs less (less dense) than cool air. Warm air will always rise above cool air because cold air is heavier. When air masses interact based on these principles, we feel it as wind. Suppose that there is a warm air mass and a cool air mass next to each other due to the uneven heating of the Earth by the sun. What do you suppose would happen? Warm air Cool air

74 Slide 59 / 103 Wind Formation First, the warm air expands and rises. Warm air Cool air

75 Slide 60 / 103 Wind Formation There is now an empty spot where the warm air used to be. Warm air Cool air

76 Slide 61 / 103 Wind Formation The cool air moves in to fill the empty space left by the warm air. Warm air Cool air As the cool air moves in, we feel this air movement as wind.

77 Slide 62 / 103 Case Study: Sea Breeze Along the coastline, there is a daily sea breeze. This means that a breeze comes from the ocean onto the land during the day. Can you explain why this happens? Use the diagram below to sketch your ideas. (Hint: Air over land heats up faster than air over water.) Ocean Land

78 Slide 63 / 103 Case Study: Sea Breeze Since air over the land heats up faster, this air will rise. The cooler air over the water will move to fill in this empty space. This movement of air is felt as a breeze. Cool air Warm air Ocean Land

85 Slide 67 / 103 Weather Prediction Return to Table of Contents

86 Slide 68 / 103 Weather Prediction Meteorologists are scientists who study weather and create weather predictions. Meteorologists use computer models, observations and knowledge about weather patterns to create predictions.

87 Slide 69 / 103 Air Masses The lower level of our atmosphere is filled with different air masses. Meteorologists categorize air masses as having either high or low pressure. Remember these boxes of warm and cold air? Warm air Cold air If you held each box separately on your palm, which box would exert the most pressure onto your palm? (Which would press down onto your hand the hardest?)

92 Slide 73 / 103 Warm Front A warm front occurs when a mass of warm air moves towards a mass of cold air. When the warm air meets the cold air, what do you think will happen? Discuss as a class and write your ideas below.

93 Slide 74 / 103 Warm Front When a warm front approaches a cold air mass: 1. The warm air rises above the cold air. 2. As the warm air gradually rises, it then cools. 3. As the air cools, it condenses into clouds. Because of the cloud formation, warm fronts often bring light precipitation with them. After a warm front passes, the weather is usually warmer and more humid/wet than before.

94 Slide 75 / 103 Cold Front A cold front occurs when a mass of cold air moves towards a mass of warm air. During a cold front: 1. Cold air moves quickly. 2. Warm air is pushed upwards. 3. Clouds form when warm air condenses. 4. If warm air is pushed up very quickly and there is a big temperature change, thunderstorms may occur.

95 Slide 76 / 103 Cold Front As a cold front passes, there can be a short but intense storm system. After the cold front passes, the weather is usually cooler and drier than before.

125 Slide 94 / 103 Climate There are 5 climate zones on Earth: Tropical Dry Moderate Continental Polar These penguins live in Antarctica, a polar climate.

126 Slide 95 / 103 Climates Each zone can be divided into smaller categories. In what climate zone do you live?

127 Slide 96 / 103 Local Geography Climates are based on average temperatures, precipitation and wind. Local geography (mountains, waterways etc) is also important as this impacts weather conditions. The blue country is Gabon while the red country is Kenya. Both countries lie on the equator and receive the same amount of direct sunlight. However, Gabon has a tropical, wet climate while parts of Kenya have a very dry climate due to large mountains that remove moisture from the atmosphere.

128 Slide 97 / 103 Wind and Water Currents Global wind and water currents carry heat and moisture around the Earth. This affects the climate of different areas. Alaska and Iceland are located around the same latitude on Earth, which means they receive the same amount of sunlight. Iceland's average temperature is higher than Alaska's average temperature because warm water from the Caribbean flows past Iceland, warming the atmosphere. Only cold water currents flow past Alaska.

129 Slide 98 / 103 Climate By understanding climate, meteorologists can better predict weather for a particular area. Also, climate patterns help scientists develop solutions for areas subject to severe weather. Tornado Alley is an area of the country that experiences large collisions in warm and cold fronts that lead to tornados. Knowing this helps meteorologists study and predict tornados.

130 Slide 99 / 103 Climate Change Keeping records of how climates are changing over time can help scientists to better protect ecosystems. Global temperatures are increasing. How do you think this affects local plants and animals that live in your climate zone? Click here to watch a video describing world climates.
