The “Sea Level Pressure” product provides forecasts every three hours for the next seven days, presenting atmospheric pressure at sea level in hectopascals (hPa). Sea level pressure is a crucial indicator for weather analysis, as its variations are directly related to the formation and movement of meteorological systems.
- Low pressure: Often signifies the presence of low-pressure systems, which frequently bring unstable weather, including rain and storms.
- High pressure: Generally associated with more stable and dry atmospheric conditions.
Understanding pressure trends helps meteorologists, navigators, and aviation professionals anticipate weather patterns and make informed operational decisions.
