- 2. CHAPTER 2 VARIABLE WEATHER AND CHANGING CLIMATE A Continuing Challenge? In this Chapter you will explore three key questions: 1.Why do different places experience different weather and climate? 2.What is happening to the earth’s climate? 3.Is the weather becoming more extreme? 2
- 3. Gateway 1: Why do different places experience different weather and climate? a. What is the difference between weather and climate? b. What are the elements of weather? -Temperature, relative humidity, clouds, rainfall, air pressure and wind. c. What are the climatic types and where are they experienced?

- 6. Comparison chart Climate Weather Definition: Describes the average conditions expected at a specific place at a given time.A region's climate is generated by the climate system, which has five components: atmosphere, hydrosphere, cryosphere, land surface, and biosphere.[1] Describes the atmospheric conditions at a specific place at a specific point in time. Weather generally refers to day-to-day temperature and precipitation activity Components: Climate may include precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, frost, and hail storms over a long period of time. Weather includes sunshine, rain, cloud cover, winds, hail, snow, sleet, freezing rain, flooding, blizzards, ice storms, thunderstorms, steady rains from a cold front or warm front, excessive heat, heat waves and more Forecast: By aggregates of weather statistics over periods of 30 years By collecting meteorological data, like air temperature, pressure, humidity, solar radiation, wind speeds and direction etc. Determined by: Aggregating weather statistics over periods of 30 years ("climate normals"). Real-time measurements of atmospheric pressure, temperature, wind speed and direction, humidity, precipitation, cloud cover, and other variables About: Climate is defined as statistical weather information that describes the variation of weather at a given place for a specified interval. Weather is the day-to-day state of the atmosphere, and its short-term (minutes to weeks) variation Time frame: Measured over a long period Measured for short term Study: Climatology Meteorology 6

- Photographs showing Central Park, Manhattan, United States of AmericaSuggested activity:Ask students to identify which season each photo depicts. From top left in a clockwise direction- Winter, spring, autumn, summer.Ask students which season Singapore is most likely to experience. SummerAsk them why Singapore does not experience the other three seasons. Location: Singapore is located in the Tropics, where temperatures are consistently high throughout the year; students will learn more under ‘Latitude’ in this GatewayFor NA students:Help them identify the seasons by observing the vegetation cover. In winter, there will be no vegetation cover, in autumn, it will be red; the vegetation cover is green in spring and summer, with more vegetation cover present in summer.For question on why Singapore does not experience other three seasons: you can use the world map to locate USA and Singapore to help the studentsImages: © Songquan Deng/Dreamstime.com and © Guter/Dreamstime.com
- For studentsAsk them what are the kind of weather they have experienced in Singapore for the past year. (Rainy, sunny)Question them why they did not experience the 4 seasons. (Different locations)Teacher to prompt them for examples and thereafter use map to show them it is generally based on latitudes.
