Question

how are computers used in producing weather forecasts?
they compile data from multiple instruments.
they collect air temperature and air pressure data.
they eliminate the need for human meteorologists.
they transmit data on developing weather systems from space.

Explanation:

Computers play a crucial role in weather forecasting. They can compile data from multiple instruments (such as weather stations, satellites, radars etc.). Collecting air - temperature and air - pressure data is usually done by specific instruments (like thermometers and barometers), not just computers. Computers cannot eliminate the need for human meteorologists as human interpretation and expertise are still required. Transmitting data from space is mainly the function of satellites, not the general role of computers in the broader sense of data compilation for forecasts.

Answer:

They compile data from multiple instruments.
