Weather observers record weather conditions every day at scheduled times, compile the information into meteorological messages according to international codes and transmit it to different centres.
They measure temperature changes, humidity, atmospheric pressure, wind speed and wind direction twice a day. Precision instruments are used to make the observations and the weather observers must keep these instruments in excellent working condition.
The nature of the services rendered by the Weather Bureau makes it necessary to conduct observations 24 hours a day. Weather observers, therefore, have to work shifts.
