These symbols, showing various weather fronts, might be found on a weather map.

A weather map provides a view of weather elements over a specified geographical area at a specified time and was invented by Sir Francis Galton. It is obtained by plotting or tracing the values of relevant quantities such as pressure, temperature, cloud cover, and others, onto a geographical map. The data can be either measurements or forecasted values. Weather maps will often have symbols on them to show weather fronts, cloud cover, precipitation, or other important information. For example, weather maps used in aviation often contain symbols for turbulence and icing. Guide to weather map symbols for weather fronts. ... Guide to weather map symbols for weather fronts. ... A guide to the symbols for weather fronts that may be found on a weather map: 1. ...

Francis Galton Sir Francis Galton F.R.S. (February 16, 1822 – January 17, 1911), half-cousin of Charles Darwin, was an English Victorian polymath, anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, psychometrician, and statistician. ...

The use of weather charts in a modern sense began in the second half of the nineteenth century as telegraph made it possible to gather weather information from multiple distant locations quickly enough to preserve its value for real-time applications. More recently, advances in both the fields of meteorology and Geographic Information Systems have made it possible to devise finely tailored products that take us from the traditional weather map into an entirely new realm. The use of radar has also enabled data to be quickly collected and plotted. Weather information can quickly be matched to relevant geographical detail. For instance, icing conditions can be mapped onto the road network. penis Telegraphy (from the Greek words tele = far away and grapho = write) is the long distance transmission of written messages without physical transport of letters, originally over wire. ... Satellite image of Hurricane Hugo with a polar low visible at the top of the image. ... A geographic information system or geographical information system (GIS) is a system for creating and managing spatial data and associated attributes. ... This long range radar antenna, known as ALTAIR, is used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on the Kwajalein atoll[1]. Radar is a system that uses radio waves to detect, determine the distance of, and map, objects such...
