Why are droughts usually associated with high-pressure systems?
Wiki User
∙ 11y ago
High pressure systems contain less water vapor than low pressure systems, so are less likely to bring rain, less likely to provide shade with clouds, and more likely to cause evaporation of the surface water that might already be there.
High Pressure systems are dry and dense and cold air above has a tendency to sink and inhibit the upward movement of air. Thus, cloud formation does not occur, and droughts (periods of less rain) occur.

What are high pressure systems usually not associated with?
High pressure systems are usually not associated with changeable weather.
Why are low pressure systems usually associated with cold fronts?
A cold front is usually associated with low pressure systems because it is dense or heavier than warm air and descends downwards.
Could the atmospheric conditions that cause a drought also cause the formation of a supercell?
Not usually. Supercells usually require moist, unstable air while droughts are more often associated with dry, stable air.
What happens in a low pressure system?
Low pressure systems are usually associated with stormy weather and rain.
Is high pressure systems associated with storms and precipitation?
No, High Pressure usually keeps the weather nice. Low pressure is the one that makes the storms.
What are pressure systems are usually associated with?
High pressure systems are usually not associated with changeable weather.
What are high pressure systems usually not associated with?
High pressure systems are usually not associated with changeable weather.
What are high-pressure systems usually associated with?
High pressure systems are usually not associated with changeable weather.
What are usually associated with high pressure?

When do droughts occur in America?

What are low pressure systems usually associated with?
K12 OHVA answer: cloudy, wet weather

Not usually. Supercells usually require moist, unstable air while droughts are more often associated with dry, stable air.
Where do droughts usually appear?
in dry areas
What type of system is associated with tornadoes?
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.
What kind of weather does low air presure usually bring?
Storms are associated with low pressure weather systems.
