What do synoptic charts tell us?
A synoptic chart is any map that summarises atmospheric conditions (temperature , precipitation , wind speed and direction, atmospheric pressure and cloud coverage) over a wide area at a given time. Weather symbols can seem confusing until you look for the patterns.
What are the synoptic chart symbols?
It displays information on temperature, precipitation, wind speed and direction, atmospheric pressure and cloud coverage, all observed from many different weather stations, aeroplanes, balloons and satellites.
What is a synoptic chart and how do you read it?
A synoptic chart is the scientific term for a weather map. Synoptic charts provide information on the distribution, movement and patterns of air pressure, rainfall, wind and temperature. This information is conveyed using symbols, which are explained in a legend.
What do all the lines mean on a synoptic chart?
The circular lines you see on the chart are isobars, which join areas of the same barometric pressure. The pressure pattern is important because we can use it to tell us where the wind is coming from and how strong it is. It also shows areas of high and low pressure.
What are the lines on a synoptic chart called?
The circular lines you see on the chart are isobars, which join areas of the same barometric pressure. The pressure pattern is important because we can use it to tell us where the wind is coming from and how strong it is.
How do you read cloud cover on a weather map?
Detailed maps show the cloud cover at reporting stations with coded circles. An open circle means that the sky is clear, while a filled circle means conditions are overcast.
How do you read wind direction?
Wind direction is defined as the direction the wind is coming from. If you stand so that the wind is blowing directly into your face, the direction you are facing names the wind. That’s why a north wind generally brings colder weather temperatures to Chicago and a south wind implies a warmup.
Why do you need to know how do you interpret a synoptic chart?
Synoptic charts provide information on the distribution, movement and patterns of air pressure, rainfall, wind and temperature. This information is conveyed using symbols, which are explained in a legend. Synoptic charts are used to report on the current weather and to predict future weather patterns.
What do you need to know about a synoptic chart?
Isobars give you a good indication of what you need to know about air pressure. Synoptic charts have a few shapes you need to identify, namely lines, triangles, and half-circles. These shapes are known as fronts. If you see a cold weather front, it means there is a change in the air mass. A cold one now replaces the warmer air.
What are the lines on a synoptic weather chart?
Cold fronts and warm fronts. Also on a synoptic chart are the lines, triangles and semi-circles representing ‘fronts’. With the atmosphere trying to balance temperature, pressure and wind there are different sorts of air, known as air masses, circulating around the Earth.
What are the colors of a synoptic map?
Warm air is represented by a reddish color scheme, while colder air uses bluish colors. When you look at a synoptic map, you can see either a red or blue line. A warm front uses a red line with red half-circles, while cold fronts use a blue line with blue triangles.
How are isobars and cold fronts related in a synoptic chart?
Specifically, isobars indicate air pressure, while warm and cold fronts use their respective colors. Once you can read a synoptic chart, you can use the information to make informed decisions. For example, if you expect high winds in the future, you might want to bring warm clothing.
