A popular type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Cloud codes are translated into symbols and plotted on these maps along with other meteorological data that are included in synoptic reports sent by professionally trained observers.
A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
Around 1950, a good surface prognostic chart was considered to be one whose isobars were in the correct location. [19] By 1957, it was proposed when isobars or height lines at the 500 hectopascals (15 inHg) pressure level in the atmosphere were being verified, that the degree of persistence should be considered so as to avoid getting bad ...
Smoke from the Park Fire in Northern California is expected to largely spare the Sacramento region, according to a National Weather Service forecast.
The direction of geostrophic flow is parallel to the isobars, with the high pressure to the right of the flow in the Northern Hemisphere, and the high pressure to the left in the Southern Hemisphere. The concept is familiar from weather maps, whose isobars show the direction of geostrophic winds. Geostrophic flows may be barotropic or ...

On the top right corner of the model for a surface weather map is the pressure, showing the last two integer digits of the pressure in millibars, or hectopascals, along with the first decimal. For instance, if the pressure at a certain location is 999.7 hPa, the pressure portion of the station model will read 997.
Small plots at various locations on the map, showing weather conditions at individual weather stations. Include details like: Temperature (in °C or °F). Dew point (a measure of humidity). Wind speed and direction (often represented by barbs). Atmospheric pressure (corrected to sea level). Cloud cover and precipitation. Wind Patterns:
