Year 7 Knowledge Organiser: Weather & Climate Key words The Water Cycle Evaporation When the sun heats up water from the sea and it goes into the air Shows the circulation of the Condensation When water vapour cools and turns into clouds earth’s water Precipitation Rain, snow, sleet, or hail that falls to or condenses on the ground Surface run off When water runs off the surface of the ground Groundwater flow When water flows through the rocks and soil under the ground Transpiration When the sun heats up water from the leaves of the trees Weather Symbols Weather Weather is what it is like at a particular place at a particular time. You often look at the weather on a daily basis (short time period) Weather Symbols Weather symbols are used on weather maps as shorthand for the conditions in the atmosphere Weather Forecast Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time Climate Climate is what the weather is like over a long time period. For example over 30 years. It uses records of the weather to say what the climate is like. Measuring the Temperature Temperature is a degree of hotness or coldness the What do we measure? weather can be measured using a thermometer Temperature Wind Direction & Wind direction is reported by the direction from Wind Speed which it originates. Wind speed is measured in Precipitation, e.g. rainfall km/h. Measured using an Anemometer Wind speed and direction Barometer An instrument measuring atmospheric pressure, used especially in forecasting the weather cover and visibility Rain Gauge A device for collecting and measuring the amount of rain which falls Air pressure Thermometer An instrument for measuring and indicating Humidity (amount of water vapour in the air) temperature measured in degrees Celsius Oktas Scale An okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station. Sky conditions are estimated in terms of how many eighths of the sky
