A map legend is a side table or box on a map that shows the meaning of the symbols, shapes, and colors used on the map. They mark where the air pressure is. The large letters (Blue H's and red L's) on weather maps indicate high- and low-pressure centers. Atmospheric pressure is measured with an instrument on the ground called a barometer, and these measurements are collected at many locations across the U.S. by  . What it Means on the Weather Map Low pressure systems—like this one in the Tennessee valley—can cause the formation of clouds and storms. A high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. On weather maps, these readings are represented as a blue “H” for high pressure or a red “L” for low pressure. A high pressure system is a dense air mass that is usually cooler and drier than the surrounding air.

Surface analysis from April 7, The map below has isobars, or lines of constant pressure, analyzed, which shows the locations of high and low pressure systems. The plotted symbol characterizes the change in pressure according to the below chart. Plotted to the nearest tenth of a millibar. When isobars enclose an area of high pressure this is called a High or anticyclone and its centre is labelled on a weather map by an 'H'. Google's satellite imagery, aerial photography and panoramic street views now give us front-row seats to some of the most mysterious, bizarre and interesting people, places and things around the globe. Blue "cold front" lines bring rain and wind in the  . For example, high pressure (H) areas will have clear skies, while low pressure (L) areas can be stormy. Part 3 Interpreting the Types of Fronts 1. They are represented on a weather map as isobars with an "H" in the middle isobar and arrows showing which direction the wind is flowing (clockwise in Northern Hemisphere, counterclockwise in the Southern Hemisphere). Like cyclones, they can also be shown with radar imagery. A high-pressure area is caused by atmospheric air under increasing pressure which drops towards the land surface, while a low-pressure area is characterized by reducing the pressure of air that goes upwards. Letter 'H' in blue signifies a high-pressure area, while the letter 'L' in red represents a low-pressure area. Learn about some fun ways to use Google Maps satellite. A  .

On the first map above, the Lows are in red, and the Highs are. Reading weather maps · High- and · Low-pressure centers are indicated with H and L, respectively. For example, an H may represent high pressure, implying good. Surface weather analyses have special symbols which show frontal systems, cloud cover, precipitation, or other important information. In this example, the pressure was steady then fell (lowered) becoming millibars LOWER than it was three hours ago. Pressure lower than three hours ago. This number and symbol tell how much the pressure has changed (in tenths of millibars) in the past three hours and the trend in the change of the pressure during that same period.
