  <div class="eI1">Description:</div>
  <div class="eI2">
This chart shows the relative humidity at Pa. In the forefield of a trough line 
as well as at and near fronts (Jets), warmer less dense air is forced to ascend.
As the ascending air cooles, the relative humidity increases, eventually resulting 
in condensation and the formation of clouds.This process is known as frontal lifting. <br>
High relative humidity at 700 hPa - equivalent to ca. 10000 ft a.s.l.  - indicates 
the areas of frontal lifting and thus the active zones of the current weather.

are a method of viewing data from an ensemble forecast.<br>
A meteorological variable e.g. pressure, temperature is drawn on a chart for a number of slightly different model runs from an ensemble. The model can then be stepped forward in time and the results compared and be used to gauge the amount of uncertainty in the forecast.<br>
If there is good agreement and the contours follow a recognisable pattern through the sequence then the confidence in the forecast can be high, conversely if the pattern is chaotic i.e resembling a plate of spaghetti then confidence will be low. Ensemble members will generally diverge over time and spaghetti plots are quick way to see when this happens.<br>
