Heat and cold air.
Solar energy the sun
A fluid will move from high pressure to low pressure.
The convection cells radiate heat.
For example a low temperature or high pressure.
High to Low.
Yes warm air and low pressure can cause rising air.
High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.
Differences in air temperature and pressure usually cause wind, otherwise any kinetic energy can cause the movement of air. High pressure goes to low pressure, hot to cold. High temperatures have low pressures and low temperatures have high temperatures. Wind goes to low pressured areas to fill them in.
A Low Pressure system. High pressure systems exist "by default"; meaning that high pressure systems occur everywhere that there are no low pressure systems.
A worn out, tired, high mileage or abused engine could cause low oil pressure.
Usually it would cause low blood pressure from dehydration and hypovolemia.
High pressure yields a more tender food than through low pressure cooking. This isn't for all proteins and ingredients, because the high pressure will cause the food to disintegrate.
A fluid will move from high pressure to low pressure.

low fuel pressure
the orbit of the moon around planet earth
Energy or matter move from high potential to low potential. This case the high pressure mean there is more air in its' volume so it expand toward those spot with lesser air than its' volume. For example, low pressure front may due to the heat cause air volume to expand. The air then move up due to its' buoyancy and that cause the low pressure. The colder and denser air is then draft toward those low pressure front.
Low pressure - cyclone High pressure - anticyclone
