- Pressure Maps. Pressure maps are measured in millibars, and tell the reader where there is high atmospheric pressure, as compared to average sea-level pressure, and where there is low atmospheric pressure.
- Station Model Maps. Station-model maps show the weather conditions at a particular weather station. They report on all kinds of weather conditions, such as temperature, humidity, air pressure, cloud cover or wind speed.
- Aviation Maps. Aviation maps are live weather maps specifically containing information necessary for the safe flight or aircraft. Information such as wind speed and direction, dew point readings, flight advisory information, temporary flight restrictions, cool and warm weather fronts and icing areas are all displayed on aviation 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 often combine with cloud cover and precipitation to give a basic weather indication for newspapers and news programs.
Apr 27, 2024 · The current surface synoptic weather map is the type of map commonly used by meteorologists. This map shows the positions of high- and low-pressure systems, surface weather plots, and the locations of fronts. It provides a comprehensive view of the current weather conditions over a large area, aiding meteorologists in their analysis and ...

Most of these maps can be placed into one of two groups: 1) reference maps; and, 2) thematic maps. Reference maps show the location of geographic boundaries, physical features of Earth, or cultural features such as places, cities, and roads. Political maps, physical maps, road maps, topographic maps, time zone maps, geologic maps, and zip code ...

Earth’s atmosphere is a jacket of gases that surrounds the planet. Although it seems like these gases could easily float away into space, gravity is constantly pulling the atmosphere toward Earth’s surface. The force with which our atmosphere pushes down on a specific location on Earth is called atmospheric pressure. Atmospheric pressure is mainly ...
A high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. A low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air. In general, areas that experience high atmospheric pressure also experience fair weather. Low pressure systems can cause the formation of clo...
From high above Earth, satellites such as GOES-16 keep an eye on the weather brought by low pressure systems. The red “L” on the map above indicates a low pressure system in the Tennessee Valley region. In the video below from GOES-16, you can see what that same low pressure system looks like from a weather satellite.
A warm frontis the transition area where a mass of warm air moves to replace a mass of cold air. On a weather map, a warm front is usually drawn using a solid red line with half circles pointing in the direction of the cold air that will be replaced. Warm fronts usually move from southwest to northeast. A warm front can initially bring some rain, f...
GOES-16 and other weather satellites are also on the lookout for cold fronts and warm fronts and the weather they produce. Below, you can see the comparison of a cold front on a forecast map and a cold front in a satellite image.
Information from weather satellites, such as the GOES-R series and JPSSwill help improve our understanding of Earth’s weather. For example, the GOES-R series provides information about atmospheric water vapor and cloud height right now. This can help meteorologists monitor and track severe weather events, such as storms and hurricanes as they happe...
National Weather Maps. Surface Analysis. Highs, lows, fronts, troughs, outflow boundaries, squall lines, drylines for much of North America, the Western Atlantic and Eastern Pacific oceans, and the Gulf of Mexico.
2. However, the weather map generally consist of the following basic elements, so keep your attention on them, while reading the map: colors, special symbols, numbers, letters or phrases, lines, different interactive elements. 3. Weather maps come in different types depending on the information (weather forecast) that they show.
Jul 21, 2023 · Larger open areas usually indicate these areas with the lines spaced far apart. The spacing between the lines also clearly shows you how steep the gradient, or how quick the change in pressure is. The closer the lines are spaced together, the stronger the wind speed in the area will be.
