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.
A col, also called saddle point or neutral point, is in meteorology, the point of intersection of a trough and a ridge in the pressure pattern of a weather map. It takes the form of a saddle where the air pressure is relatively higher than that of the low-pressure regions, but lower than that of the anticyclonic zones. [1]
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 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. [2] Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover ...
Station model as used in the United States plotted on surface weather analyses. In meteorology, station models are symbolic illustrations showing the weather occurring at a given reporting station. Meteorologists created the station model to fit a number of weather elements into a small space on weather maps.
The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong [1] and Fiji, [2] it is represented by a bold line extended from a low pressure center [3] or between two low pressure centers; [4] in Macau [5] and Australia, [6] it is a
A surface weather analysis is a special type of weather map which provides a top view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. [6] Weather maps are created by detecting, plotting and tracing the values of relevant quantities such as sea-level pressure, temperature ...
Example of a Stüve diagram. A Stüve diagram is one type of thermodynamic diagram commonly used in weather analysis and forecasting. [1]This diagram has a simplicity in that it uses straight lines for the three primary variables: pressure, temperature and potential temperature.
