The map shows the weather forecast at an altitude of 1.5 kilometers, or 850 hectopascals (hPa), from the WRF-ROMS model. Users can view two types of data: 1) atmospheric pressure (hPa) and 2) wind direction and speed (km/h). Data at this level are important for weather forecasting, as it is used to track the movement of air pressure, moisture transport, and analyze monsoon troughs, which directly affect surface weather and rainfall.
