      • It doesn’t look like European high pressure is going to go away any time soon and it could strengthen again for a while. So the wettest weather could return to northern and western areas of the UK, with a drier trend for southern and eastern regions. This should also mean that temperatures will be above average overall.

    On a weather chart, lines joining places with equal sea-level pressures are called isobars. Charts showing isobars are useful because they identify features such as anticyclones (areas of high pressure) and depressions (areas of low pressure).

    Areas of high and low pressure are caused by ascending and descending air. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface. In general, low pressure leads to unsettled weather conditions and high pressure leads to settled weather conditions.

    In an anticyclone (high pressure) the winds tend to be light and blow in a clockwise direction (in the northern hemisphere). Also, the air is descending, which reduces the formation of cloud and leads to light winds and settled weather conditions.

    In a depression (low pressure), air is rising and blows in an anticlockwise direction around the low (in the northern hemisphere). As it rises and cools, water vapour condenses to form clouds and perhaps precipitation. This is why the weather in a depression is often unsettled, there are usually weather fronts associated with depressions.

  7. Jan 24, 2020 · Accordingly, a common perception is that high-pressure always brings dry and fine weather with clear skies. The overcast and dreary conditions this week goes against this misconception. Weather forecasters often refer to these grey and drab skies under high-pressure as anticyclonic gloom.
