低气压 Low-pressure area

(重定向自Low Pressure)
Una borrasca gira en la costa sudeste de Islandia, ilustrando la máxima
A clockwise spinning low pressure area or cyclone off southern Australia. The center of the spiral-shaped cloud system is also the center of a low, and usually is where the pressure's lowest.
This depiction of the Hadley cell shows the process which sustains low-pressure areas.  Diverging winds aloft allow for lower pressure and convergence at the Earth's surface, which leads to upward motion.

低压区英语:Low pressure area,符号为L)是大气中气压较邻近地区为低的地带。一般都是成螺旋状,是为气旋。在北半球低气压区域内的空气作逆时针方向旋转,在南半球则顺时针方向。偶尔也有一连串低压区连在一起,称为「低压槽」,因该区的大气压力比其两旁为低,所以称为槽,是为槽线取其陷下的意思。低压区一般都伴着云,或会有风、雨(通常雨势较大并夹杂着狂风雷暴)。

A low-pressure area, low or depression, is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence which occur in the upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis. Within the field of meteorology, atmospheric divergence aloft occurs in two areas. The first area is on the east side of upper troughs which form half of a Rossby wave within the Westerlies (a trough with large wavelength which extends through the troposphere). A second area of wind divergence aloft occurs ahead of embedded shortwave troughs which are of smaller wavelength. Diverging winds aloft ahead of these troughs cause atmospheric lift within the troposphere below, which lowers surface pressures as upward motion partially counteracts the force of gravity.
