  • Satellites to see the situattion from the Sapce;
  • Radar to see where it's  raining;
  • Monitoring networks to receive information about atmospheric pressure or humidity.

The most important GM are:
  • GFS (American)
  • ECMWF (English)
There are lots of GM because every country has different physical conditions.
In a GM white lines rappresent the pressure variation at ground; the colours rappresents the pressure variation in height.
This is not the real forecast, it's only an hypothesys.

  • Trust automatic weather forecast;
  • Trust weather forecast for days too far.

For ages the humanity tried to make a prevision on the weather and today weather forecasting is an essential part of our life.
Nowadays we have new technologies and forecasting is more accurate.
