"Warm air tends to have low pressure. Warm air molecules are more active and thus need more space to move around, thus being less dense." This is true with air aloft. However the surface air. which is the air you feel has the opposite effect. cold air is at a higher pressure than warm air at the surface creating a cycle. This also explains how sea breezes and land breezes form.
I am confused. The air flows from the equator to the North pole in the Northern hemisphere.
Some posts say the air pressure at the North Pole is very high because the heat is low and the air particles become closer when cold and their density increase . The air gets heavier and the pressure on the surface gets bigger. The north Pole is an area of High Pressure according to this model.
At the Equator is is hotter, and hot air rises so the weight of the air pressing on the surface is reduced reduces the Air Pressure.
This means the Equator must be la low pressure area.
People claim air flows from an area of high pressure to a lower one which contradicts what really happens.
It would make sense if hot air traveled to a colder area. That is why we have double glazing!
Some claim the transfer of atmosphere is due to diffusion. Again this would suggest that air would go from the North Pole to the Equator!
Could someone help me where I am getting confused? It would be appreciated.
Air pressure at the equator is low due to more humidity.
Proximity to the equator has no significant impact on air pressure. Elevation above sea level does.

Horse Latitudes
The subtropical high pressure regions are centered at approximately 30 degrees north and south latitude.
No, it's a high pressure region.From wikipedia-Horse Latitudes or Subtropical High are subtropical latitudes between 30 and 35 degrees both north and south. This region, under a ridge of high pressure called the subtropical high, is an area which receives little precipitation and has variable winds mixed with calm.

these are areas of sinking air and average in positions around 30 degrees N latitude and 30 degrees S latitude. This the subtropical high pressure belt. Sometimes called the horse latitudes.
pressure belts
The uneven heating of the earth produces pressure belts. these belts occur at about every 30 degrees latitude. The rotation of the Earth flings the bulk of the air creating an area of low pressure belt in this region.

The 30 degree latitude area is at the high pressure region developed by the sinking air from the Hadley Cell created by the low pressure rising air at the equator. Winds move from high to low pressure areas. The doldrums are located at the equator, this is a low pressure area. When the air sinks at the 30 degree latitude air moves away from the 30 toward the equator and 60 degree latitudes. Since air does not move toward the 30, there is no way to bring the maritime air masses to those desert areas.
Latitude is the measure of distance, in degrees, minutes and seconds, from the equator. The farther from the equator, the higher the latitude until one reaches the North Pole or the South Pole, which are the highest latitudes of 90 degrees.
