Feb 6, 2024 · Knowing how to read a weather map can help you understand the weather and know what to expect. For example, high pressure (H) areas will have clear skies, while low pressure (L) areas can be stormy. Blue "cold front" lines bring rain and wind in the direction the triangular marks point.

Dec 11, 2023 · Learn how to interpret various symbols and features on weather maps, such as wind, pressure, precipitation, fronts, clouds, and ocean currents. Meteomatics offers tools and resources to enhance weather data analysis and forecasting.
- Zulu, Z, and UTC Time on Weather Maps. One of the first coded pieces of data you might notice on a weather map is a 4-digit number followed by the letters "Z" or "UTC."
- High and Low Air Pressure Centers. The large letters (Blue H's and red L's) on weather maps indicate high- and low-pressure centers. They mark where the air pressure is highest and lowest relative to the surrounding air and are often labeled with a three- or four-digit pressure reading in millibars.
- Isobars. NOAA Weather Prediction Center. On some weather maps, you may notice lines surrounding and encircling the "highs" and "lows." These lines are called isobars because they connect areas where the air pressure is the same ("iso-" meaning equal and "-bar" meaning pressure).
- Weather Fronts and Features. Weather fronts appear as different colored lines that extend outward from the pressure center. They mark the boundary where two opposite air masses meet.
