What are weather Maps ?
A weather map displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes

First Weather Map
The earliest weather charts were made by collecting synchronous weather reports by mail. However, it was not until 1816 that German physicist Heinrich Wilhelm Brandes created the first weather maps, which were hand drawn and reconstructed from data collected in 1783. The first telegraphic collection of synoptic meteorological reports and their mapping for forecasting was accomplished by Urbain-J.-J. Le Verrier during the mid-1800s.
Different types of Weather Maps
H
- Pressure Maps
- Station Model Maps
- Tempearute Maps
- Streamline Maps
- Climate Maps
Temperature Maps
Temperature maps show the current temperature in either a color scale or by temperatures in numbers on the map surface. Temperature maps are one of the most common types of weather maps and are often comine with the cloud cover and precipitation to give a basic weather for newspapers and programs.
Station Model Maps
Station Model maps show the weather condtions at a certain weather station. They report on all kinds of weather condtions such as temperature, humidity, air pressure, cloud cover or wind spead.
Streamline Maps
Streamline maps show the wind patterns in particular areas. These maps use isobaric pressure readings as part of the process but combine and convert the data into much more usefu images of actual wind parrtens rather than just a pressure reading at different points.
Weather Map Symbols

Standard symbols on weather maps show areas of high and low pressure, fronts, types of precipitation, and temperatures of major cities.

Why are Weather Maps important?
- Weather maps help create accurate weather predictions so that we can plan our day-to-day activities.
- Weather forecasting helps us to make more informed daily decisions, and may even help keep us out of danger.
- Modern weather forecasting involves a combination of computer models, observation, and a knowledge of trends and patterns.
