The warm air is moist due to water evaporating from the land/ocean. It is low pressure because warm air is less dense, and rises, creating an area of low pressure.

What weather do warm moist air masses bring?
low pressure
Why does barametric pressure drop when hurricane approaches?
Hurricanes are driven by low pressure. Low pressure pulls in warm, moist air, leading to convergence in the lower atmosphere, this causes thunderstorms to spring up, which lower the pressure further and pull in more warm, moist air. These processes help to sustain one another in a hurricane.
Why is a hurricane stronger with less pressuere?
Hurricanes feed on warm, moist air that they pull in. The lower the pressure, the more air they can pull in. Also, the lower pressure creates a larger force on the air, causing it to go faster. As more warm moist air gets pulled in the convection intensifies, causing the pressure to drop even further.
Does cool dry air meeting warm moist air causes a tornado?
Not directly. Cool, dry air meeting warm, moist air creates what is called a front. Fronts such as this frequently cause showers and thunderstorms. If other conditions are right, most importantly the speed and direction of the wind at different altitudes, then some of the thunderstorms will be able to produce tornadoes.
Why must winds converge for hurricane?
Hurricanes are powered by convection as warm, moist air rises. This creates low pressure that draws in warm air to continue to feed the hurricane.
Is cool dry air meeting warm a cause of tornadoes?
When cool dry air meets warm moist air the result is thunderstorms. If other conditions are present those storms scan produce tornadoes.
What updrafts of warm moist air result in tall clouds called?
Cumulus clouds is an resault of updraft of warm,moist air in tall clouds.
What weather do warm moist air masses bring?
low pressure
Which air pressure system is generally associated with warm moist air?
Choices; low pressure, changing pressure, high pressure, no pressure.
If the temperature increases and the barometric pressure falls then what is likely occurring?
Warm, moist air mass is approaching as a warm front
What of following causes tornadoes?
wind shear- earth science
As warm moist air moves into a region barometric pressure readings in the region will generally?
Decrease
Why does barametric pressure drop when hurricane approaches?

When warm air moves upward in a thunderhead it creates a zone of?
Warm moist air over the equator creates a zone of convection.
When warm moist air comkes in contact with cool air what happens?
Usually rain showers or thunderstorms result.
When warm and moist winds blow over snow-covered ground what is most likely to result?
advection fog
