The numeric pressure value adjusts automatically as theforecast station reads changes in air pressure. Since this number is absolute pressure, it may not be the sameas a local reporting station that reads in relative pressure.Note: The number cannot be calibrated. Absolute Pressure is measured in a vacuum without the influences of terrain, weather, water, foliage andelevation. The air pressure it would be consistent at every elevation and decrease as it went higher. Relative Pressure is a combination of air pressure and altitude. Relative air pressure will make readings inlocal areas relative to each other to allow for proper forecasting.TEMPALERTSETCH |
