Dataset: Mean Sea Level Pressure


Description

The mean sea level pressure (MSLP) isobars show lines of equal atmospheric pressure (hPa) that have been generated from the numerical prediction model, APS2 Australian Community Climate Earth-System Simulator (ACCESS) for greater Australia. The model incorporates equations that represent the motion of the atmosphere and its associated physics. The model is run four times a day at 0UTC, 06UTC, 12UTC and 18UTC and produces hourly forecasts from 0 hours (base time) to 72 hours. The isobars are derived from a 0.11 degree grid. As there is no manual input, the products generated will differ from the official forecasts, especially in the vicinity of weather fronts, tropical cyclones or when significant late-breaking observations have become available to forecasters. The units are hPa.
