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.
Integrated Surface Database (ISD) is global database compiled by the National Oceanic and Atmospheric Administration (NOAA) and the National Centers for Environmental Information (NCEI) comprising hourly and synoptic surface observations compiled globally from ~35,500 weather stations; it is updated, automatically, hourly.
A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.
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 fronts. The first weather maps in the 19th century were drawn well after the fact to help devise a theory on storm systems. [3]
NOAA: Synoptic scale weather analysis Synoptic scale meteorology predicts atmospheric changes at scales up to 1000 km and 10 5 sec (28 days), in time and space. At the synoptic scale, the Coriolis acceleration acting on moving air masses (outside of the tropics) plays a dominant role in predictions.
The National Oceanic and Atmospheric Administration released its seasonal outlook for the winter months of 2024-25, which predicts the U.S. will slowly transition into a La Niña pattern that ...
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.
