How is station plot information used?

Meteorologists use the station plots to draw lines of constant pressure (isobars), temperature (isotherms), and dew point (isodrosotherms) to achieve an understanding of the current state of the atmosphere. This knowledge ultimately leads to better weather forecasts and warnings.

How do you measure humidity in a station model?

Once you have the saturation vapor pressure and the actual vapor pressure, relative humidity can be computed by dividing the actual vapor pressure by the saturation vapor pressure and then multiplying by 100 to convert the quantity to a percent.
