there are 5 major factors affecting global air circulation :
- uneven heating of earth's surface
- seasonal changes in temperature and precipitation
- rotating of earth on its axis
- properties of air and water
- long term variation in the amount of solar energy striking the earth

Four factors that affect global air circulation are the uneven heating of Earth's surface, the Coriolis effect caused by Earth's rotation, the distribution of land and water on Earth's surface, and the presence of major mountain ranges and ocean currents.
Factors which effect the global air circulation include seasonal changes in temperature, rotating of earth on its axis, seasonal changes in precipitation uneven heating of Earth's surface and properties of Air and water. If studied closely often a pattern can be observed in the way these factors effect the global air circulation.
Due to the Coriolis forces, global air circulation is driven in an east-west pattern. The warm air from lower latitude to higher ones, and inversely cold air from higher latitude creating low and high pressure that create global wind patterns.
Global circulation cells regulate atmospheric circulation and distribute heat around the Earth, influencing climate patterns. They play a crucial role in redistributing heat from the equator to the poles through the movement of air masses. These cells also affect weather patterns, ocean currents, and the transport of pollutants in the atmosphere.
The circulation of tropical air is driven by the Hadley cell, a large-scale atmospheric circulation pattern that transports warm air from the tropics towards the poles and cold air from the poles towards the tropics. This circulation plays a key role in shaping global weather patterns and climate.
The circulation of air is primarily caused by temperature differences between regions. Warm air rises and cooler air moves in to replace it, creating convection currents. Other factors that contribute to air circulation include the rotation of the Earth, the distribution of land and water, and atmospheric pressure systems.
The circulation of an air mass is the movement of air within a specific region of the atmosphere. It can be influenced by factors such as temperature, pressure gradients, and topography, leading to changes in wind direction and speed. Understanding air mass circulation patterns is important for weather forecasting and climate studies.
