What occurs to the temperature during convection when lifting agents are involved?

During convection, when lifting agents such as terrain, weather fronts, or thermal updrafts are involved, the temperature of the air can rise due to heating. As the lifting agent causes air to ascend, the pressure on the air decreases, allowing it to expand. This expansion often leads to cooling; however, if the air is heated from below by the surface, such as in the case of warm ground or solar heating, it can lead to the overall temperature of the rising air parcel increasing. This process is especially prominent in unstable atmospheric conditions where warmer air is less dense and continues to rise, promoting convection.

Additionally, the concept of lapse rate comes into play; as air rises, it cools at a certain rate, but if that air starts off as warmer than its surroundings due to ground heating or other factors, it will rise and continue to warm as long as it is unaffected by cooling processes or if it maintains an upward trajectory. Therefore, convection coupled with lifting agents results in a net rise in temperature within the air parcels as they ascend, particularly when they originate from heated surfaces.
