A surface weather analysis is a type of weather map that depicts positions for high and low-pressure areas, as well as various types of synoptic scale systems such as frontal zones. Isotherms can be drawn on these maps, which are lines of equal temperature.
An atmospheric reanalysis (also: meteorological reanalysis and climate reanalysis) is a meteorological and climate data assimilation project which aims to assimilate historical atmospheric observational data spanning an extended period, using a single consistent assimilation (or "analysis") scheme throughout.
[39] [40] [41] Compared with similar data from radiosondes, the satellite data has the advantage of global coverage, but at a lower accuracy and resolution. [42] Meteorological radar provide information on precipitation location and intensity, which can be used to estimate precipitation accumulations over time. [ 43 ]

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.
A surface weather analysis is a type of weather map which provides a view of weather elements at a specified time based on information from ground-based weather stations. . Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover onto a geographical map to help find synoptic scale features such as weather fro
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
A numerical weather model must accurately model both the seasonal cycle and (if finely resolved enough) the diurnal cycle. This output, however, adds no information content, since the same cycles are easily predicted from climatological data. Climatological cycles may be removed from both the model output and the "truth" data.
