The “Pressure Trend 3h” product provides forecasts every three hours for the next seven days, indicating variations in atmospheric pressure at sea level in hectopascals (hPa) over three-hour intervals. This index is essential for identifying short-term pressure trends, helping to predict rapid changes in weather conditions.
