Atmospheric lift caused by low-level wind convergence into the surface low brings clouds and potentially precipitation. The low-pressure area's cloudy skies act to minimize diurnal temperature variation. Since clouds reflect sunlight, incoming shortwave solar radiation is less, which causes lower temperatures during the day. At night, the absorptive effect of clouds on outgoing longwave radiation, such as heat energy from the surface, allows for warmer diurnal low temperatures in all seasons. The stronger the area of low pressure, the stronger the winds experienced in its vicinity. Around the world, low-pressure systems are most frequently located over the Tibetan Plateau and in the lee of the Rocky mountains. In Europe—in particular, the United Kingdom and the Netherlands—recurring low-pressure weather systems are typically known as depressions. The lowest recorded non-tornadic barometric pressure was , occurring in the Western Pacific during Typhoon Tip on 12 October 1979.
