Answers
Answer:
Step-by-step explanation:
Weather can be described using terms such as wet or fine, warm or cold, windy or calm, so why is there a need to measure the weather? For most people, a description of the weather is adequate but for many businesses more detailed and accurate measurements are required. The science of studying weather is called meteorology. Weather scientists or meteorologists measure temperature, rainfall, pressure, humidity, sunshine and cloudiness and they make predictions and forecasts about what the weather will do in the future. This is important for giving people advance notice of severe weather such as floods and hurricanes.
Temperature, or the hotness or coldness of a substance, is measured with a thermometer. A thermometer is usually made from a tube of hollow glass with a bulb shaped base. The bulb is filled with a liquid, usually mercury which expands as temperatures rise and falls as temperatures drop. A scale on the thermometer can be read to find out what the temperature is. Celsius (°C) is the most common scale for thermometers.
To make sure that the thermometer is measuring the temperature of the surrounding air, it must be shaded from direct sunlight and should have sufficient air circulating around it. The Stevenson Screen was designed by Thomas Stevenson (father of Robert Louis Stevenson) to create an enclosure with as near as possible temperature as the air outside.
The Stevenson Screen is a wooden box with slatted sides, a sloping roof and legs to keep the screen off the ground. It is painted white to reflect the sun and it has opening doors which can be locked for security.
Figure 2.1 shows a maximum-minimum thermometer. This type of thermometer measures both the highest (maximum) and lowest (minimum) temperature over a period of time, usually one day (24 hours).
