All other values are derived from these parameters. The atmospheric parameters described here are defined in <tt>[[$FG_ROOT]]/Environment/environment.xml</tt>, but they can be changed in-sim by selecting ''Environment > Weather Conditions'' from the menu, enabling ''Manually Configure Weather'' and clicking the ''Manual Configuration...'' button. | All other values are derived from these parameters.

When you want to have this default settings after starting FlightGear you have to take care about disabling METAR Data (look into the environment.xml file under metar-updates-... and set them to false). | ||
Of course, that's not the only way to configure BW. In fact, it supports the weather scenarios and can read METAR data, be it manually inserted or fetched on-the-fly. | Of course, that's not the only way to configure BW.
