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.

The compile data from multiple instruments

Explanation:

NWS super computers hold numerical modeling data for weather forecasting models. These computers make use of virtually all observational data that the NWS collects. This data comes from satellites, weather balloons, buoys, radar, and more.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
