In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies.
Jan 14, 2020 · A low is an area where air pressure is lower than it is in the areas surrounding it. As a general rule of thumb, lows have a pressure of around 1,000 millibars (29.54 inches of mercury). Here is how these low-pressure systems form and how they affect the weather.
Oct 18, 2018 · 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. Thunderstorms, including...
Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms. Learn More. What are weather observations? How do we measure air temperature? How can we measure the wind?
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 the atmosphere where they meet.
What is low pressure? At times of low pressure, the air is usually rising. As the air rises, it cools, condenses and forms clouds. Areas of low pressure are known as depressions. Depressions occur when warm air meets cold air. The point where warm air meets cold air is called a front. Along the front, there is usually cloud and rainfall.
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...
