In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area.

2020年1月14日 · When you see a red capital letter "L" on a weather map, you're looking at a symbolic representation of a low-pressure area, also known as a "low." A low is an area where air pressure is lower than it is in the areas surrounding it.

2018年10月18日 · Quite simply, a low pressure area is a storm. Hurricanes and large-scale rain and snow events (blizzards and nor'easters) in the winter are examples of storms. …

These areas are called low pressure systems. Places where the air pressure is high, are called high pressure systems. A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in …

2023年12月18日 · Low-pressure systems are atmospheric zones where the air pressure is lower than that of the surrounding areas. When you hear low-pressure, think of “bad” weather. Low-pressure systems often create challenging conditions for pilots.

A low-pressure area is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. [1] The formation process of a low-pressure area is known as cyclogenesis. [2]

A low pressure area, or low for short, is a word used in meteorology (the study of weather) that means a place where the atmospheric pressure is lowest compared to the surrounding area. Coriolis effect causes winds to blow counter-clockwise in the northern hemisphere and clockwise in southern hemisphere .

2011年2月1日 · A low pressure area forms at the surface and a region of clouds forms at altitude. The air eventually stops rising and spreads north and south towards the Earth's poles. About 2000 miles from the equator, the air falls back to Earth's surface blowing towards the pole and back to …

Low pressure zones, also known as areas of low atmospheric pressure, are regions in the Earth’s atmosphere where the air pressure is relatively lower compared to the surrounding areas. These zones are characterized by ascending air currents and …

2020年2月4日 · A low-pressure system, also called a depression, is an area where the atmospheric pressure is lower than that of the area surrounding it. Lows are usually associated with high winds, warm air, and atmospheric lifting.
