what is difference between high pressure systems and low pressure systems?

Question

Please and Thank you

Answer 1

The components of storms are attracted to regions of low pressure. For this reason, heavy precipitation and overcast conditions are often associated with low-pressure systems. Due to the Coriolis effect, low-pressure systems often develop cyclonic properties: in the northern hemisphere, winds around the system move counterclockwise, and in the southern hemisphere they move clockwise. Low pressure systems, additionally, often become junctures of fronts.

Most of history's most powerful storms, such as the 1993 North American storm complex and all tropical cyclones, have been low-pressure cyclonic systems. Tornadoes invariantly have very strong local low-pressure systems at their vortices.

The lowest recorded non-tornadic barometric pressure was 869.96 millibars (25.69 inches of mercury), occurred in the Western Pacific during Typhoon Tip on 12 October 1979.

High pressure systems are associated with clear, cool weather . Around high-pressure systems, winds flow anticyclonically— that is, clockwise in the northern hemisphere, counterclockwise in the southern hemisphere.

In the northern winter, high-pressure systems (called Canadian highs or arctic air masses) often migrate to midlatitude regions such as the North American upper Midwest, New England, and northern Europe. These create cold snaps where unseasonably cold and sunny weather are observed. Cold snaps often follow winter warm spells, where temperatures may be as high as 10°C to 20°C (50-68 °F), and often happen suddenly. The most dramatic arctic cold snaps, observed in the central regions of North America involve temperature drops of 25°C (45°F) or more in a few hours.

Arctic highs, alone, rarely trigger precipitation because of the cloudless weather they produce. However, in combination with other weather-making systems, the cold air they bring can produce massive snowstorms.

Answer 2

A high pressure system is an area of relative pressure maximum that has diverging winds and a rotation opposite to the earth's rotation. Fair weather is typically associated with high pressure.

opposite for low pressure

Answer 3

High pressure systems are generally associated with good weather and winds blowing around them in a clockwise direction in the northern hemisphere and a counterclockwise direction in the southern hemisphere.

Low pressure systems are the opposite, associated with rain or snow and cloudy weather. The wind patterns are in the opposite direction of the high pressure systems.

Answer 4

High pressure brings clear, sunny sky. Low pressure brings clouds and storms.

Answer 5

amount of pressure being distributed.High pressure/more pressure,low pressure/less pressure.

Answer 6

about two inches of mercury.
