GFS (15 days) - Current model charts of parameter "Mean Sea Level Pressure" for map "Texas"
This is in contrast to mean sea-level pressure, which involves the extrapolation of pressure to sea level for locations above or below sea level. The average pressure at mean sea level in the International Standard Atmosphere is 1,013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury.
Global maps of air pressure. The maps show the global distribution of the monthly means respectively the anomalies of the air pressure reduced to sea level. In areas with little data, especially over the oceans, there are hardly any measurements that allow direct analyses from observations.
11 gru 2023 · This map shows the sea-level pressures for various locations over the contiguous U.S. The values are in whole millibars. Objective. Using a black colored pencil, lightly draw lines connecting identical values of sea-level pressure. Remember, these lines, called isobars, do not cross each other.
18 gru 2023 · At sea level, standard air pressure in millibars is 1013.2. Weather maps showing the pressure at the surface are drawn using millibars. Although the changes are usually too slow to observe directly, air pressure is almost always changing.
