Understanding Weather Systems

Atmospheric activity creates weather systems that generate the daily weather conditions we experience. Several factors, such as the movement of air masses and the existence of high and low pressure, influence the changeable weather in the UK.

The position of the Jet Stream leads to the development of low- or high-pressure systems. When the atmosphere is unstable low-pressure systems develop, which includes fronts, cyclones, and depressions. Frontal systems occur often in the UK, bringing cloudy, wet, and windy conditions.

The Atlantic Ocean also plays an important role in our weather, westerly and south-westerly winds bring warm moist air, giving us milder temperatures, especially in western coastal areas. Remnants of Atlantic storms can bring heavy rain and high winds; if met with colder air masses it is possible for the storms’ remains to produce snow during the winter. In the winter months the UK experiences polar maritime air which brings colder temperatures and moist air, resulting in a greater potential for rain and snow. Other air masses also lead to varying temperatures and conditions. Although we experience cold spells, our winters are not as extreme compared to other locations in the northern hemisphere.

When the atmosphere is stable, high-pressure builds, and conditions become more settled and drier. During the winter, blocking high pressure, an area of high pressure that stays for an extended period and prevents low pressure systems from moving in, brings cold and dry conditions which leads to overnight frost, and morning fog.

Weather systems drive our daily conditions. Monitoring forecasts and awareness of potential winter hazards different systems can bring, helps Ice Watch deliver an effective winter maintenance service.
