On page 387, it tells about how weather balloons work. Weather balloons provide data used to make the country's weather forecasts. It first talks about the system. The balloons are released at the same time in all countries-at 6:00 and 18:00 hours (GMT). After they get the data from all over the world it goes to a central computer in Maryland.

Weather balloons are very complex.
