11 Facts About Weather fronts

For instance, cold Weather fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded by squall lines, while warm Weather fronts are usually preceded by stratiform precipitation and fog.

Some Weather fronts produce no precipitation and little cloudiness, although there is invariably always a wind shift.

Cold Weather fronts generally move from west to east, whereas warm Weather fronts move poleward, although any direction is possible.

Occluded Weather fronts are a hybrid merge of the two, and stationary Weather fronts are stalled in their motion.

Cold Weather fronts often bring rain, and sometimes heavy thunderstorms as well.

Cold fronts can produce sharper and more intense changes in weather and move at a rate that is up to twice as fast as warm fronts, since cold air is more dense than warm air, lifting as well as pushing the warm air preceding the boundary.

Warm Weather fronts are at the leading edge of a homogeneous advancing warm air mass, which is located on the equatorward edge of the gradient in isotherms, and lie within broader troughs of low pressure than cold Weather fronts.

Occluded fronts are indicated on a weather map by a purple line with alternating half-circles and triangles pointing in direction of travel.

Stationary fronts are marked on weather maps with alternating red half-circles and blue spikes pointing opposite to each other, indicating no significant movement.

When stationary Weather fronts become smaller in scale and stabilizes in temperature, degenerating to a narrow zone where wind direction changes significantly over a relatively short distance, they become known as shearlines.

Although, not all Weather fronts produce precipitation or even clouds because moisture must be present in the air mass which is being lifted.
