Weather instruments

The weather instruments are :

  • Rain gauge

  • Wind vane

  • Windsock

  • Liquid thermometer

  • Air thermometer

A rain gauge measures the amount of rainfall.

Rainfall is measured in millimetres (mm).

A rain gauge is made up of a funnel and a collecting container. 

The funnel is normally wide enough.


Once rain is collected it is transferred to a measuring cylinder where the readings are taken and recorded.

The rain gauge should be placed on a flat ground in an  open field.

There should be no trees or  buildings next to the rain gauge
