Weather Mapping - History, Data Collection And Transmission, Constructing The Weather Map, The Daily Weather Map
conditions process
Weather mapping is the process of representing existing weather patterns and their future development and movement on a map. The process is only possible if two conditions are met. First, current weather conditions must be available at a number of relatively widely distributed stations. Second, reports of those conditions must be transmitted to a central collecting station within a short time period.

Many different kinds of weather maps exist. Synoptic maps show current weather conditions, while prognostic maps show weather predictions for some time in the future. Some weather maps are complex and contain a great deal of detailed information. Others are simpler and provide only general patterns and trends. Maps can be sub-divided into those that summarize weather close to Earth's surfac…
The weather map that appears in daily newspapers can be used to predict with some degree of accuracy conditions in the next few days. It usually does not include as much station information as the more detailed maps described above. Instead the major features of the daily weather map include isobars and high and low pressure areas. Isobars connect locations with the same barometric pressure. The p…
