Modern Weather Prediction Meteorologists use a process called numerical weather prediction to create forecasts by inputting current conditions — which they call the “nowcast” — into computer models. There are many different types of maps that attempt to represent specific things. _____ 4. They can depict information from computer models or from human observations. The science of weather is called meteorology. How to Read a Weather Map. Next lest find out about stationary fronts. WEATHER MAPS Weather maps, also called synoptic maps, simply and graphically depict meteorological conditions in the atmosphere from a spatial perspective. Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy.
