What is the elements of weather?Show answer
Weather is the day-to-day state of the atmosphere. Its main elements are:
What is measuring temperature?Show answer
Temperature is measured with a thermometer, in degrees Celsius. To get a true reading of the air temperature, the thermometer is kept in a Stevenson screen: a white, louvred box that gives shade from direct sun, reflects heat with its white colour, lets air flow through its slats, and is raised off the ground. A maximum-minimum thermometer records the highest and lowest temperatures of the day.
What is measuring rainfall?Show answer
Rainfall is measured with a rain gauge, in millimetres. A funnel collects rain into a measuring cylinder. The gauge is placed in the open, away from buildings and trees, with the funnel a set height above the ground to avoid splash. It is read at the same time each day and then emptied.
What is measuring humidity?Show answer
Humidity is measured with a hygrometer (often a wet-and-dry-bulb thermometer). The difference between the two thermometer readings is used to work out the relative humidity, given as a percentage. High humidity means the air holds a lot of water vapour, which is typical of tropical climates.
What is q1?Show answer
Name the instrument used to measure wind speed and the instrument used to measure wind direction. [2 marks]
What is q2?Show answer
State the unit used to record rainfall and the unit used to record air pressure. [2 marks]
What is q3?Show answer
Explain one feature of a Stevenson screen and how it helps give an accurate temperature. [2 marks]
