A high pressure system has a weaker horizontal pressure gradient than a low pressure system, which means the atmospheric pressure varies widely in a low pressure system and doesn't vary much in a high pressure system. The wind speed depends on the strength of the horizontal pressure gradient.
On a meteorological map, the horizontal pressure gradient is marked with isobars, which are lines with match the points with the same atmospheric pressure. A high pressure system is characterized by widely spaced isobars while low pressure systems are noted by tightened close isobars.
A high pressure system may have an air pressure of 1028 hPa in his core and 1013 hPa in its periphery: the air pressure varies about 16 hPa. A low pressure system may have an air pressure of 987 hPa in its core and 1013 in its periphery : the air pressure varies about 26 hPa. So, the winds will be very light and even non-existent in a high pressure system while the winds will be very strong and even turbulent in a low pressure system.

Why do high and low pressure systems rotate?
wind
The movement of air from areas of high pressure to areas of low pressure?
It's wind. and contrary to popular belief, the air movement is actually like that of a vacuum cleaner, low pressure areas suck from high rather than high blowing to low. We should say the wind sucks, not the wind blows.
How high pressure systems clear skies?
Air always moves from areas of high pressure to areas of low pressure. Therefore, air moves away from high pressure systems, thus creating wind which pushes clouds away. This results in a clear sky at the high pressure system.
What is Buys Ballot's law?
The law states how the location of pressure systems can be deduced from the wind direction in the Northern Hemisphere. "If one stands with his back to the wind, atmospheric pressure is higher to his right and lower to his left" (restated: a high pressure system may be to your right, or a low pressure system to your left). This is because in the Northern Hemisphere, the rotation of high pressure systems is clockwise and in low pressure systems, it is counterclockwise.
Are hurricanes low pressure or high pressure?
Hurricanes are low pressure systems.
Why do high and low pressure systems rotate?
wind
Does wind come from weather?
Wind is caused by variation in air pressure. Wind blows from regions of high pressure to regions of low pressure. Generally, high pressure systems bring good weather, while low pressure systems tend to bring stormy weather.
How does wind move between pressure systems?
from areas of high pressure to areas of low pressure
Why can't there be wind without the sun?
The sun heats the air which causes high and low pressure systems which results in wind. high to low.
The movement of air from areas of high pressure to areas of low pressure?
It's wind. and contrary to popular belief, the air movement is actually like that of a vacuum cleaner, low pressure areas suck from high rather than high blowing to low. We should say the wind sucks, not the wind blows.
Where does the wind in a high pressure system turn?
Remember this, high pressure systems usually go outwards, into low pressure systems in order to create an equilibrium. In the northern hemisphere, the high pressure wind turns right due to the coriolis effect, and opposite in the south.
How high pressure systems clear skies?
Air always moves from areas of high pressure to areas of low pressure. Therefore, air moves away from high pressure systems, thus creating wind which pushes clouds away. This results in a clear sky at the high pressure system.
Do humans get headaches from high and low pressure systems?
Humans do not get headaches from high and low pressure systems.

Does wind move from high to low or low to high pressure?
High to Low.
Are hurricanes low pressure or high pressure?
Hurricanes are low pressure systems.
How is wind moved?
Wind is moved by a high pressure turning into a low pressure.
