Weather scenario can consists of multiple time slices. Each time slice selected when creating a weather scenario will be displayed in its own window and includes its own definition of weather patterns. The beginning time of the time slice is displayed in the title bar of the window or in the main title bar if the window is maximized. Each time slice window allows the display of elements existing only in that particular time slice.

Every time slice in the weather scenario is contained in it's own window in the editor and each of these windows can be separately adjusted to view maps and different types of weather. Additionally changing the stratum allows to view the different wind and temperature values for a particular millibar level (i.e. by selecting 800 mb, the map will change to show wind speed and heading values selected for that range while in Wind view mode). Changing stratum does not effect the preview of pressure and precipitation. Only wind and temperature have different values at different stratum levels.

To preview weather, from the Wx window menu select View->Wx->”time slot”. This opens a list of weather views (Wind, Temperature, Pressure, and Precip). Select desired weather data to be viewed by repeating this step as necessary. To remove wx data from the display select View->Wx->None.

While Temperature or Pressure maps are toggled on, a right mouse click on any specific point on the map highlights a grid box and displays a context box with information such as temperature, pressure, and wind speed and direction for that particular cell.

The selection of a name and location for new a weather scenario is identical as in the new GSGT scenario (see Section 3.1.3, “Location and Name”) with the difference that weather scenario are saved in a different location. The location of weather scenarios is controlled by $WX_PATH environment variable.

To add a time slice to a weather scenario, use the arrows next to the time display near the lower left of the dialog to select the time, then click Add Time. more than one time slice can be added to the scenario. The weather settings at a selected time will remain constant until the next selected time is reached.

Wind values can be specified in several ways, such as speed and heading, U and V components, or X and Y components depending on type of the input format selected. Also different wind values can be specified at a different stratum levels.

Vector lines on the map represent wind direction and speed: longer lines representing higher speed values, shorter lines representing lower wind speeds.

Wind affects precipitation areas, causing them to drift and ‘morph’ much as real weather is affected by winds aloft. This only happen if winds are defined at the 1000mb level. Adding wind values to specific mb levels will also affect aircraft performance for those targets at a particular level causing them to slow down in a head wind and speed up with a tail wind, etc.

Temperature values can be specified in several temperature scales, such as Fahrenheit, Celsius or Kelvin. The default is Fahrenheit, to specify Celsius append C or for Kelvin append K after temperature value. Also different temperature values can be specified at a different stratum levels.

Pressure values are specified in millibars (mb) units of pressure. The "standard" sea level pressure is 1013.25 mb. Only a single pressure value can be specified for all stratum levels.

Precipitation values are specified in decibels (dbZ) units of precipitation and range from 0-99. This determines the intensity of the precipitation cell that was selected. The "standard" is 0 - no precipitation. Only a single precipitation value can be specified for all stratum levels. Also note that the precipitation editor only creates stationary precipitation.
