A weather front is a boundary between two air masses. It can be thought of like the frontline in a battle, where the warm air represents one side and its 'enemy,' the cold air, the other side. Across a front, there can be large variations in temperature, as warm air comes into contact with cooler air. The difference in temperature can indicate the ...
The UK has unique weather because we are an island nation, with a large ocean to the west of us, a large landmass to the east of us and because of our position north of the equator. These factors mean that we experience a large number of frontal systems and their associated weather. Most of the frontal systems that affect the UK are formed out over...
A cold front is symbolised on a weather map as a line with triangles. The triangles can be thought of as icicles. Cold fronts are often coloured blue. The presence of a cold front means that cold air is advancing and pushing underneath warmer air. This is because the cold air is 'heavier,' or denser, than the warm air. Cold air is thus replacing wa...
A warm front is symbolised on a weather map as a line with semicircles. The semicircles can be thought of as half suns. Warm fronts are often coloured red. The presence of a warm front means that warm air is advancing and rising over cold air. This is because warm air is 'lighter,' or less dense than cold air. Warm air is replacing cooler air at th...
An occluded front is symbolised on a weather map as a line with both semicircles and triangles. They are often coloured purple. These are slightly more complex than cold or warm fronts. The word occluded means 'hidden' and an occlusion occurs when the cold front 'catches up' with the warm front. The warm air is then lifted from the surface, and the...
Aug 23, 2021 · So the next time you see a synoptic weather chart, you’ll be able to look for areas of high (anticyclone) or low pressure (depression), check out the wind speed and direction and find out whether it’s a warm or a cold front heading our way.

- Wind speed and direction. The surface wind direction is indicated on the station plot by an arrow flying with the wind. Direction is measured in degrees from true North.
- Air temperature. Air temperature is plotted to the nearest whole degree Celsius, i.e. 23 would indicate 23 degrees Celsius.
- Dew point temperature. Dew point temperature is plotted to the nearest whole degree Celsius, i.e. 18 would indicate a dew point of 18 degrees Celsius.
- Pressure. Pressure is recorded in millibars and tenths and the last three digits are plotted. Therefore 1003.1 would be plotted as 031 and 987.1 would be plotted as 871.
Pressure levels and weather fronts. An actual analysis chart is issued along with forecast charts out to five days ahead. These are updated every 12 hours around 0730 and 1930, with the...
3. Weather fronts. These define the boundaries between different air masses, typically bringing cloud, precipitation and changes in temperature and humidity. They’re depicted through coloured lines with shapes on one side, with the side featuring the shapes showing the direction of movement.
