low pressure often below 975 millibars
Tornadoes form from thunderstorms usually associated with mid-latitude low pressure systems, sometimes called frontal lows. They can also form with other systems such as hurricanes, though.
In the northern hemisphere, winds associated with a high-pressure system blow clockwise towards the center.
Tornadoes, especially strong tornadoes, are most often associated with a type of thunderstorm called a supercell.
Clouds are more likely to form when the air pressure is low. Low air pressure is associated with rising air, which cools and condenses to form clouds. High air pressure is typically associated with sinking air, which inhibits cloud formation.
Low pressure systems typically bring unsettled weather conditions, such as cloudy skies, precipitation (rain, snow, or storms), and sometimes strong winds. These systems are associated with inclement weather patterns due to the rising motion of air and atmospheric instability.
Both tornadoes and blizzards are dangerous storms the produce strong winds. Both are generally associated with low barometric pressure, as are nearly all storms.
A hurricane is associated with low air pressure.
A tornado has a center of low pressure.
hurricanes and blizzards
Blizzards can be predicted by finding the center of a low pressure system by looking at maps. They then identify areas of low pressure, wind flow patterns, temperatures, and the dew point.
Low pressure typically occurs during a blizzard. This is because blizzards are usually associated with strong low-pressure systems that bring cold air, strong winds, and heavy snowfall. The low pressure creates the atmospheric conditions necessary for a blizzard to form.
the type of precipitation that blizzards produce is snow(:
Cyclones and decreasing air pressure are associated with wind, clouds, and precipitation.
