Convectional lifting = air lifted at the leading edges of contrasting air masses frontal lifting = air lifted by flow into a region of low pressure convergent lifting = air lifted by local surface heating orographic lifting = air lifted over a barrier

Air lifted by local surface heating.

Explanation:

Air usually flows vertically, which we call lift. But, air doesn't lift all by itself, it needs help. The processes that lift air, are known as lifting mechanisms.

Convectional lifting is related to surface heating of the ground surface air. Convective uplifting occurs as the sun warms the air above the ground and starts to rise. Air rises and cools, clouds forming and precipitation.The cycle of heating up a parcel of air by conduction on the surface, then the whole parcel rises into the atmosphere as it is colder than the ambient air.
