QFE

QFE is calculated by adjusting the station level pressure for the difference between the barometer level and the aerodrome reference level, assuming International Standard Atmosphere(ISA) conditions. An Altimeter set to QFE will read zero when the aircraft is on the runway.

QNH

The pressure setting used by aircraft altimeters to give an indication above MSL. The QNH pressure calculation assumes a standard ICAO atmosphere.

Most AWS stations installed by the Bureau of Meteorology report pressure in QNH rather than standard MSLP. The difference between the two values can be as much as 3hPa for elevated locations.

Quasi-stationary front

A front that shows little or no horizontal movement. By convention, the term applies to a front this is moving at 5 knots or less. The slow horizontal motion combined with considerable vertical motion of the warm air, often gives rise to persistent and sometimes severe amounts of precipitation leading to local flooding.
